Dr Tan is a very nice and gentle person and a great doctor for regular family stuff...scrapes and stuffy noses. On more complex issues involving myself or the kids, I always walked out with a vague feeling of uncertainty after each appointment. She certainly has some positive reviews here so maybe she wasn't right for me or my family. Since we moved to Palo Alto Medical Foundation, I can't help but notice the differences in crispness of service, completeness of the explanation and confidence of diagnoses (my confidence and the docs). They seem to have a better handle on the 'science' part. read more

This rating is not for the doctor, as I have not seen her. I called to set up an appointment and was left on hold for 9 minutes - at which point I hung up. Very unprofessional, and after reading the reviews here won't bother with this one... Thanks! read more

Dr. Tan is a wonderful doctor. I am always able to get an appt. in a very short time. She always is very responsive. I cannot say enough about her. I have referred several people that are very satisfied with her services. If you want a doctor that is lethargic and sits and gabs, Dr. Tan is not your gal. She listens intently and always has a solution or test....no waiting months! Dr. Tan is fiercely caring of her patients and their good health. I always feel very secure as her patient knoowing she sincerely cares. Dr. Tans office dispenses Z packs so when I am sick I dont have to wait in pharmacy lines. read more

I am a busy businesswoman and mother so Dr. Tan's efficient yet caring demeanor was perfect. I didn't need to chat with her for an hour, like other Yelp reviewers complained. :-/ It has been about five years since I had a thorough physical and knew it was time to get some "major" work done. I was referred to Dr. Tan by my cardiologist and was surprised when I got a new patient appt the next day! I was seen immediately and was still getting my vitals taken by the nurse when Dr. Tan arrived to the exam room. Wow, nice surprise. She read my history and made sure I got a very complete physical. I got flu and tetanus shots, urine test, breast exam, internal exam, and she also prescribed chest xray, fasting blood test, colonoscopy and mammogram. The day after my visit, the nurse called to give me results from two of the tests. Five stars for both care and efficiency of everyone in her office! I'm already telling family members to see Dr. Tan as well. read more

I read several of the negative reviews that were reported and to be honest, I find them hard to believe. Dr. Tan has been my family physician for many years and if it were'n't for her I wouldn't be sitting here typing on Yelp. I was very sick and she insisted I go to the hospital. Upon examination and further tests, I learned I had a severe case of Sepsys - blood poisoning that just about killed me. Dr. Tan has ALWAYS fit me in for an appointment and even goes to great lenghts to call home to see how we're feeling. It really doesn't get better than that! I love Dr. Tan and will continue to recommend her to anyone and everyone. read more

I am so grateful to have Dr. Tan as my primary care doctor. She, and her staff, are very professional and concerned for my well-being. I usually get an appointment the same day that I call and am treated very well. My concerns and questions are all addressed and I usually get a follow up call to make sure that I am doing well and satisfied with my treatment. These things make me feel seen and valued and I truly appreciate it. read more

Dr. Tan is definitely a match made in heaven for me . She has been my healer for the last 8 years since I novelties the Bay Area . Her MA Elsa was so sweet and very accommodating as well . Elsa simply had a special way about herself . I'd recommend Dr. Tan to anybody from the ages of 7 to 77 . She just that good! read more

Dr Tan is awesome. Their front desk people and billing are the most stupid people that I have ever met or talk to. Got a letter after 4 month stating I have an unpaid balance and will send me to collection if this is not paid within 10 days. Call their office, talked to a gal name Carrie, who should be FiREd yesterday. Have no basic skills to understand a conversation. She told me that I paid a bill of 84.33 cents on the day of service, but it shows that you have an unpaid balance of 84.33. You said that you paid that? ARE U KIDDING me!?!?!? Did you just listen to yourself!?!? I paid the bill on the day of visit and you are billing me to collection? "I don't know what happened I need to ask billing why they are still billing you." No, the correct answer is that you need to have billing call me back. Someone also name CARRIE works at billing and never pick up the phone. It's so stupid. This is just plain stupidity and no excuses. People like this shouldn't even make minimum wages because they don't desire a dime. too bad Dr Tan is such a great dr. Her stuffs should all lose their job immediately. read more

After having a horrible experience with the San Ramon Medical group I found Dr Tan and her staff. what a relief! They are kind and helpful and she is so so nice and very informative. she stays up to date and actually is interested in you and your health, you are not just another number. Love them! read more

I am a husband of 39 years, a father of 4 and a grandfather of 6. I am a professional and I work with professionals every day of the week. My wife and I have been going to Dr.Tan for 5 years now. And from my experience with her today, I know she has no respect for people who are hard of hearing. Today I went to her office for high blood pressure. indecently I wear hearing aids. I will get back to that . Her assistant checked my blood pressure (manually) left arm and it was low 127/81. I asked her to check it again because my machine at home (automatic Omron HEMFL-31) was reading an average 152/102. the assistant checked it again on my right arm this time and it was 122/80. Then Dr.Tan came in , I explained why I was in her office and that I believe my blood pressure is trending up . She had another nurse take my blood pressure(manually) It was 165/105 . She also took a EKG reading. After that Dr. Tan took my blood pressure and confirmed it was high. She said it is what happens as we get older. Then she started talking to me ..but real fast. I asked her to please slow down because I was having a hard time understanding her. Dr. Tan's response was- "maybe you should find a doctor that is a better fit". I asked her what she meant by that ? She said "if I am talking too fast, then maybe you need to find a Doctor that can talk slower. I replied, Is what you are saying, If you don't like how fast I talk, then get another doctor? She said (nicely) yes. I asked her if she knew what bed side manner was ? She started talking fast again. I asked her if I was just a patient, or a Patient and a customer. She said I was not a customer. So then one can only think that if you are wearing hearing aids, have clogged ears if you have a cold or flu or are deaf, then Dr. Tan does not want to be your doctor because she is not willing not change for those who have a hard time hearing . read more

I'm very happy with Lorena Tan. She is very caring, has a sense of humor can make a fast diagnose. I went in one day because I wasn't feeling all that well. She found that I had bronchitis. Treated it before it went into the deep cough and I was well in no time at all. She did refer me to a doctor for a minor surgery, and I found that I wasn't too pleased with the referral. Other than that I have absolutely no complaints about her. I recommend anyone who needs a doctor to see her. read more

I have been a patient of DR. Tan's since moving to the area almost 4 years ago. She is fast, efficient, always listens to my questions and is very thorough in her responses. Equally her staff is exceptional - warm, helpful, and quick. I have asked to be seen on short notice and they always are able to work me in - even if I need to wait a little longer to be seen. I highly recommend Dr. Tan! Jessica Sbragia read more

Outstanding doctor and extremely professional, my insurance went up $700 per month do to our current administration and i still refuse to switch to a lower cost insurance because of potentially losing this doctor and her practice with our new insurance carrier. She is very personable and extremely freindly read more

Dr. Tan is a nice woman and her staff are competent, however she seems rushed which makes me feel rushed. I think this is mainly because she talks so fast. I usually end up with questions after my appointment when things sink in because it's such a whirl when I'm there. I'm pleased to say that I always get a call back from the office with answers. Would be nicer though if I had time to think over what's going on when I'm there. It would be more comforting and calming if she were able to slow down. I've almost forgotten what I've come for sometimes. My last visit I made an appointment for a TB test with my annual, but I almost went out the door without doing it and they didn't seem to have written that down when I made the appointment, but they were happy to do it when I turned around and came back. My mother also sees her and has had good experiences with Dr. Tan following-up to make sure my mom got needed tests and after an operation to see how she was doing. read more

Great Doctor and polite and professional front desk staff. Dr Tan was very attentive and it appeared that she genuinely cared about my well-being. She listened when I had something to say and that in this day and age of insurance company Dr to patient allotted treatment really meant a lot. I'm definitely going to choose her as my primary care doc! read more

This is the worst doctor I have ever been to. Long story short she made several critical errors... that every doctor I have seen since said should not have been made... I almost died at home from cardiac arrest, called her on-call doctor who told me to stay at home it was no big deal, luckily I did not listen and was admitted to the hospital and lived. In addition I saw her again for what I thought could be an ear infection and she looked in my ear for 1 second said it was an ear infection placed me on antibiootics, only to find out that I actually had a sore in my ear and there was not infection at all. She is incompetent, negligent, and dangerous to medicine... if you want to have a effective doctor look elsewhere. read more

She was never clear about the diagnosis on what was wrong with me. She made me go get a blood test and a CT scan on my brain. Both came back fine and now im stuck with a 700$ bill. She does not know what she is talking about and questions herself which is why i had to see two other doctors for her to be 'sure' i was fine. read more

I love Dr Tan. I seriously do. It's just the staff I can't bear anymore. Getting referrals handled at this office is a nightmare. They are either never submitted, never contact the patient once approved (yet writes it in their chart that they've done so), selects incorrect dr for the issue (I've gotten pediatric drs even though I'm clearly an adult), submit incorrect referral paperwork so the referred office cannot do the work, and have given out incorrect contact numbers every time. It's soooooo frustrating because I've gone weeks/months not getting my medical issue taken care of by a specialist because of this PCP staff. I ALWAYS have to call them for a follow up. Today I just had to visit in person to actually get a correct phone number. Thank God I was off of work. Sadly I'll be leaving Dr Tan once I find a decent replacement. She's the absolute sweetest, but This office is more of an inconvenience than a help. read more

Dr Tan is amazing! I was so sad to see the below average ratings for her. She has been my doctor for about 4 years now, and I could not love her more! I love her warm bedside manner, love her sense of humor, love her intelligence. I'm still relatively young, so I haven't had too many major medical conditions but she was outstanding on the one occasion that I did have. When I had just turned 28 I was in between jobs (read-no healthcare) and I had an "incident." I woke up in the morning and my mouth didn't work right (best way I can describe it.) Tried and tried to talk as much as possible, thought I slept on it wrong. Called my love in San Diego who was in the process of moving us back home to Livermore. In between the "what?" and "huh?"s of our conversation he says-"eh, it's probably Bell's Palsy, you'll be fine" (FYI-he's a paramedic and fancies himself quite the doctor ;-)) I go to work, where they insist something is wrong and I should go to the doctor. An argument ensues where I remind them I have no healthcare, but they win. Off to Dr Tan I go at 3pm. I had not seen her in over a year, but she got me in anyway, knowing I had no healthcare. She discounted her exam and let my love pay over the phone. She realizes that I've had a stroke and sends me for an MRI. Because she's sensitive to my situation, she refers me to a great place in Pleasanton who seriously discounts because I (my parents) are paying cash. Tests come back that I'm partially braindead (people have been telling me for years, now I finally have proof!) At 5:30, she reveals the results to me over the phone while I'm still at the MRI office and lets me know that I have 2 options. Either go straight to the hospital or a neurologist. The last thing I want is to be hospitalized, so she gets me in to see a great neurologist after hours (Dr Stan Lin, I believe his name was) At this point, I think I have brain cancer, I'm dying, I'm totally freaking out and Dr Tan could not be sweeter or do enough for me. Just some girl she barely knows with no healthcare. Long story shortER, I end up at Valleycare anyway, heart surgery at Alta Bates, am fine today. Lesson being-be super careful with which BC you're on ladies (and don't make a 9 hour drive with no stops or try to take away my doggie) and have a great doctor who is willing to jump through hoops for you! The part that makes this story even sweeter is that a month later I was having dinner with my love at Zephyr. Dr Tan walks by, recognizes me and jumps into the booth to give me a huge hug. She is the nicest lady IN THE WORLD. PS For people who have long waits, it's probably because she's dealing with emergency stroke victims like me. She won't turn anyone away and I prefer that in someone I trust my life with. She is also quick to refer (like sending me for an ultrasound when I was having some transient nausea) which I also love. I have a phobia of doctors who pretend like they know it all when they have no clue what's wrong with you. Refer away! I'd much rather be at the specialist if it's not super minor. read more

Best doctor in the bay area! Dr Tan is a very caring and the office visiting are in n out! They usually see me the same day I call! And the staff there are very friendly!! Thank you for the great service! read more

My wife and I have been seeing Dr. Tan for about three years. We think she is fantastic. She's smart, knowledgeable and efficient. And the office staff are really great which I can't say for prior doctors I've visited. --They're always friendly and calm despite the busyness that occurs in the usual doctor's office setting. And one heads up with Dr. Tan, at times she can go pretty fast. I've found that when that happens all it takes is for me to say "OK, this is going a bit fast for me, can we slow it down a bit" and then she takes a breath and the pace slows. ....I guess the reason I like her is that in addition to her expertise I feel like she's "one of us" and not some removed figure. read more

Dr Lorena Tan is a great Dr to see for any reason. She is very caring and concerned about what you have to say. She treats her staff nice which tells alot about someone. I have been in other offices where the Drs aren't too friendly to staff and just want to rush you in and out. I highly recommend her! read more

I cannot say enough good things about Dr. Tan. I have been a patient of hers for the last 3 years and I am so happy to have found her! Dr. Tan is extremely thorough and informative as well as caring and compassionate. I still find it refreshing to have a doctor who actually listens and responds to my concerns. I have seen Dr. Tan for a number of issues and also for yearly physicals. She has never failed to call me personally to explain the results of laboratory testing. She always has lifestyle recommendations at my visits which I greatly appreciate. My referrals from her have also been excellent. Dr. Tan's office staff is very efficient. They were also extremely helpful this year when I changed insurance plans. The front office seems very organized and I have never had a long wait to see the doctor. I have to disagree with the negative reviews that Dr. Tan has received on Yelp. I am employed in a health care field and I do believe that she has "a handle on the 'science' part." To her body of knowledge she adds a great sense of humor and a warm personality- a combination that is rare these days in human medicine. I strongly recommend Dr. Tan to anyone that is looking for a general practitioner in this area. read more

Dr. Tan is an exceptional doctor. My family of seven has been seeing her for nearly a year. She takes her time with each of us and listens to our concerns. She addresses these issues and then goes out of her way to make sure she covers all the bases of care to make us feel confident that any concerns were alleviated. We adore her. She is kind and caring and always tries to make us feel comfortable. Her office staff is superb and will always make an effort to get us in to be seen. I never feel like her time with us is rushed or that she is running a revolving door practice. She is concerned for and loving of her patients. I would recommend her, not only for her expertise, but for her being humble enough to admit when an issue needs to go to a specialist and then sending us to one. Fabulous doctor:) read more

Dr. Tan is a WONDERFUL, skillful, caring doctor ~ our family doctor for years. She helped me, my daughter and SAVED my co-workers life. My daughter was only 9 and suffered from migraines (the kind that make you throw up and lay in bed in darkness and silence) and with Dr. Tan's care and treatment they were gone within a few weeks. Dr. Tan had a great rapport with my child and treated her with respect and explained her health in ways she could understand, and more importantly, take part ownership. The migraines? They went away and have not returned. My coworker had a sore throat and instead of assuming it something easily treatable Dr. Tan did some tests to rule out the worst possible causes. Good thing...it was cancer of the esophagus. It was diagnosed so early that the chemo and radiation worked and within a few short months she was cancer free and has been for years! Lorena Tan deserves nothing less than 5 stars!! read more

I cannot say enough good things about Dr. Tan She has a great bedside manner, I felt comfortable with her immediately. She is very thorough and takes time to listen to your questions and provides comprehensive answers. She is also abreast of new medications, and is proactive about testing anything that may be of issue. If you are interested in taking a proactive role in managing your health, she's the doctor to help you do it. And her office is spotless, and her staff are extremely helpful and polite. read more

I usually do not write reviews, but I am compelled to write one. I loved Dr Tan and have been seeing her for many years. I came in for symptoms of menopause and wanted to see if there was anything I could take "natural" for it. Dr Tan rushed in and seemed in a hurry, she spoke to be very briefly. I felt like she did not want to take the time to hear me out, she started writing a prescription for a anti-depressant, which suppose to help with hot flashes. It made me angry that she was so fast to write a prescription. I was hoping to either have some suggestions for alternative medicine rather then quickly write a prescription, or some blood work. I will not be going back. Maybe she is seeing more patients a day and her care is not what it use to be. read more

I first want to say I know 100's of family practice physicians as part of my professional job. Dr. Tan is among the very best! I trust her with my life, which is why my family and I are patients of her practice. Dr. Tan is always at the top of my list of doctors I recommend to everyone. She spends her weekends attending medical seminars and her life is devoted to her patients. I seriously can't say enough kind words about this sweet, extremely knowledgable, and tender hearted physician. She is wonderful :) read more

I really loked Dr. TAN, BUT I DO NOT LIKE HER STAFF. They are unable to get you timely responses to your questions for Dr. Tan. Sonce dhe does not do email ot imossible to get a hold of her for anythimg unless you come.e in for an office visit. It is not right to force people to pay for un needed office visits. I had a visit with her less tha a month ago, i called for follow 2 times the third time they said they had no record of my calls or messages and then daid i had to come in again for the same problem. read more

Superb Physician. Kind, considerate, listens to your every word! Very thorough!

I've always been able to call up and get in to see Dr. Tan whenever I needed to. Yes the office is busy and the time is limited, but I feel she listens to my needs and helps me. read more

Dr. Tan is a caring, efficient, knowledgable physician who runs an on-time office and always makes room for patients in need. When I have questions, she is a fountain of information, quoting studies and offering a range of options. She takes time with you when you need it. Her staff is well trained and cheerful. Her office calls with test results as soon as she gets them - it took my urologist three weeks to call to say my ultrasound was fine. Thankfully I already knew because of Dr. Tan. She listens and supports the approach that you are comfortable taking. If you want medication she will prescribe it. If you want to try more natural solutions she will support a plan for going that route first. She has an excellent network of physicians to refer you to if needed. I recently moved to Livermore after getting married. The first time I met Dr. Tan, I wasn't sure she was the doctor for me. She has been my husband's doctor since she opened her practice. After seeing her once, I was convinced that I would be her patient for life. read more

Dr Tan is highly efficient, his office staff is very flexible and can help schedule you in if you need to see a Doctor right away. I truly appreciate their effort in this regard. Everyone involved is very friendly and work seamlessly as a team. She is very knowledgeable, highly talented and can multi-task without losing her smile and patience with her patients. I will not hesitate to recommend her to anyone for your Family's needs. read more

Don't be fooled by the smile and acts of kindness. If you question her diagnosis or recommendations, she will become angry and insulted. She is a doctor who wants to be in charge, not listen to her patient's views or desires regarding treatment. If you ask for a second opinion, she will drop you and refuse to serve you. If this is the behavior of a great doctor, count me OUT!!! Signed, Gone somewhere else where they listen and rationally accept questions instead of acting insulted or perturbed. read more

I am a new patient of Dr. Tan. I find I am drawn to her beautiful face, where I see kindness. Dr.Tan is professional, & seems interested in me as a person. read more

The harshest physician I ever met in my life ! I would never go there again or recommend her to anyone. I saw her only once, for a physical that I had requested, after we moved to Livermore. My blood tests results showed a little high glucose and cholesterol; everything else was fine. I had had that before, worse numbers in fact, and I knew that it meant to follow a better diet and more exercise. I am a very busy person and when her office called me for a follow-up appointment I explained that I did not want to make an appointment then for those reasons. After a few days I got a certified letter from her saying that she was discharging me as her patient ! No reason was provided. I called her office for an explanation, I had to insist for an explanation, and finally they told me that I had not "obeyed" to her request for a follow -up visit and that my other "sin" was that I had requested a physical for my first appointment, thing that she does not like!!! I asked that she called me personally since discharging a patient is a serious thing to do but she never did. All of this resulted in wasted time for me to find a new doctor, write this review... and stress because the whole thing did upset me a little although it's somewhat comical that my doctor "fired' me...but I am happy that I got rid of her from the beginning. read more

THIS IS A VERY LONG REVIEW, BUT VERY WORTHWHILE. Please read! I first met Dr. Tan about a year ago, and was blown away with how kind and understanding she was. My previous doctors could hardly compare to her, as I felt like she truly wanted to help me and I wasn't just another patient she had to get through so she could go home. But throughout this past year, her negligence and lack of complete evaluation has caused extreme health problems for me. This is not a review to defame her, but only one to warn others that when she is in a rush and there are patients after you, you will most likely experience an unpleasant and rushed visit. In the beginning of 2018, I caught several colds and a stomach bug that was going around. I was already on antibiotics for a bladder infection and was having horrible stomach pains. Dr. Tan knowingly prescribed me another set of antibiotics to treat my "unknown stomach bug," which caused me to become very ill and ruined my GI system because I was taking 2 different medications at the same time. I still felt that she was a caring doctor and continued going to her, and wrote this event off as a simple mistake because we are all human. Then in August 2018, I went to her for my intense menstrual cramps, asking her to refill my prescription of pain medication (naproxen). Instead, she advised I take 2 Aleve every 4 hours as they are technically the same medicine. While my family and I were on vacation, I took the medicine as she prescribed me to for a few days while I was experiencing extremely painful cramps. I am not a doctor (although I do admit it is my fault for not double checking or making sure the dosage was correct), but I had ruined my stomach lining by "overdosing" on Aleve. I was forced to go to the ER after several weeks of horrible stomach pain, made worse when eating. I lost over 10 pounds in less than 2 weeks, and this continued over a course of several months where I had to recover. Nearly 6 months later, I am still recovering from my gastrointestinal issues caused by Dr. Tan's error, and find it very hard to enjoy eating as my body can no longer process foods I was very easily able to consume before. I've always had issues with my GI tract, but this event has only made it worse. In addition to all this, the ER doctor advised me to skip my period for several months so I could avoid taking pain meds and allow my stomach lining to heal. I had to go to Dr. Tan for this, explaining everything. She saw no problem with her original prescription of 2 Aleve every 4 hours, even though the ER doctors were horrified when I told them I had been taking that much medicine. Dr. Tan told me that my current birth control (which I had been taking to control my irregular periods and menstrual cramps) would allow me to skip my period if I kept taking the pills continually. I did this and didn't have a period for 2 months which was great! And then I randomly got my period one day and it didn't stop for 7 WEEKS. Turns out Dr. Tan, yet again, made an error and the type birth control I use does NOT allow me to skip my period like that as it releases a different set of hormones each week, which confused my body. My birth control was clearly listed on my chart, and as a doctor she should have double-checked or found out if I was capable of skipping my period with that specific pill. Her overwhelming amount of patients and lack of time to carefully listen to you leads to extreme inconveniences for her patients. If your illness is anything more serious than the common cold or flu, I recommend you do not visit her. Take the time to see a specialist who can accurately and thoroughly diagnose and help you, as Dr. Tan was simply not equipped to deal with my symptoms and caused a hailstorm of additional problems that could've easily been avoided if she had taken just a little bit more time and patience. read more

If you want a doctor who really checks your ears, chest, lungs and body do not go to Dr. Tan. She is in such a hurry that when she checks your lungs do not breath in and out and she will never notice. As for your ears she would not know if you have something wrong because in a split second no human can actually see the ear canal. If you question her about tests she gets upset and tells you that you should get another physician. Which I plan on doing. read more

My whole family goes to Dr Tan including my mom who was a nurse for 37 years working in many areas of medicine. My husband comes from a medical family as well so we've been kind of immersed in this area. Our experience with Dr Tan has been nothing but positive. She is knowledgeable, up to date, compassionate, principled and wholistic in her approach. Highly recommend her. read more

Dr. Tan if very thorough and professional. I always feel like she takes the time to listen.
