My baby was delivered by Dr Yaron Friedman, who was working in Dr. Klein's office at the time. I would have appointments with the both of them throughout my pregnancy. Both doctors were very personable with a great sense of humor. They gave me a due date of February 11th, my last appointment was about a week before and I was seeing Dr. Klein that day. At the end of our appointment he asked me what I was going to name my baby, I told him her name, he said it was nice and wished me well after the ultrasound. I was the last appointment that day, and on my way out he was sitting there with his guitar playing Eric Clapton for my baby girl. I'm crying as I type this because she was born February 10 just 20 minutes shy of her due date... that was 20 years ago. My daughter is in her second year of college now... Can you guess her name? read more

I had a chance meeting with Dr. Klein and Dr. Rose 10 years ago in the ER. At that point I had suffered with very painful ovarian cysts and endometriosis since childhood. My situation had become impossible to deal with as a large tumor had developed and was causing the most severe pain of my life. Dr. Klein graciously agreed to meet me at the John Muir Medical Center just two days later on a Saturday (his day off) and perform surgery on me. After the surgery I noticed something absolutely amazing...I finally had relief from the pain after 20+ years!! I cannot thank Dr. Klein and Dr. Rose enough for everything they did for me. Years later I still think about the kindness Dr. Klein showed me during that time and the fact that he did not dismiss my symptoms as so many doctors have done. The thing about my condition is that it doesn't actually go away and can only be managed. Sadly, after the surgery with Dr. Klein I had to switch to Kaiser. The level of care between Kaiser and Dr. Klein cannot be compared. If I had the finances, I would run back to Dr. Klein right now, today! If Dr. Klein is your OBGYN, consider yourself lucky. Although my time with him was brief, it was obvious that he genuinely cares for his patients' well-being and that he's a brilliant, fantastic, and remarkable doctor/surgeon. read more

Dr.Klein and his staff are hands down the best in the Bay Area. I was referred to Dr.Klein by an urgent care Dr. in Walnut Creek and I cannot express my level of gratitude. I was beyond nervous to get my IUD removed after 5 years given I had a very painful and uncomfortable experience when I had the device put in by a different physician in Oakland. Dr.Klein explained everything he was going to do and asked me if I had any questions, concerns and if I was comfortable. When I mentioned that I was nervous his office manager Pary approached me and held my hand. This meant so much to me because I felt like I wasn't alone in the process and I had the support that I needed at the moment. Needless to say the whole process was a success and I did not experience an ounce of pain. If you are looking for a lifelong OBGYN Dr.Klein is absolutely the way to go, trust me. read more

Dr.Klein is the best OB I have came across. Been seeing him for the last 6 years and for all three of my pregnancies. His staff has always been great, especially Freddie she is always helpful with any question I had & very professional. I would recommend him to any of my family or friends. Sometimes the waiting period may be long but overall dr.klein is a great doctor. read more

I will be 100% honest. Initially, I called the office to see Dr Rose as a new patient, they share an office and I was following Yelp reviews. I had an immediate issue and Dr Klein had appointments that would be sooner, so I said ok. Best decision ever. I have never felt uncomfortable with Dr Klein and he has been nothing but helpful. Yes, he does have a particular brand of humor, but really, going to an obgyn is unpleasant enough, I appreciate him cracking a joke. Maybe it is a personality thing, but I've never had an issue. I have never felt rushed, he always listens to my concerns, and he makes sure I am well informed and comfortable with every plan of action. It's rare to find an ob/gyn that doesn't run in and out of the room before you can ask a question. He has squeezed me in, skipped lunch, even offered to meet me on the weekend during his on-call rotation if need be. I've had to bring my toddler to appointments and he is always kind to her, too. As a SAHM, it is pretty awesome that he didn't bat an eye at her sitting with me during an exam. It allows me to get the medical care I need without having to track down and pay for sitters (which would normally mean a lot more hassle or even skipping care). Shout out to his super sweet nurse Sonia and the woman that makes appointments (super sorry, I don't think I've gotten your name yet). They are always great to work with. Yes, the wait time can be long and phone calls can be tricky, but they have always returned calls promptly (same day). I know if I'm waiting that the doc is either across the street delivering a baby or making sure another patient is getting the same level of thorough care that I enjoy. I can't fault them on that! It's not like some offices where you can see the doctor just sitting there while you wait. The waiting room is pretty comfy with a TV and fruit-infused water. read more

Two hour wait, just to get an ultrasound? The point of an appointment is to avoid an unnecessary wait. Completely unacceptable. read more

This is our 2nd visit here. The 1st time, we had to wait an hour in the waiting room. Then another 30 minutes in the exam room. Once there, it's a closet sized exam room. Multiple people walking in during her exam. Very unprofessional Second visit 1.5 hours in the waiting room so far. We can see the doctor through the window just walking around and eating talking to his staff. They could call and let you know that they're running late or that they don't value your time as a patient. Update: 2 hours and still waiting in the sitting room. I'd say find a better OB/Gyn, unless you like your time being wasted. Zero stars.... read more

Best OB-GYN any could ask for. He has wit and charm and the funniest personality. He's also one that will listen with compassion and give you the fatherly hug you need. He helped me deliver 4 beautiful children and to this day, they all know him as "Uncle Lou." Thanks you Dr. Klein for all the wonderful memories you have given me over the years. You are your staff are the most amazing people ever and you will always hold a special place in my heart. read more

I have been a patient of Dr. Klein's for 4 years now. I am 38 years old with 6 kids and Dr. Klein delivered my 6th child. He made me feel comfortable and actually took the time to listen and address each of my concerns (which there were many of) without making me feel like I was overreacting or wasting his time. He is extremely thorough and never rushes through our appointments. I would highly recommend him to anyone. read more

I've been a client of Dr. Kleins for about 9-10 years now. I'm 34 weeks pregnant and about to have my second c-section with Dr. Klien. I cant say enough about his patience, kindness, and intelligence. No question I ever have is too crazy, he always has an answer. His office staff are about the nicest people you'll ever meet. The entire office keeps such a calming, fun atmosphere going that even when you go into the office feeling like a giant uncomfortable pregnant woman you almost instantly get in a better mood. I have had to wait a few times in the office, but this is only because one of the doctors would be called out across the street to take care of another woman in labor. So I cant really fault them for putting us girls in labor first! I would hope that If I was across the street having an emergency they would run to my aid as well! Wouldn't all of you? He has another doctor in his office, Dr. Rose. So when you go into your appointments you alternate between the two doctors. Dr. Rose is extremely adorable, knowledgeable and seems to have the same calming effect as Dr.Klein. When he delivered my son 8 years ago, there were complications and we had to do a c-section at the last minute. He was not far from John Muir and was ready to go. I would highly recommend this office to anyone having a baby. They really make the entire experience less stressful and more enjoyable. read more

I see Dr Klein at least once a year, sometimes more often when problems present. I was recently released from the emergency room with "unexplained pain'" originally believed to be an appendix and later adhesions. A CT scan showed possible inflammation in the pelvic region and I was referred to an OB/GYN. I went to Dr. Klein for follow-up and to alleviate my concerns. He was very thorough in performing an in-office ultra sound and other testing to rule out gynecological issues and to make sure there was no inflammation. Again, as is his style, he spent adequate time with me, answered my questions, and brought his usual human element into the medical appointment. Assistants Perry and Freddie are alert, involved and very helpful in a number of matters. The office staff and the atmosphere they create are very welcoming and I always leave there feeling good. I recommend Dr. Klein to anyone looking for an OB/GYN - especially one that you can talk to, one who will offer you quality time in your appointments and answer your questions, and one who will care about you and your condition.! read more

If there was an option for no stars I would give it to him. He is the most unprofessional doctor and should not be able to practice. I went to Dr. Klein because I was referred to him by the urgent care in the same building as his practice. The first thing that got to me was how long you would have to wait to be seen. Now I know your appt. are not always on time but this waiting was 30-45 minutes after my scheduled time. Second I was in my waiting room for an hour waiting to be seen while he was in his office blabbing to a client. It was so long that I almost got up and left. Not only that his staff member had to remind him that I was waiting and there was no sympathy or remorse when he came in. The very last straw that made me leave was a comment that he had said to me my last visit with him. I was 34 weeks pregnant and he had to check my cervix. There was only him and I in his room as he did my exam no one else which I though was weird. As he went to do my exam he said, " is anyone else allowed in here besides me?" I was in shock and froze. This comment made me feel so dirty and violated. I left my exam feeling like what just happened. That day after frantically trying to find an OB to take me ( mind you I was 34 weeks and no one would take me as I was too far along) I finally found one that was sympathetic to my story! I got a phone call from a staff member asking why I was leaving. I told her what had happened and her exact words were " oh ya he says that to a lot of our patients." I was shocked! It was like she had laughed it off! This guy will never be able to say anything like that to me again and I hope after this he won't be able to say it to anyone else! Especially to a young girl! read more

I do not recommend this place. Both times I went there I waited for 45 min or more. They could have given me a heads up by phone that I would be waiting that long so I could be at work rather than in the doctors waiting room. Second, while the doc was checking everything he was talking about setting me up with his son. No I do not want to meet your son after you look down there thanks for the offer. Third he prescribed me a trial birth control instead of the one I was on prior and I had to return two months later and sit in the office forever again so that I could go back to the one I was on. Not a good experience doc. read more

I loved my time with Dr Klein and I'm definitely coming back. He was with me every step of the way! The ladies in the front office are very sweet and helpful. read more

I switched to Dr. Klein in my 2nd trimester and I couldn't have been happier. I debated about a VBAC or C-section and he supported both. Yes, you do end up waiting a long time, but its because they never rush a patient out. They take the time to answer every single question and focus entirely on the patients when its their turn. I read more

I won't be returning to Dr. Klein's office. His sexual remarks make me feel very uncomfortable. Every time I went I felt like he would always find an unnecessary reason to check my vagina.. Before I had my daughter he told me my vagina felt like a "very tight exit" for the baby.. After having my baby he asked me how breast feeding was going and if my breasts were soar and I told him no and next thing you know his hands were on my breasts without asking! I literally had to push his hands away. I felt so violated. He is an old pervert! Aside from all that, the rooms were always dirty and it looked as if his equipment wasn't being disinfected. One time there wasn't even clean paper for me to sit on the table! I don't recommend this office whatsoever! read more

My wife took an appointment with Klein because her regular doctor was on vacation. She needed an emergency procedure and could not wait for her doctor to return. Although Klein was polite in his office- I got the impression he was little more than an educated car salesman. He was very impersonal and cold towards my wife; who was nervous and emotional during the procedure. He seemed to be in a rush and had repeatedly stated he was doing us and our doctor a favor by seeing my wife. Unfortunately, we did not get up and leave, like we should have done. I would NOT recommend this doctor to anyone. read more

Dr. Klein is a great physician. He's very personable and takes the time to talk to his patients. He's no BS when telling the facts, but it is refreshing and honest. He is a solid communicator, and takes academic medical theories and brings it down to understandable conversation. He listened to my concerns and made sure I didn't leave his care without feeling safe and cared for. I felt very comfortable in the examination room with him and fully trust his judgement. The staff was also equally kind, accommodating, and practical. A fantastic practice. read more

Although I do agree that the wait at times can be very long, but Dr. Klein is an amazing doctor. He delivered my first child back in 1996 and I've been his patient since. He is very thorough in explaining everything, he is compassionate and does take every thing that is going on in your life into consideration. He is super personable and its not the kinds of doctor to push you out in a hurry as most doctors would. It sucks how some of you gave him a 1 star, he really is a great doctor. read more

There is too many great things I want to say about this OB/GYN office but I will try to keep it short. I moved to CC county when I was 4 months pregnant and was lucky to be accepted by Dr.Klein's office, many offices would not even return my calls. During all of my office visits I was always greeted with at most care and kindest by all of the staff. I never felt like I had to wait too long to be seen but if I did wait - I knew once its my turn with the doctor or Mary N.P., all of my questions will be answered and all concerns will be addressed thoroughly. Never did I feel like I was rushed. I am so grateful to Dr.Klein and rest of his team for their guidance during my first pregnancy, their support and for delivering my beautiful baby boy! Thank you. read more

My beloved gyn retired and Dr. Klein, her recommended colleague, agreed to take over all of her patients, should they wish to go to him. I have to say that I did not actually meet him. On my way driving there, his office called to say he had an emergency, could we reschedule. When I returned 3 hours later, he had another emergency. That's fine; sure, it was inconvenient (especially since I don't live close by), but doctors have emergencies. When, after already waiting 45 minutes, the truly unfriendly, unsmiling young nurse brought me into a room and said she thought it'd be at least another 20 minutes, I chose to leave. In truth, I just didn't get a good vibe from the place. It was really really busy there, there were a lot of young pregnant girls and their bf's there, everyone looked absolutely miserable, and there was a big-screen TV blaring some talk show. It just didn't make me feel the kind of relaxed I want to feel when I go to any doctor, let alone a first visit to a new male ladies' doctor. When I got home, Dr. Klein himself had left a message for me, apologizing for what happened. He sounded genuine, and, certainly, he didn't have to call. That let me know that he had awareness and a sense of care for his patients. I would give him 4 stars for that phone call and 0 for the atmosphere, so I'm giving 2 as the median. In any case, after all is said and done, it's not the right practice for me. read more

Aside from his wait time, I don't have a single complaint about Dr. Klein. During my second pregnancy in 2011, I had a horrible time with nausea. I spent a week in the hospital. I was diagnosed with Hyperemesis gravidarum. I basically couldn't eat or drink anything. Dr Klein did everything possible to make me as comfortable as possible. Hear I was miserable and leave it to Dr. Klein to make me laugh. He is good about that. Upon being discharges from the hospital. He set up with a nursing agency to come to my home and keep my on IVs & Zofran pump. I thought for sure my baby would be born malnourished. Dr. Klein continued checking on me and cared for me during my entire pregnancy. During my labor and delivery, he still managed to come in and crack a joke or two, and make me laugh. My labor and delivery was a walk in the park thanks to him as well. I am eternally grateful for his care and my baby Noah. read more

I've been under Dr Klein's care for almost 20 yrs (my Ins had changed 10 yrs ago & I had to see another OB/GYN) so I left a great job to find one that would allow me to getback to see "Dr Lou". That being said, I've read the reviews on YELP and realized that those who gave low ratings or had complaints about his open and straight-forward way of talking to patients must be of newer generation that never had the luxery of a doctor that is a kind and caring person coupled with with being very knowledgable practitioner. He spends a lot of time with each patient and asks about their life in order to enable him to see the big picture of what is best for them with regards to their care, thus the reason I don't mind the times he runs behind: I know he is taking care of others as individuals and not as a production line of in-and-out ASAP to squeeze as many in a day as possible for monetary gain. If you want a well-educated, very experienced, real human being to take care of you, Dr Klein is a great choice. read more

Dr. Klein and his staff are amazing! He took such great care of me and my baby, even for being a late transfer after a tough experience with another practice. After having such a complicated pregnancy I was so relieved to have found his office. Shout out to all the wonderful yelpers that lead me to call his office for help. Best OB/GYN in the area! read more

Dr. Klein is the best doctor in the world. He reminds me of that old saying "Good things come to those who wait" reason I say this is because sometimes you have to wait on him but it is so worth it. He has been my OBGYN for last 5 years and have seen me through some trying times. He also delivered my one and only Son and that was a hard delivery but he got me through it and it was even painless. I ask dr Kline all the time when is he retiring not because I'm ready to see him go but I want to know how much time I have to have another baby lol. I couldn't see no one else delivering my baby but him. read more

This office deserves no stars whatsoever. This is the most unprofessional medical office I have ever been to and I am in disbelief that people actually come to this office. Majority of the medical staff is unprofessional and don't have a sense for patient care especially the medical assistant that barged into my room without knocking when I was half undressed on the exam table waiting for the doctor. And to top it off, she didn't introduce herself nor apologize for barging in. She just rummaged through the drawers and once she couldn't find what she was looking for, left and slammed the door. Apparently no one taught her manners and proper etiquette. I don't know how people like that have a job, let alone hold a job in patient care. Sad sad sad! And what kind of office makes a 33 week pregnant woman drop off their own lab specimen to the hospital? Don't offices have a courier for that? And to make it worse, the lady who works in the back office of dr kleins office has the nerve to call me once I get home and with a major attitude accuses me of not dropping off my specimen correctly because I refused to check in at admitting! No one told me to check into admitting and why are u making your patients drop off their own lab specimens anyway? What a joke this office is. And this lady needs a major attitude adjustment. Once again, don't know how ppl like this are in patient care. To top that off, she said they won't run my specimen now and if I want it ran, I have to come back! Screw you! Then has the nerve to ask me if I'm having contractions? Ummmm, that's why I got the specimen drawn! I'm having contractions and have severe abdominal pain and your office made me walk my own specimen over! She has no common sense! And the icing on the cake is how unprofessional the Doctor is. What kind of doctor makes sexual innuendos to his patients? He made comments about having an orgasm on my first visit and told my husband he was unimportant. Wtf?! I was appalled at what was coming out of his mouth. And on my second visit, You were over an hour late to see me, and come into the room with an attitude. He tells me "sorry, it's just so happened you ended up behind a patient that had too many problems." Why are you bad mouthing your patient? And the walls are so thin, that I could hear everything they were talking about in the next room. Isn't that a hipaa violation? SMH!! It makes me wonder what he says about all his patients. Maybe that's why you have an office full of ppl that have no compassion for patients. I don't know how they are still in business. And once he learned that my specimen won't be ran at the lab, he called and stated "well there's not much I can do for you. I don't think you're having contractions anyway so you'll be fine. If you want it ran, you have to come back!" Screw you! I just went through the worst visit of my life, 33 weeks pregnant, stressed out and in pain and that's all you have to say? You're a joke and so is your office! read more

I must give a shout out to Dr. Klein. Although I no longer see him (for reasons completely unrelated to him), he was one of my ob's during my very high risk pregnancy. He has a very funny, quirky sense of humor, which might not play out with some people, but he was definitely my "cup of tea". When I would freak out, he would calm me down by making jokes. He was also very instrumental in saving my life when I had a life-threatening complication during my delivery-believe me, he's a consumate professional when the going gets rough. In addition, his office team of caring, professional women should be "the model" and the standard for the obgyn industry. They were incredibly caring, sensitive, and funny. Thanks for everything Dr. Klein! read more

If you value your life or your unborn child do NOT see this a hole! My whole experience with him was terrible but come delivery day he decides to play "whos going to have a baby first" Takes off on my to help another patient while im in mid push.. Needless to say I almost lost me life as well as my child's life. This man should be in jail and should be disbarred!! Please save yourself from what I went through! I would not wish it upon my worst enemy. read more

I would not recommend Dr. Klein at all. Had irregular bleeding he immeditely wanted remove my uterus. He gave me birth control pills , gave me such a bad side effect bleed more, went back he said he never heard of it. He is the worst OBGYN I have ever seen. Went to another OBGYN he had corrected my problem , and told me everything Dr. Klein did to me was incorrect. Dr. Klein was pushing me to have Hysterectomy, which he does that , an old fashion way. He has a terriable personality. read more

I have been a patient of Dr. Klein's for about 10 years. He is an experienced doctor who takes the time to answer questions and has a relaxed manner to help his patients feel comfortable. Recently when I needed some assistance over the weekend, I was relieved when I heard that Dr. Klein was on call. He promptly returned my call on a weekend evening and followed through to assist me. I can recommend Dr. Klein and his staff without hesitation. read more

I have been seeing Dr Klein since he delivered my daughter in 2001. He is a great doctor with a sense of humor and in his field very much needed. He is compassionate and caring and loves to joke around with his patients which I feel makes your uncomfortable appointment more relaxing and takes your mind off things. Lets face it no one looks forward to their OB GYN appt right! If you are looking for a serious office that treats you like a patient and not a person then keep looking. Thank you, Dr Klien and staff for being great the past 14 years. read more

I left this office, today, shaking and in tears. I was shocked at the amount of unprofessionalism and lack of courtesy for patient care displayed by Dr. Klein and his staff. Today was my second visit with Dr Klein. My first experience was for an urgent matter regarding my pregnancy. I had gone in for constant ligament pain, something that I hadn't experienced with my two pregnancies prior. I waited for 1 hour past my scheduled appointment time to be seen. When Dr. Klein finally got to me, he entered the room without knocking, made some smart remark and then introduced himself. He diagnosed me with a "hernia" without even touching or examining me, and suggested I see a general surgeon. I left the office feeling more confused and uneasy than when I arrived. The next day, my pain was gone.. Certainly not a hernia. Today's appointment was regarding my 29 week routine check up. I pulled into the parking garage 15 minutes prior to my appointment and saw Dr. Klein arrive at the same time. I loaded up my two younger kids (3 & 1), checked in, went to the restroom, and waited. 20 minutes past my appointment time, I got up to confirm with the woman at the desk that my appointment was indeed at 10am(I was the only patient in the office and still hadn't been seen). She brushed me off and said they'd be with me shortly. I was eventually led back to the patient room, kids in stow, where I sat for an additional 40 minutes. By this time my 1 year old had started to fuss, my three year old was restless, and I was livid. I asked my 3 yet old to grab her things and walked out of the office without ever being seen by Dr. Klein. As I left, Dr. Klein rushed out of his office saying, "are you Nancy?", to which I replied, "yes I'm sorry I have to go, we will not be coming back here ever again". He then went on to say "I can see you now...". I will never return to this office. Again, I can not express enough my utter shock at the amount of unprofessionalism and lack of courtesy displayed by Dr. Klein and his staff. By the time I left, it was 11:15. I had waited for one hour and 15 minutes to be seen. No pregnant woman, especially with two young children, should have to be succumbed to this kind of behavior. Please save yourself a trip and look elsewhere for an OBGYN! I could only imagine what Dr. Klein would be like while you're actually in labor! read more

Would give no stars. If you decided to visit this office be aware that service is terrible. They don't return your calls, even worse, reception just ignores your calls. If you ask to pass a message to the doctor and nothing happens, just call from different line next time. Be ready to call 4-5 times to do simple things. read more

Truthfully my wife and I were very disappointed with this doctor. He was very insensitive, he did not explain the process with any level of patience and throughout our consultation gave the impression that he did not care about our situation at all. You guys should try RSC far, far better and much more professional and well organized. read more

I'm a patient of Dr. Klein for 17 years. He was one of my ob's during my high risk pregnancy 10 years ago and he is the one who did my hysterectomy surgery last month. He explained everything in details to me with all different options I had. Incisions are so little and almost unnoticeable. He has a very funny, quirky sense of humor, which might not play out with some people, so if you are not for that you will not like him, and it will be weird for you, but he is VERY caring , definitely a very experience and knowledgeable OBGYN. I would highly recommend him to any women. In addition, his office team of caring, professional women. They were incredibly caring, sensitive, helpful, and funny. Thanks for everything Dr. Klein and his office team! read more
