I have been going to Dr Tsai for semi-annual checkups for several years. Dr Tsai is an excellent, knowledgeable, experienced, skilled physician whom i highly recommend. He is not too old and he is in the prime age of his medical career and knowledge. He has helped me greatly improve and keep all my age related symptoms within the desired range: cholesterol, blood pressure, glucose level etc. He has a very friendly manner, easygoing interaction with patients. Best of all. the waiting room is never crowded. His office works efficiently. so i have never had a long waiting time. His appointments are always right on time. True story. After every lab blood test, Dr Tsai always takes the time to promptly follow up with a personal phone call to give me a quick summarization of the test results. read more

Several members of my family are all patients of Dr. Tsai and I can say wholeheartedly that he truly is the best doctor. While we were initially disconcerted by the introduction of his CAP membership fee, we quickly realized it is absolutely worth it due to the unparalleled level of wonderful care Dr. Tsai provides. He genuinely looks after my Grandma, and always takes his time to follow up with my husband and I. We all feel blessed to have found him and can't recommend him highly enough! read more

Got billed after canceling the 500/year membership a month before the cycle. I even received a canceling confirmation email, but I still got billed. read more

He is so compassionate and thorough, I appreciate the care he provides me. The PA, Tina, is also excellent and takes great care of patients. The whole team is detail oriented, always on time and so very polite and attentive. This is a really well run practice by a caring team. I do pay the annual fee, and it's well worth it to be able to get appointments when I need them. His follow up is the best. read more

He has been our family primary care doctor over 12 years. He is a great doctor who listens and easy to talk to. He gives us guidance with care. We are so thankful to have him as our primary doctor. read more

Understanding, educated, always returns calls the same day! Does not rush, acknowledges the human condition. Basically, he's an excellent doctor and compassionate, which is a rare and valued quality. Thank you Doctor read more

I chose Dr. Tsai as my primary care physician when I moved to the area almost two years ago. As a healthcare provider myself, I am very particular about whom I see for my own care. I have seen Dr. Tsai three times on routine visits, and on another occasion, I received very fast telephone help with an emergency. He is warm, friendly, knowledgeable, thorough, and responsive. He listens well and explains well. In my opinion, these are all essential qualities for a provider. His office is neat and clean. He and his staff are respectful of my time--they stay on schedule, and I have never had to wait any significant amount of time in the office. As concierge fees go, his are the most reasonable I have seen. I suspect that making his practice concierge has allowed him to deliver the kind of care he does, and it is certainly the kind that I, as a patient, want to receive. read more

I called to make an appointment with this doctor since they were listed as in-network with my insurance. However, when I spoke to the front desk, I was informed that I'd need to pay a $500 annual "membership" fee just to be seen. This fee supposedly grants access to same-week appointments and the doctor's network of specialists. Since when does it cost extra just to schedule an appointment or be referred to specialists? Talk about catering to the rich. This feels like pure greed. Don't waste your time or energy on this office. read more

Dr Tsai is so friendly and professional for my first visit ... he truly cares and willing to listen So grateful the Lord Brought him to my life because I don't like to take medication ... but his professional opinion brought a lot of comfort to me Thank you read more

My neighbor referred me to Dr. Tsai with the additional comment, 'Of the ten people I referred to him, every one wrote me a thank you.' I wrote my neighbor. to include me as the 11th referral that was very, very pleased with Dr. Tsai. He has a warm, engaging personality as well as the impression of conscientiousness & competence. Meeting him for the first time today was a very delightful, very professional experience. I would recommend him without reservation to anyone looking for a primary care physician. read more

How about 10 stars! I was a patient of Dr. Tsai for many years. He's a great doctor and very thorough. When he went to concierge, I decided to go to another doctor as I didn't want to pay the fee. However, while the other doctor wasn't bad, the other doctor was challenging to reach for prescriptions. My pharmacy would have to reach out several times, etc. and just not as thorough as Dr. Tsai. So, I was having some symptoms over the last few days and I decided to go ahead and pay the fee for Dr. Tsai. For any of you that are considering paying the fee, you should do it. It is worth it. Not only did I get a next day appointment with Dr. Tsai when I called yesterday, he found that I was in Afib and immediately called a cardiologist and asked them to get me in today, which they did. I am so appreciative of his extra help. Doctors here can take a month or two months to get in to see. Now, I can get the process started and find out what's going on. read more

I was so looking forward to seeing this doctor for the first time. I made an appointment for my husband and I months ago and blocked time out of our busy work schedules. Prior to making the appointment I made sure that Dr. Tsai was in network with our PPO. He was. I even called the office the morning of the appointment to confirm the time and parking situation. Upon check-in, I was told that our PPO would not be billed and instead we could proceed with the new $500 yearly membership if we wanted to move forward with Dr. Tsai. I was upset and asked why I was told about this before wasting my time. The receptionist said that they don't have enough time to call everyone. I called the morning of the appointment and she had an opportunity to tell me then but she didn't. Instead I wasted our time. This is an incredibly inconsiderate and unprofessional practice. The doctor himself might be great but not warning people of this change in policy beforehand is just plain wrong. read more

This Dr. just started to charge a $500 yearly fee per patient. So if you have a family of 4 that's $2k a year! He's already billing insurance. How much more money does he need? Maybe he's just pricing out us normal folk and only wants to deal with a certain type of clientele $$$$. Greed overcame this guy. read more

Honestly, writing this review makes me sad. My entire family has gone to Dr. Tsai for years and he is an excellent doctor, but his practice now requires a $500 per year membership fee to get any sort of care on top of whatever insurance charges. How can working people who already pay high insurance premiums and deductibles be expected to fork over money like that to just get an annual physical and maybe visit once or twice a year for an illness? Pure greed as far as I am concerned and he is losing 5 patients of more than 7 years as a result. read more

So, I just received an email today from Dr. Tsai's office about a $500 fee that all patients need to pay to retain him as their doctor. First of all, what? I've never heard of this being done before. Second, as I'm sure all his patients know, he's never available for appointments in any sort of reasonable timeframe. Got a pressing issue? He'll see you in 6 months. (​I will add that his PA is almost always available and she's better than most doctors I've had before.) Instead of doing the sensible thing like most other clinics and cutting new patients off ages ago, he's now ​trying to price people out. This seems extra scummy for a doctor's office and I can't see how this is going to go well for him. The cherry on top - The ​email had the audacity to mention that the response to the new policy "has been overwhelming." I don't know of anyone that would be happy to pay a membership fee to have a doctor, so I'm assuming that means overwhelmingly bad. This dude used to have a solid 5 star Yelp rating, and I have a feeling that's quickly going to change. read more

Charging a membership fee of $500 per year is insane. I am so disappointed that we cannot see him anymore but more disappointed that he only cares about greed. Who could afford and who would pay for this? read more

First timer I went here I didn't even saw the DR which I dislike a lot! They send me to a different floor to see the nurse. Had no idea and was so confuse. Got my blood work and Dr did call me and everything looked good. Second time: Got blood work done Didn't see Dr My test result are in my quest account but haven't heard from Dr at all Changing Dr since I feel like cattle $$$$ read more

Great, knowledgable and attentive doctor. He is very kind. He always has good advice. He is now a concierge doctor.

Friendly, efficient, thorough, and overall an amazing start to finish process; from setting the appointment, to checking in, meeting Dr. Tsai (arguably the most knowledgeable and kind Dr ever), finishing checking out, and even the follow up from the Doctor himself. He clearly engages with the local community, and seems to be doing God's work in this way. I searched for a LONG time for a General Practitioner or Family Medicine doctor, but Dr. Tsai's office was the one for me. He is a good man and one of great character. He was helping older women translate in the lobby, and helping 30yo's like me, and even younger patients. That means so much to see the diversity and heart that goes into the carefully curated experience in Dr. Tsai's office!!!! So glad I chose him! read more

Very efficient, very thorough. One of the few last private practice doctors around if you don't want to go to a hospital owned doctor.

Dr Tasi was my Doctor until he decided to take his office to concierge and charge you $500 a year to use him. All the reviewers here after he went that way in 2023 are very disappointed as I am. He is a good doctor but going to the cash scheme has out priced many of us and our family members. read more

The office imposed a $500 annual membership fee for just some sort of routine check which is ridiculous.

Today I had an appt. With Tina ... Dr.Tsai's nurse practitioner. This was my first visit so we needed to cover my health history / medications and complete a pre- op physical for an upcoming surgery. I was amazed at how knowledgeable organized and professional she was. Quite a skilled nurse, I'd say ! read more

Dr. Tsai is an incredible physiscian. Very knowledgeable, thorough and caring. He takes a very genuine interest in each of his patients and spends as much time as necessary with each appointment. Also, if you have lab tests done he personally calls witht he restults. Simply an amazing person. I only wish that I had found him many years ago. read more

Most inefficient and disrespectful office! The medical assistant measured my height height facing the machine while half my feet were hanging off the scale! Then the manager tried to run my credit card for their biannual payment and was unsuccessful! My bank said there must have been complaints against the vendor that's why it was turned down due to possible fraud. Meanwhile, these disrespectful people removed me from the exam room into the waiting room because the payment wasn't going through! Well you be the judge? read more

I can't say enough about Dr. Tsai's "bedside manner", performance and empathy as a doctor. His follow through is impeccable, personality a 10+ ! I have never had a doctor that I trust more for competence and reliability. My husband and I are so happy that we found him. read more

Been coming to him for years. All of the sudden it's a $500 "membership fee". When did his office turn into a gym? In addition, last two years, he wouldn't even see me, they passed me along to the nurse practitioner who is an airhead. Says I gained weight and it's concerning to her, but paid no attention to the fact that it was muscle weight and not fat. read more

this place now requires current and new patients to pay a $500/year "membership fee" for administrative costs (not covered by insurance) to get service. LMAO!!!! what a joke... never heard of this. read more

Just when I thought I found the best MD which he is a great doctor BUT I find out now he has a membership fee of $500 dollars a year in addition to charging the insurance and co pay . I'm not joining a gym a physician shouldn't be charging a membership fee for sling his job . If u can't manage all the pts just say not accepting new patients or offer that to ur new patients not to you're existing patients. Very frustrating and disappointing. Hate to leave but gauging patients is not acceptable. read more

I agree with the other reviewer. I have been going to Dr. Tsai for years. I really like him, but recently I have been seeing extra fees. Now there is a $500 membership fee just to pay for his administration. I cannot afford another $500 a year and I can only get in to see him once a year!!! I will have to another great doctor in Orange County now. He is not only losing me but my family members. I agree it's pure greed too!!! read more

Awful employees that don't do their job. Good luck having any request fulfilled. His wife runs the show and they now use a membership service and run it like some private medicine service without any of the benefits. Using sales strategies such as telling you you should soon pay for the membership due to being at 90% membership capacity. read more

Always comes through for me!!!! EVEN ON WEEKENDS:) He has been my PCP since 2012 and honestly he is one of the best doctors. Thank you Dr. Tsai read more

My husband and I are seniors and have picked up many specialists along our path. We were lacking the master to oversee the specialist and catch the areas of our health that fall through the cracks. Dr. Tsai is easy to talk to, has strong communication skills and a great bedside manner. He calls us personally after lab work to discuss results. His schedule gets pretty busy and you may need to wait a couple months for a appointment. But Wait ! He has that covered as well. He has a PA that sees patients when you just can't wait. We found him through a nurse that treated my husband whIle in Chemo Therapy. Thankful we did. What a great forum Yelp provides ...... read more

Ok once you see the pa and dr but not very easy to contact them or expect follow up. Just to call you have to jump through a bunch of voice menus even though it's s so small office. No email on their website either. read more

Amazing care with an amazing doctor, I would highly recommend this clinic for anyone looking for a care provider who actually cares about you. read more

My amazing doctor that I went to for over 15 years stopped her practice and went to Kaiser. I researched, and found great ratings for Dr Tsai. My husband and I went to him last year for our annual physical. He gave much attention to my husband, which was awesome. Me on the other hand, he spent about two minutes with me, said I looked healthy, and acted like I didn't even have an appointment. I told about a lump on my back, and he just blew it off and told me to get checked by a specialist. He didn't look at it or feel it. His office also didn't want my health history from my previous Dr, which doesn't make sense. how do you know what prescriptions I take, and what conditions I have? Later, I called in to ask for a refill on a medication, and I was very specific for an inhaler for my asthma, they gave my pharmacy a liquid medication rx for a nebulizer. when I called back and said that I need the inhaler and gave them all the information again, and they said they would take care of it, they never called it in to my pharmacy. My husband wants me to give him another try. I'm debating it. read more

I worked in the medical field my whole life so I'm picky about my doctors. Dr. Tsai treats me with dignity, caring and compassionate. Listens to concerns and answers questions. The office is clean, the staff are friendly. I would recommend him to anyone. I have been going to Dr. Tsai now for several years and my opinion has only improved. Excellent, caring physician. read more

I have to agree with all the other reviewers that I'm extremely disappointed with his new $500 a year "membership fee". I had been a patient of Dr. Tsai since 2020. However after my last visit in June I was notified of the $500 membership fee. I was disappointed but still considering it since I did liked him.... However, last week when it was time to renew my medication, I got a message from the pharmacy that the Doctor didn't approve the refill even though I had 3 refills left. I called the office and they told me that if I wasn't planning to sign up for the membership that they would approve the refill. That rubbed me the wrong way and now for sure will look for a new doctor. If you see your doctor twice a year, that's $250 a visit plus whatever they charge your insurance. It doesn't pan out as the average cost for a regular doctor's visit without insurance is about $150.... No Thanks! read more

My husband and I cannot say enough about Dr. Tsai. He is always concerned about issues we have and listens carefully to what we have to say. He even called us In Costa Rica personally to remind us to come in for Bloodwork upon our return. Dr. Tsai represents everything a physician should- caring, highly intelligent, great listener and a wonderful doctor who points you in the right direction for tests. We live in Palm Desert and still drive in to see Dr. Tsai. He is the best!!!! Jill and Barry Smith read more
