Dr. Lee Tat Chan has been an exceptional family doctor for my elderly family member. He treats his patients with genuine care, patience, and respect--qualities that are so important, especially for seniors who need both medical attention and emotional reassurance. He takes the time to listen carefully, explains medical conditions in simple terms, and ensures that my mom fully understands her treatment plans and trade-offs. His approach is practical and never rushed. As a good listener, he balances professionalism with a personal touch that makes patients feel valued and heard. read more

Do not go to this doctor. My mother has been a been a patient for many years. She made an appointment to see the doctor about a cold, When she arrived at the office they refused to allow her to see the doctor. She had no fever, just a cough and she had all her Covid vaccine proof. She wanted to see the doctor about her cough. They told her to go home and take a Covid test. If a doctor cannot be seen because of a cold cough, what is he there for? I have brought my mother to see Dr. Chan once before and he has very poor bedside manners, very impatient. My mother is a little hard of hearing and began yelling at her. She is a little hard of hearing but not deaf, we had to ask him to stop yelling at her. I would never recommend this doctor to your loved ones. read more

Dr. Chan is the best doctor I have ever had. His office is very quick to answer the phone, and I was often able to speak directly to Dr. Chan to ask questions before scheduling an appointment. Scheduling appointments with him is very easy and I was often able to go in the following day or week. He is a great listener and I found him to be very friendly and amiable. I recommend choosing this doctor if you can. read more

Probably the rudest receptionist i've ever talked to. didn't make an appointment.

I was a patient at this practice for many years when Dr Wellman Tsang was my PCP. After he passed, I saw Dr. Chan. I had never met a doctor who was dismissive and uncaring before. He didn't provide the care that I thought me and my family deserved, so we left and found a new family doctor who is amazing. I requested to have my medical records sent to my new doctor so that he can have my complete medical history. I brought the request in person to the office; a month later, the request still wasn't fulfilled. I left 2 messages and never got a call back either time. Please see Shaun C's review from 10 months ago. Every detail is correct. That person who had to suffer the whole month of October 2019, because Dr Chan could not correctly diagnose a liquid-filled lung, was my mother. She passed in October 2020. read more

I have been a patient since 2018. From 2018 - 2020, I just had some blood work done. He never called me back regarding the results. One of them show high bile count. Then in June 2020, I had pain in my right side. I went to the ER and they discovered kidney stones. I had to get an pre-op exam from him to have the stone(s) removed. It was not a pleasant visit. We argued and talked so loud that others in the office heard us. He dismissed lots of my concerns and told me that I wasn't listening to him. It was really him wanting to talk over me. Four months after the operation, I developed the same type of pain and went back to see him. He told me that I was tensed and probably had stomach issues. He didn't suggest any X-rays or ultrasounds to confirm his "diagnosis". He prescribed some gas relieving medicine which is not helping. I had blood work done this week and is waiting for him to call about the results. If I don't hear from him, I will call him next week to see what the next step is. Stay tune ... read more

This was my aunt's doctor until about 2 months ago and since she speaks very little English, I felt I really needed to share her experience with Dr. Chan, as he almost cost her her life. Seriously. I go into detail below, but essentially this "doctor" failed to diagnose her, let alone even test her for anything, or treat her with respect, AND SHE HAD STAGE 4 LUNG CANCER. How any respectable doctor misses lungs filled with 2L of fluid is beyond me. Last year, my aunt went to Dr. Chan (her former primary) late October because she was having difficulty breathing and constantly coughing. It wasn't when exerting herself, it was constant not being able to breathe in completely. He listened to her lungs, said they sounded clear, that she probably had acid reflux and prescribed an antacid. She sees him again within a few days after taking the antacid because it worsened; she couldn't breathe fully and could barely walk 15 ft. He basically wrote her off, telling her that that was normal, but switched antacids and told her to go to cardiologist. Didn't explain why to her. Listened to her lungs again and didn't offer an xray. She tells him that she's experiencing pain that shifts around her body; he examines her upper torso, tells her nothing's wrong and that she should take anti-anxiety medication. That is absolutely ridiculous, this tells you so much about how he practices medicine; he didn't believe/take her pain seriously and writes it off as anxiety. Terrible. She goes again for a third time (3 visits in 2 weeks) because it's worsened even more. She literally couldn't walk more than 5ft w/o having to stop and is kept up all night coughing. He listened to her lungs AGAIN and said they were CLEAR. After this, my aunt asks should she get a blood test, to which he responds, "you just had your blood examined 3 months ago, there wasn't anything wrong. I really don't know what's wrong with you/how to fix you" (translated from Cantonese, with attitude). ARE YOU SERIOUS!?! YOU'RE SUPPOSED TO BE THE DOCTOR. IT'S YOUR JOB TO FIGURE OUT WHAT'S WRONG WITH YOUR PATIENTS! My aunt then asks could it be bronchitis or pneumonia? To which Dr. Chan says "no, your lungs sound really clear. But I can't really do anything other than order you an xray." So, she has an xray taken and lo and behold, there's a shadow in her lungs. He calls her up to tell her about the shadow and instructs her to now go for a blood test to confirm the presence of fluid in her lungs (guess he should've listened to her) and get approval for a CT scan. That night she can't take it anymore as she can barely breathe just resting and goes to the ER. They immediately take an Xray and see that her lungs are full of fluid. So, they keep her overnight and the next day immediately drain her lungs pulling out 2 liters of fluid. TWO LITERS!!! AND DR. CHAN SAID THEY SOUNDED CLEAR AFTER LISTENING 3 TIMES! The ER sends the fluid to be tested and that, combined with the xray is what gives her the stage 4 lung cancer diagnosis. Her daughter calls Dr. Chan to discuss the diagnosis and kinda calls him out on why he didn't hear the 2l of fluid (politely, just asking why). This leads to him being very short and rude with my aunt on their next phone call. She has since switched primaries and is now very happy with her current doctor who actually cares about her. There's so much in this experience that is so unacceptable and I can't believe he's still practicing. If you have a patient that's coming to you for help/relief from severe pain and shortness of breath 3 times in 2 weeks after typically only coming in for annual physicals, that should tell you something. To not take her seriously, not make any real effort to properly diagnose her, when she was clearly suffering (from stage 4 lung cancer!) shows me a clear lack of commitment to care. Dr. Chan was absolutely useless as a doctor and did not contribute in any way to her eventual diagnosis. He's lucky she was able to get a diagnosis elsewhere and is currently undergoing treatment. read more

I've had good and bad experiences with Dr Chan as my PCP. When I first started seeing him in 2000 he was really helpful. He spent a lot of time with me, answered questions, listened and let me be proactive in my health care. But then in 2005 I got sick and he was unable to figure out why. After a while, he decided that my illness was all in my head and stopped listening and stopped reading the reports that my specialist sent him. I still strongly believe that he is/was a great doctor for the care I received for over 5 years. Another plus is that he returns calls within a half day when he is in the office so I wasn't stuck next to the phone for hours/days waiting for a return call. read more

These are first impressions as I just became Dr. Chan's patient after moving to SF and the Richmond District. He was very thorough and focused on wellness, not just ailments, as other reviewers have noted. I liked him as a person, maybe not medically significant but I feel we will be able to communicate better because of it. I was disappointed by a couple of moments in our discussion. One was when he scoffed at the diet my previous doctor had recommended to me and that has worked well for me. The other was when he asked how I chose him and I mentioned an online review site (not Yelp), which he clearly considered a stupid way to choose a physician. Time will tell whether I conclude, as one other reviewer did, that he isn't willing to listen to me or other doctors I'm seeing. I care about this issue because I stayed with my DC-area primary care physician for 30 years precisely because she treated me as an adult participant in my medical decisions. I'm not willing to be talked down to as was perhaps normal for doctor-patient relationships in the past. read more

I have been a patient of Dr Chan's for 11 years. In that time I have found him to be attentive, dedicated and careful in his treatment of me. His office has also been very good about squeezing me in when a sudden illness or condition has arisen. I think what I like most about Dr Chan is that he listens carefully and considers what I have to say in making a diagnosis or suggesting a treatment. It's that somewhat rare situation where you feel like your doctor is also a partner in helping you best manage your health. read more

Dr. Chan is currently my mother in law's pcp because her old pcp is retiring from the practice. My mother in law recently suffered from a minor stroke & was finally discharged home. During her hospital stay, he told the hospital staffs he'd make his visit to check her condition but NEVER showed up. When she finally went home, her blood sugar was outrageously high. Dr. Chan specifically told both my mother in law & my sister in law he'd adjust her insulin dosage & reduce the number of injection. Guess what? When my sister in law picked up the prescription, the medication was totally different from what he had told them verbally. She double checked the prescription & he wrote the wrong dosage. Right away, she calls him to verify. His response was "between 35 units & 25 units is only 10 units different & will make no difference if she injects 35 units instead of 25. But let's try 25 units for now & adjust later as needed." Ok, he made an error & did not even admit or apologize. 2nd, he refused to write a prescription for the meter test strips because he said her insurance only allows 1 test strip usage per day. How pathetic does this sound? I've never heard such thing that insurance only allow diabetic patients to test his or her blood sugar 1x per day only. All I can say is he's a terrible doctor & if anyone is looking for a one, he's definitely not who I'd recommend read more

Dr Chan Lee Tat is the most compassionate and thorough doctor! He is always thinking about what's best for his patients overall vs just treating symptoms. He is my 84 year old auntie's doctor and treats her with extreme care and compassion. We feel very fortunate that my aunt has Dr Chan advocating for her health and quality of life. read more

This doctor Lee T Chan is terrible. Not only is he unprofessional in dealing with my family, he also does not do his due diligence when it come to patient care. He is suppose to review results before a procedure and neglect to do so in our situation. How hard is it to review a lab result?? Exactly! When questioned about it, He pushes his responsibility as a "Primary" physician to other specialist doctors to do the work and dodges the question. Then he ends the conversation by having up the phone. So unprofessional!! Who tells their patients why you have so many questions and ask am I the doctor or are you the doctor? Taking advantage of elderly that do not speak English well is not a nice look. He takes no responsibility and I absolutely agree with the "precious a." [ll I can say is he's a terrible doctor & if anyone is looking for a one, he's definitely not who I'd recommend] read more
