Dr. Lai is always very caring and professional. He is the best. I always trust him.
April 21, 2026
I was seen in a very timely manner the doctor is always quick and concise. Checks me, out then gives me an update on my condition. I enjoy the interaction between me and the doctor. Would highly recommend.

April 17, 2026
Awesome doctors
April 17, 2026
helped me.
April 17, 2026
I gave them my new insurance information for the supplement to Medicare. On my receipt it has my old insurance. Dr told me to get an Ultrasound but gave me no location for the test or phone # to call to set up appointment. Will reach out to them for more information
April 15, 2026
very helpful and understanding to my needs.
April 15, 2026
Lai and staff has always given me the best service Thanks
April 08, 2026
Thank God for Dr. Jason Lai. He is one of the best urologists. He goes the extra mile and I appreciate him more than anything. My family appreciates him for all the work he's done and will do and has done. We use him for our whole family. So, but my family is especially happy that He takes very good care of his patients like me since I'm an older lady. So my grandchildren, thank you too and their little ones. Thank you, Dr. Jason Lai.
April 08, 2026
Dr. Lai was very, very professional and very informative. I really appreciate him.
April 08, 2026
I am grateful to have access to Dr. Lai's services.
April 07, 2026
I would like to say that Dr. Lai is a wonderful doctor. He's very patient, very informative, explains everything to you and has a wonderful bedside manner. I'd recommend him to family and friends and (two names removed), the two girls, the nurses, the LVN, they're amazing. Thank you.
April 07, 2026
Dr Lai performed my prostate surgery more than 10 years ago and he was and still is top notch!
April 01, 2026
I felt confident with the doctor. He seemed quite knowledgeable. I will be returning to him. I would have appreciated if he'd have taken a little bit more time instead of being as rushed to give me a little bit more in-depth information. But I will be returning and everyone was very respectful. Thank you.
March 31, 2026
Everything went really well. Doctor listened to what I had to say. Personnel was really great. The only thing I had to wait a long time for my appointment. I would expect maybe two weeks, but not over a month.
March 25, 2026
I've been a patient of Dr. Lai's for many years and he comes straight to the point when needed. Just recently he recommended an MRI. No messing around and I love his demeanor and making you feel confident because he seems very intelligent. Thank you very much.
March 20, 2026
I was concerned when I received a letter from the office on the day before my scheduled appointment that they were unable to contact me and wanted me to call them immediately. I felt the right hand didn't know what the left hand was doing. When I called they assured me my appointment was still scheduled but someone didn't look at the notice under my name before sending the letter.
March 18, 2026
Seem much happier and friendly.
March 18, 2026
Yes, I think Dr. Lai is very knowledgeable. I don't think he spends enough time with patients. He does not fully answer my questions. If I have a question and have to call the office, it is very difficult to get a response from him. The message goes from the secretary to him and you never get a decent answer. So I find that annoying and I definitely think he needs to spend more time with patients explaining what's going on. Okay.
March 18, 2026
Very well.
March 18, 2026
Very professional!
March 13, 2026
Excellent service. Thanks
March 06, 2026
I really don't like to complain but not once, in over a year, has Dr Lai ever been on time. We are not talking 15 minutes late-more like 30-45 minutes late, every time. Not a single staff member came in to say the doctor was running late. This office has a history of computer problems and this time was no different. Additionally, he ordered a test and in review didn't notice that it wasn't done. It wasn't done because he failed to code it according to Medicare. He had not reviewed all my recent visits to other doctors. had he, he would have realized I just finished radiation for cancer
March 05, 2026
Dr. Lai was efficient and helpful during my brief office visit. It was expensive, even after a cash discount. The doctor ordered a metabolic panel, but I have had blood work recently. My insurance would not cover this new blood panel.
March 05, 2026
Every one office is very friendly and Dr Lai make me feel like a personal friend
February 24, 2026
the wait in the small room for the doctor is depressing. Should keep you updated how long it will be. Sit in a enclosed room for 30 minutes and you will catch my drift
February 18, 2026
It was very educational and informative
February 13, 2026
Dr. Lai is one of PIH's best Doctors! He has the absolute best bed side manner of any Doctor at PIH! He always is smiling and respectful when I have had to see him! I would definitely recommend him to any family or friend if you have an Urology issue !!
February 10, 2026
Finally I have a doctor that actually listens to me and the problem that I have had for years seems to be resolved
February 05, 2026
Felt rushed, like the provider and staff are racing out of the room from the moment they walk in. Provider had not reviewed patient's documentation/history before seeing patient. This feeds into the feeling of being so rushed he doesn't even have time to review history and makes me feel uneasy about trusting the provider with my care even though the provider appeared quite competent.
February 04, 2026
Yes, I was very needy to see Dr. Lai because of my condition, and I was very thankful that I got to see him. I was very impressed that when he walked in, he remembered me from, I want to say, 15 years ago and I was his patient. I was very impressed, and he was absolutely wonderful. I have another appointment, and I'm hoping to be able to get full relief for my condition. And I am thankful that I was able to see him.
February 04, 2026
Overall great experience. There was a long wait in the waiting room and also in the exam room.
January 27, 2026
Dr. Lai, Was attentive and explain things very thoroughly.
January 16, 2026
I was treated very well. I liked the doctor, but I waited a long time. I didn't get out of there for a long time. I thought they had forgotten me.
January 02, 2026
Dr. Lai is nice enough but he kept interrupting me when I was trying to tell him what I had or was experiencing. He made me feel rushed and I didn't get to share or ask everything I wanted to. I feel the information I was sharing was important and I don't feel the concern was there. Additionally this is about the office. The walls are paper thin. I could here his conversation next to my room. I tried not to listen as to not invade the patients privacy. But I was able to hear the doctor giving the patient a cancer diagnosis. The walls need to be addressed to protect patient confidentiality.
December 31, 2025

December 16, 2025
Very nice doctor.
December 16, 2025
Yes, I had a surgery and Dr. Lai, Dr. (name removed) both involved. They kept me informed. Everything went as best as it could possibly go. And I'm very happy with the whole experience. Thank you.
December 16, 2025
Always professional staff at PIH.
December 09, 2025
Called to do a scheduled appointment and they gave it to me a month later. I did it online and I got it a week later. Seems like kind of a disrepancy to me.
December 05, 2025
I need a little more time dedicated to listening to the symptoms of the illness I have.
December 03, 2025
Dr. Lai is an amazing urologist. Everyone should go to him.
December 03, 2025
For me, everything was excellent with the doctor. I already know him, he performed surgery on me before, and for me he is excellent. Very good. Thank you.
December 02, 2025
Very good experience
November 28, 2025
The doctor was very kind and thorough. I really liked him. I would refer him to anyone, but especially my family. Thank you. Bye-bye.
November 25, 2025
Great doctor and staff.
November 19, 2025
Yeah, no, it's been a very nice experience. I have seen the guy before and he's very helpful. Let's put it that way. Very, very helpful when I need it the most. Like, for instance, the shot that he's been giving me now instead of all the medicine that were very expensive, even though I do not pay, but insurance pays too much. To me, it was too much money. $2,700 for 30 pills. And I'm glad he listened to me and he did pretty good, and I got the first shot yesterday. Thank you very much for your help. Bye-bye.
November 18, 2025
Very personable, listens and treats you with respect
November 14, 2025

November 11, 2025
Nothing, everything's fine.
November 07, 2025
Office Staff and Medical Personnel were very respectful and professional.
November 05, 2025
Dr. Lai is very nice. He gives you plenty of time to talk to him and he explains to you very well. From the front office to the nurses in the back, they are very polite, very nice. You're really nervous when you're going in like me and they make you very comfortable the same way as Dr. Lai. He makes you very comfortable. And believe me, I have told so many people about him and the office and they are seeing him, even my husband. And I'd like to just say thank you to all of them for being so nice and understanding.
November 05, 2025

They all did a great job!
October 10, 2025
Dr. Jason Lai is a excellent Urologist
October 10, 2025
Dr. Lai is an outstanding physician and long-time personal doctor. This time the doctor and office were extremely busy and overbooked causing a very limited (a few minutes - less than 5, for personal time. Not the doctors fault. PIH should address the time a patient is checked into the patient's exam room and the time seen by the doctor. This time, that wait was exactly one hour, however I was told it would be minutes following taking my vitals. That is a long, lonely amount of time to sit and wait without any kind of update as to the delays.
October 08, 2025
Great experience, as was expected.
October 07, 2025
would like to say this is (PHI removed) my recent visit and on all my visits. The doctor is very professional and Dr. Lai is very kind and very, very patient. He's a wonderful doctor. Thank you.
October 07, 2025
Definitely a positive experience.
October 03, 2025
My appointment went very well.
September 30, 2025
I can see that they are well organised.
September 24, 2025
Easy no long wait and professional
September 24, 2025
The doctor was very helpful, caring and understanding to my needs great job
September 19, 2025
I was scheduled for an 8.45 appointment, which is relatively a very early appointment. However, at 8.45, I was not called. I was not called until 45 minutes after my scheduled appointment. I was not called until 9.30. So, it's not acceptable that for such an early morning appointment the doctor is running, 45 minutes late. If I'm late for my appointment, you will cancel me. But if you're 45 minutes late, I have to be patient and understand. Not acceptable.
September 19, 2025
I thought that Dr. Jason Lai was professional, was courteous, explained the different options, and allowed me to input my feedback, which I thought was important. And so moving forward, I am looking forward to having the rest of this medical condition taken care of and resolved. I trust Dr. Jason Lai. and I am happy to be under his care.
September 17, 2025
Great doctor! Dr. Lai. But found that waiting for 20 min in the lobby and 40 minutes in the room was unacceptable. After making the front desk aware of the situation, doctor came within 2-3 minutes. I was on time but waiting for an hour is not right.
September 17, 2025
Dr. Jason Lai has been an excellent doctor and I've been under his care. I would recommend him to anyone. He's a good doctor and PIH is lucky to have him. God bless him.
September 17, 2025
Dr Lai is a wonderful Dr Lai always a pleasure
September 15, 2025
Dr. Lai is amazing. He always listens to me and he explains everything to me in ways I can understand. He is kind and very professional. I have recommended him to my friends. My procedure went great. Thank you Dr. Lai!
September 12, 2025
Dr. LAI has saved my life more than once & Is an excellent doctor. (PHI removed)
September 10, 2025
I've had Dr. Lai for a few years now, and he's very trustworthy. I respect the word. And not only does he let me ask questions, he'll ask me some questions just to make sure. And always gives me enough time in case I forgot something and I go out the door and go, ah, I should have asked him that. So yes, I highly recommend Dr. Lai. Thank you.
September 10, 2025
Dr. Lai is very pleasant to deal with and is very thorough.

August 05, 2025
I deeply respect this Dr and his staff.
August 05, 2025
Dr Lai and his staff and associates have been very forthcoming with regards procedures, tests, their results consequences and prognosis, which is most reassuring.
July 23, 2025
Good experience, would recommend
July 16, 2025
Yes. The second question was, was I able to make an appointment quickly, I think. I pressed two thinking it was yes, not really realizing it was just somewhat. So I should have pressed a number four all the way across. I had a great experience with Dr. Lai. Thank you.
July 15, 2025
All good experience.
July 11, 2025

June 10, 2025
Dr. Lai is very professional
June 10, 2025
Thank you Dr Lai
June 06, 2025
The appointment took too long to see the doctor, and then it took even a little longer to actually see the doctor.
June 06, 2025
Dr. Lai is always very professional in his interactions. He doesn't just 'treat' symptoms but asks questions that aim to find out the source of problems and solve them. He is a definite asset to PIH!
June 03, 2025
Great attentive and thorough care.
June 02, 2025
Excellent service and friendly attention
May 29, 2025
Dr. J JASON is a very nice and well respected doctor listens and explains things really well. I love talking with him.
May 28, 2025
The most dilapidated and depressing office space I have ever set foot in. More like an infirmary than a doctor's office. Waited for over 30 minutes in a small dingy room with the blinds drawn. Vitals not checked. No physical exam. I don't know why this could not have been done over FaceTime?
May 27, 2025
Yes, the doctor was good. Without a doubt, extraordinary, but is in a rush on the daily and well, as an elderly person, I sometimes can't understand and have to ask for them to explain things again and he does explain it again, but does it in a rush and I would like for him to spend more time with the patients so that we can full understand and leave feeling satisfied. He is a good doctor, without a doubt, but the care in the office isn't very good, for the same reason that they are in a rush and sometimes (unreadable) and they get upset and that is the only thing I don't like. But like I said, the surgery and everything was good.
May 27, 2025
The care I was given was fantastic. Thank you.
May 23, 2025
I ordered medicine and I'm having a difficult time getting it.
