September 02, 2022
Hi, this is (PHI removed). Actually, I visit on 2nd September. And I really like the doctor. He spend a good time. He... he listen me... listen to me very carefully. He understand everything. He check my (INAUDIBLE), what's going on. So he's really good. Thank you so much.
September 01, 2022
Dr. Lai's extremely knowledgeable, professional, and efficient when it comes to health care of his patients. We have extreme gratitude for his knowledge and his talent as a doctor. He has not only serviced my mother, but my father and my sister. We will highly recommend his office and his professionalism to any patient for (INAUDIBLE)...PIH.
September 01, 2022
Yes, I made a mistake in the first question asked. I should be... it should be yes, number 4. I think I pressed one by mistake. Outside of that, everything was fine. Thank you very much, goodbye.
August 30, 2022
Office could be much cleaner
August 30, 2022
Very Courteous and professional staff , well experienced to explain about the treatment needed and the follow up. Thanks
August 30, 2022
Great doctor
August 29, 2022
Difficult to answer recommendation questions to family and friends since COVID started. Not seeing and not engaging in such dialogue. Dr. Lai explained the lab values for my understanding; I'm pleased.
August 29, 2022
The doctor was great explain everything.
August 25, 2022
August 23, 2022
Excellent Dr. truly trust his care & knowledge in keeping me well. I feel his care about my health is keeping me at my healthiest. Thank you!!!
August 23, 2022
Overall a very professional experience. Doctor and staff are very capable.
August 22, 2022
first visit so hard to know answers fully
August 18, 2022
Still not interested in any more of these surveys. Just leave me alone, please.
August 18, 2022
The office is always cleaned and the staff is always polite professional and knowledgeable about my wants and needs
August 18, 2022
Great doctor. Nice staff.
August 16, 2022
There were about 25 people scheduled at the same time which doesn't give the doctor enough time to answer my question or even do a physical exam. If I am going to a specialist I would like to spend a little more time talking about my issue.
August 15, 2022
Long wait. Shortage of Dr. On my appointment time. A/C in that building is not adequate for the volume of people using the space.
August 12, 2022
A more complete explanation was in order. I have almost 50 years of experience in the allied health field and I had to fill in blanks and make assumptions. My concern would be for patients, especially elderly, that don't have that ability or understand the questions to ask. A more gentle hand and conciliatory bedside manner would have helped.
August 10, 2022
The waiting room is far to small for the number of patients that are scheduled. There are 20 chairs in the waiting room, none of them had the recommended 6 foot Covid spacing. All seats were filled with patients waiting to see a doctor. There was no separation of seats in the waiting room, only 2 seats had more than 3-4 ft separation from other chairs. There were 10-12 additional people waiting in the hallway. My wait was approximately 1 hour & 45 min. Aside from these health precautions, the doctor and staff provided professional service.
July 28, 2022
I expected an exam.
July 28, 2022
I pressed the wrong keys. In the beginning also (INAUDIBLE) at the very end. (INAUDIBLE)rate this provider as super duper excellent. In all categories. I'm sorry for the misunderstanding video instructions. Bye.
July 28, 2022
Dr Jason Lai very good dr.
July 22, 2022
(INAUDIBLE) looked very professional and nice and friendly.
July 19, 2022
i had an app for dr jason for may 24 it take me 2 mo to see dr jason july 19 front office need help. i have no problem with dr jason good dr. super/
July 18, 2022
Dr. Lai is a wonderful doctor and I trust him 100% with my care.
July 15, 2022
One of the office staff at the front desk was very rude and not helpful to all the senior patients. Of the time we were waiting to be seen in the waiting room, she was on her personal phone texting for at least 50 minutes. She is the staff member with a large tattoo of roses around her wrist.
July 07, 2022
Dr.Lai is an amazing doctor. He shows compassion and really cares about his patients. I can't just can't say enough nice things about him. Thank you.
July 07, 2022
Too early to give a report. Everyone seemed helpful but long wait to see the Dr.
July 07, 2022
I waited for a half an hour for the Dr. To see me. Too long
June 30, 2022
Quick and fast
June 28, 2022
Delay in getting in to see the doctor was due to a staffing meeting that morning. It was about a 40 min wait.
June 28, 2022
The staff was very nice, got me in really quick, and the doctor listened and answered all questions, and helped above and beyond.
June 21, 2022
I called multiple times and left messages to call back, no one answered and no call back at all, no matter how busy you are, you need to return patient's call , we called for reasons.
June 17, 2022
I was very upset and anxious coming into the appointment. When Dr. Lai came in and was talking to me about the procedure and explaining everything that was going to happen and... and answering questions and... and all that, I instantly felt much more at ease and figuring that I really trust this doctor to give me the best... the best treatment possible. Thank you.
June 17, 2022
Dr. Jason Lai I believe is a excellent urologist. I have only had positive experiences with him treatment and expertise.
June 10, 2022
Dr. Lai is an amazing doctor. He's knowledgeable, personable, and compassionate.
June 07, 2022
Sr. Lai explains things thoroughly and also explains the symptoms, very professional with a good attitude.
June 06, 2022
i was satisfied with the appointment
June 06, 2022
Explained results in language I could understand. A fine physician
June 06, 2022
Seems he was in a hurry. He was in and out, less than 10 minutes. He didn't explain things thoroughly. He send me to do some test and come back in a month. I had to ask if I should follow a certain diet, exercise or take certain medication.
June 03, 2022
Doctor is outstanding. His office staff are not
June 02, 2022
I'm very happy with the service by Dr. Lai and I would recommend in to family and friends.
May 31, 2022

My first visit no one spoke to me no greeting at all, not at all friendly, doctor was ok , we always get good service with PIH first time this has happened.
May 27, 2022
Office staff was great, wait time was about 15 minutes, the doctor explained my issues and provided me with a plan to heal .

He is a great listener and truly cares
May 24, 2022
Very good...
May 23, 2022
We were extremely impressed with Dr. Lai. He is exceptional. We were more than happy with his responses, the way he is treating the cancer that has grown in my body. I am so happy we were able to get someone so intelligent and so easy to deal with. Keep that that type of guy on your staff, please. He's wonderful. Thank you. Bye.
May 23, 2022
Provider to spend adequate time with clients.
May 20, 2022
I felt like Home. Thanks.
May 16, 2022
Dr. Lai explained to me the different options I had and explained them fully to understand what was going to happen during the procedure, which I appreciated.
May 16, 2022
Good experience. Dr. Lai does an excellent job taking care of me. Office staff & nurses on top of things.
May 10, 2022
The doctor was great
May 09, 2022

May 05, 2022

April 28, 2022
Dr Lai is a very good Doc and his office staff is very friendly and helpful !! A+ RATING
April 25, 2022
Very professional personal.
April 22, 2022
The doctor is very smart but I felt as his evaluation was too quick of my overall kidney -bladder health, just based in a ct scan, with no questions of me to determine if there were other issues or not. I went to ct scan due to pain, and xcessive urination, pressure in my pelvis and lower back - didn't get to say that. Plus I'm not sure if he actually saw the scan and based his decision on the narrative provided by image company. Thank you
April 21, 2022
Front office staff needs to be attentive, pleasant and courteous. I requested something regarding my medical files and they did not assist me with info. I felt like they didn't really pay attention as to what I was asking for. I'm not happy about that. Seems like they didn't put much effort to assist me on that. I would greatly appreciate it if someone from PIH can get in touch with me regarding this matter. Thank you.
April 19, 2022
The doc was very thorough and informative
April 18, 2022
Office staff takes too long to answer phone calls. When you're there for your appointment it's a little bit too long to see the doctor.
April 15, 2022
Dr. Lai and staff are VERY pleasant to deal with.
April 14, 2022
I told the Dr that I was so Glad he's now part of the PIH Group and glad that I could now see him on the Portal. I also told the staff I was very happy with the Dr and Staff. The Doctor was happy that I was glad he's now part of PIH. This Doctor is very professional and caring.

Everyone at the office is very caring and compassionate.
March 29, 2022
Dr. Lai was knowledgeable and very even tempered, very pleasant to deal with, and seemed to have a very logical and reasonable approach for my particular case and situation. His office staff were patient and helpful and I would definitely recommended this doctor.
March 29, 2022
Got new information from Dr. Lai that I was not familiar with. Dr. Lai was very helpful and sympathetic in re to my problem..
March 25, 2022
Dr. Jason Lai provided the background to the steps he will use in my treatment. He also explained clearly the next processes he recommended for me.
March 22, 2022
Dr. Lai was very patient and explained to me the different options and possibilities. My concern is that I didn't realize I will be working with a licensed nurse for the procedure. So I was taking a bit of by surprise on that. That was my biggest concern versus a doctor.
March 21, 2022
Dr Jason Lai and staff was very professional
March 21, 2022
understanding to my needs.
March 18, 2022
Dr was Matter of fact, not a good lister, talk fast and didn't seem to care. Your visit 200.00. He spend less than 5 mins with me. I left feeling mad and bother.it sucked I will never recommend that office. Maybe he doesn't like his job,
March 15, 2022
We are so glad to be back with Dr. Lai when last year, when the company changed. We were told, we couldn't see him anymore. And when we went to a different urologist, which put my husband on medication, that he should never been put on. So we're definitely glad to be back with Dr. Lai.
March 15, 2022
Dr.Lai is a exceptional person and well caring for me as a patient. Thank you.

March 04, 2022
Good evening. This is (PHI removed). I am very glad to receive care from Dr. Lai. I am totally confident on his expertise, which is kidney disease, radiologist and I liked him very much, all the medications that he has given me being. Alright, I really correct. The problems that I have and I totally would recommend him as a physician. I like totally a lot.
March 04, 2022
I had to wait 8 wks for an appointment. Unacceptable!!! MD didn't really explain anything about my condition or the medication he prescribed. He wasn't very clear about anything. The front office wasn't very helpful or efficient. I'm loath to return for a follow up.
March 03, 2022
Good communication with me
March 03, 2022
Very crowded reception area and the staff were not very friendly
February 25, 2022
Dr Jason is very profecional thanks...
February 24, 2022
(INAUDIBLE) I never see just few minutes. It's terrible need some time to speak with the doctor (INAUDIBLE) the personal. It's so so food is terrible bad. It's terrible. I no recommend this hospital to somebody else. Okay. Thank you.
February 24, 2022
The doctor was very good. She give us our time to explain. The problem is with the office. The office leaves you on hold for a very long period of time. Sometimes they pick up and hang up when you had already been on hold for 15 to 20 minutes. They need to pay a little bit more attention to to have a better phone system office. That's it. Thank you.
February 24, 2022
All staff were pleasant and courtios, i was treated with respect , wish all dr offices showed the same to there patients.
February 24, 2022
The physical reception area and furnishings are worn, old, and unattractive. The office atmosphere is cold and uninviting. No complaints about the personnel; or the attention. The care was certainly, excellent and the physician and staff are very caring
February 24, 2022
One of the best experiences with a Dr that I've had in a long time.
February 22, 2022
February 22, 2022
I have absolute support for Dr. Lai he is a great doctor. Gives me the information I need and I trust him. Absolutely. Thank you.
February 22, 2022
When I took my father to the doctor's office, I specifically asked the nurse to let me know what was going on. And that I could speak with the doctor. Since my father, forgot a lot of the things that the doctor would say. And I couldn't go in the office with the doctor because my father did not want me to. Although he doesn't mind me knowing things, but it was a very personal... personal part of his body that had to be revealed. And of course, I wasn't going to go in there, but the doctor never ones came to speak to me. And I had asked that I know what's going on. So that's the reason why I am making a comment. I'm done.
February 22, 2022
He is a professional doctor with a kind and approachable attitude! Thank you Doctor !
February 17, 2022
I enjoyed the, the receptionist and the assistants help, very well.
February 17, 2022
They are very busy and could probably use some extra help and some new computers!
February 07, 2022
February 03, 2022
We are very pleased with this office. They always see us quickly, they're always courteous, polite and professional.
February 03, 2022
Very friendly, helpful and professional
February 01, 2022
Excellent service. Thank you.
January 28, 2022
It is absolutely impossible to speak to anyone in the office on the phone. You are held on, on hold for 10 minutes at a time and it's it's impossible to get through and when I'm told that I will get the results and they'll call me. I'm still waiting and waiting and waiting.
January 28, 2022
Dr. Lai is a remarkable doctor, he's very compassionate, he listens to you and he's been wonderful as my doctor thank you.
January 27, 2022
Shprt and easy to understand.
January 26, 2022
The office staff could try to meet the patient's needs by trying to be more flexible in scheduling appointments. It seems as if they are not willing or able to make a special effort if a patient has an urgent need in regard to time.
January 26, 2022
I have the utmost respect for [name removed] and staff and would highly recommend his services to family and friends. They are knowledgeable, patient-friendly, and exude a level of expertise that is admirable.
January 24, 2022
They treat me very well, and I'm very happy and I say thank you. I would recommend everybody over there. Thank you. Bye.
