    The two people that I interacted with were professional funny and they set my mind at ease about the operation they wanted to perform good job
    Nov 24, 2023
    Follow-up treatment instructions were to be provided via a scheduled phone call. Nurse called but she didn't have orders from the doctor and couldn't provide instructions. Still don't have prescription or instructions.
    Nov 23, 2023
    I had read about the procedures prior to our call and Dr. Chi answered all my questions sufficiently.

    Nov 02, 2023
    Nice and knowledgeable of his specialty. Kind and listens well to my complaints; was concerned and facilitated follow-up being a new patient with new dose of my drug .
    Nov 02, 2023
    Dr. Chi was both high professional and personable. Knowing I warranted Pyeloplasty kidney surgery I was understandably concerned. He provided my level of medically knowledgeable explanations not base level generic info. He won my heart when I asked him "Will you take care of me and he responded like family." That was all I needed to hear to have faith and trust in him. I already knew his professional expertise and world renowned qualifications.

    Excellent care
    Oct 22, 2023
    Incredibly personal and capable
    Oct 22, 2023
    UC bureaucracy is byzantine. Recommending UC services would come with clear warnings about the challenges of scheduling.
    Oct 12, 2023
    Thank you very much for making my doctor's visit a positive one. Good job to whoever hired the amazing staff
    Oct 12, 2023
    Dr. Chi is very knowledgable and his experience is appreciated. He informed me of what was happening during the procedure using the TV screen and pointing out the anatomy and areas affected. He efficiently summarized the 3 options for proposed treatments then provided them in writing in MyChart. I feel that I have enough information to make a decision on how to move forward.
    Oct 08, 2023
    Contact with care provider was state of the art

    Was thorough on answers to questions
    Aug 27, 2023
    Very good experience.
    Aug 23, 2023
    I can't recommend this care provider when UCSF staff does not thoroughly follow with resources nor appointments. The Doctor was very Good however as far as anyone calling me back as to where to go for Ultrasounds and appointment follow ups is severely Flawed.
    Aug 17, 2023
    Dr Chi is an outstanding Urologist.

    Visit was a bit short.
    May 17, 2023
    Did not get answers on (1) surgical options and (2) scheduling surgery.
    May 04, 2023
    The whole team was outstanding.
    Apr 22, 2023
    Dr. Chi is great and I appreciated the opportunity to reconnect with him since I began my care with his team about 4-5 years ago.
    Mar 28, 2023
    Everything is good
    Feb 16, 2023
    Dr Chi appears to be an excellent clinician and has wonderful bedside manner. My procedure went very well and follow up has been thorough. Thanks again Dr Chi!
    Feb 05, 2023
    The doctor (Thomas Chi) his assistants nurses and staff were engaged competent aware of the patient's vulnerability and dedicated to their work. But they were in my experience overwhelmed with patients and possibly under staffed.
    Jan 26, 2023
    Dr. Chi reviewed my past test results & images with me; and even pulled them up on the screen so that I could see & understand. He listened & showed empathy to me because as a previous cancer survivor I was distraught about a possible diagnosis of cancer. Dr. Chi took the time to answer all of my questions; recommended additional testing and why it was needed. He was awesome!!!
    Jan 19, 2023
    My experience with UCSF was very positive.
    Jan 03, 2023
    Dr. Chi was superb
    Dec 22, 2022
    Dr. Thomas Chi is the best. He takes extra effort to listen to me and determine what my medical state is. He responds to questions in a straightforward and direct manner. He is very positive and encouraging. Simply awesome!
    Dec 09, 2022
    I did not get a after visit summary. When I asked why not I never got a response. I finally wrote my own after visit summary. Then later I finally got a summary.
    Dec 09, 2022
    My care provider presented as warm easy to talk to and very knowledgeable.
    Dec 04, 2022
    Nov 06, 2022
    The Dr was beyond kind and so thorough. We had a difficult subject to discuss (cancer) but he handled it very well.
    Nov 03, 2022
    Dr. Chi is EXCELLENT!
    Nov 01, 2022
    There was a discussion about my health rather than a one-way conversation. I appreciate that.
    Oct 29, 2022
    It would be hard for me to recommend Dr. Chi just because my recovery from the HOLEP surgery has been the most difficult health struggle of my life. It may well not be his fault but still I'd be uneasy to recommend this surgeon and procedure given the protracted incontinence and pain.
    Oct 27, 2022
    This provider is one of the best ever caring friendly courteous skilled and professional.
    Oct 23, 2022
    Excellent in all respects
    Oct 22, 2022
    My appointment was with Dr Chi but a PA arrived to do the procedure. I told the nurses and was fortunate after a very short wait to then have Dr Chi perform the procedure -

    The worst
    Sep 09, 2022
    Dr. Chi has been a wonderful care provider patient friendly explicit and knowledgeable! It's never been a sacrifice to travel 3 hours for pre-eminent medical services. I truly appreciate the ability to deal with the ordinary through distance communication.
    Sep 01, 2022
    It would be hard for me to recommend Dr. Chi just because I fell into the 3 - 4% of patients who have a very long and difficult recovery from the surgery. I've had the worst health of my life since the surgery so I just can't be too glowing in recommending it to others.
    Aug 25, 2022
    I like Dr. Chi and know he's a good surgeon. However that doesn't help if there is no access or response when I need help with my concerns. So I don't know how to give a recommendation.
    Aug 04, 2022
    I come to UCSF for treatments because of doctors like Dr. Chi.
    Jul 31, 2022
    Dr Chi is friendly professional and a very good listener. Always good to talk with him.

    Dr. Chi is caring professional and trustworthy
    Jun 02, 2022
    It was a first visit only 15minutes. Did not feel there were answers to my questions but rather offered more tests and prescription without discussion. After the appointment I had lots of questions.
    May 29, 2022
    Dr.Chi represents the very best level of knowledge empathy communication and responsiveness all doctor's should strive for
    May 02, 2022
    Very good communication of complex surgical options and outcomes. Very thorough and skilled.

    Provider a bit brusque and in a hurry but adequately attentive.
