    I considered Dr. Tsai a world class doctor. Her Level of knowledge, compassion, respect is beyond that of most providers. I have the utmost level of appreciation for her and her care of me.

    Dr. Tsai was excellent as always.
    Aug 15, 2024
    Dr. Tsai is an excellent physician and listener. I can not see any aspect of her practice, professionalism, or performance that could be improved. She is also brilliant, understanding quickly the details and complications, and then communicating the larger picture with its implications to the patient.
    Aug 04, 2024
    Dr. Tsai was excellent, taking plenty of time to discuss my situation, answering questions, and clearly explaining further treatment options and next steps. I appreciated the clarity of our discussion and the fact that she didn't offer her recommendations for further treatment until she had a pretty good idea of our reaction to the information we discussed. Consequently we didn't feel pressured to agree with her recommendation but felt that we arrived at it together with her. She is excellent!

    I had taken a break from my Keytruda immunotherapy after a severe side effect that landed me in the hospital for 9 days. Between the CITE program and Dr Tsai I felt confident enough to resume the infusions.
    Apr 09, 2024
    Dr.Tsai has a very welcoming, disarming manner. She is so professionally skilled as well as compassionate, patient, and has a kind way of making sure I hear and understand her. I've seen her over several years and am so thankful that she is the oncologist I was referred to during the initial cancer crisis.

    I have been a patient of Dr. Tsai for over six years. I have complete confidence in her ability to make decisions and recommendations that affect my on-going well being.
    Nov 10, 2023
    I really like my doctor. She cares about me.
    Oct 22, 2023
    The only side effect of my immunotherapy that I have noticed has been irritation of my eyes. Dr. Tsai listened carefully to my description of the treatment I have received for this condition from my ophthalmologist, and then offered to make a referral to a UCSF ophthalmologist who has been studying how immunotherapy may cause side effects in the eyes, which I welcomed.
    Oct 20, 2023
    EVERYONE there, went above and beyond what I'd expect from professionals. I couldn't expect anymore.

    Dr. Tsai is wonderful!
    Sep 08, 2023
    Dr. Tsai answered my questions about medications. We were waiting for bloodwork results which showed that I was in need of a transfusion but could possibly have the scheduled infusion as well. We planned for a scan before the next scheduled infusion to see what effect the new immunotherapy has had. Dr. Tsai arranged for the transfusion and I received 2 units of blood and the Opdualog infusion. Excellent coordination and treatment throughout.
    Aug 20, 2023
    Dr. Tsai listened to me and my concerns to help me make the best decisions for my care and treatment.
    Aug 19, 2023
    She was very professional. Apologized for not being my Dr. And I promptly told her not to apologize that Dr.s have things they need to do. I enjoy someone new learning my case
