Dr. Sandra Tsai is a wonderful doctor in every respect. I am extremely grateful to her for being so thorough -- if it weren't for her requesting a heart scan when she first examined me a year or so ago, - which she explained was not really necessary based on my symptoms, but she highly recommended anyway--I would not have known that I have an enlarged aorta, and that it was extremely important to monitor it and keep my blood pressure low from now on. I am truly indebted to her, and to Stanford for having such high quality and caring doctors.
The two doctors that I dealt with were amazingly good communicators and gave me great confidence that they were extremely knowledgable and that we would figure out what my medical issues were in a reasonable time frame. They were also really nice and genuine people.

visit was exemplary as usual
My doctor went out of her way to check with another specialist on an issue and got back to me immediately.
Dr. Tsai had obviously looked carefully at my previous appointment notes and tests before my visit and was very well informed.
I came prepared. having taken my tests and studied the results in advance; she answered all my questions (kudos to the blood lab for same-day results and an online format that displays all results for the last four years)

Dr. Tsai is one of the most professional, thorough, caring physicians I have ever had the good fortune to find. When I send her an email, she is responding to it late in the night or early in the morning. She listens to my problem(s) and acts to determine what the issue might be. DR. SANDRA TSAI IS ABSOLUTELY WONDERFUL!!!
The doctor's office visit itself went very well. It would've been helpful to know in advance, when scheduling the "new patient" appointment, what to expect in terms of an exam. I had anticipated a full physical exam, especially since it has been over a year since my last one at PAMF. However, I learned from the nurse when I arrived that the "new patient" exam would not be a comprehensive physical exam and it wasn't. Nevertheless, I am generally healthy, and the few problems I had at the time were addressed by the doctor and followed up with a referral (based on the xray results).
She's wonderful!
dr. Sandra say is a wonderful caring doctor she calmly explained medications to me she is doing a follow up with me on test results that I'm getting from another doctor that she would like to review she is awesome she let me cry and she was very understanding and didn't make me feel rushed and as if she didn't care she does care I highly recommend her and I look forward to my next visit with her
