When my husband wasn't feeling well, and we thought something was wrong with him, Dr. Tsai got us into his office immediately. He ordered labs, reports, and everything that we needed to make certain that my husband was ok. He sat with us and explained EVERYTHING and he explained it in terms that we could understand. He is a wonderful doctor and his office staff is also very nice to deal with.

Dr. Tsai's Care Philosophy

I try to communicate with my patients. I strive to explain their medical condition and discuss their treatment options in plain language. Questions are answered. I want no patient to leave the office thinking they were rushed through their visit
