Dr. Chao chose to go into medicine because, “helping someone is one of the best and most rewarding feelings that one may experience. It is even more so when a life may be enriched and made even better. Family Medicine is all encompassing care from birth to end of life.” He enjoys getting to know his patients and their families and being able to establish great relationships while caring for their healthcare needs.

Dr Chao and his staff were super helpful and friendly. I got an appointment within a half an hour of me needing one. I don't usually like to see doctors when I am sick but I am so glad that I went because he was able to diagnose me and treat me. It has only been 24 hours and I am feeling so much better. I will definitely be making him my PCP
