Dr. Zhao

Meet Sherry Zhao, D.M.D

Dentistry is a wonderful combination of art, science, and healthcare. My mission as a dentist is to provide the best care to my patients and to be a part of and foster a healthy, productive work environment. In my free time I enjoy hiking, running, reading, and spending time with friends and family.
