Our Team

Dr. Andrew Tran


“Every patient should be treated as if they were a member of our family,” a sacred principle that Dr. Sam Williams has entrusted in me and as such, I will continue to provide the friendly, quality and respectful care you have come to expect from this office over the years.

A Florida native, I grew up in Tampa where much of my family still resides. My wife and I have two young children and a sweet labradoodle named Charlie. I currently reside just outside the north Orlando area. Aside from work and family, I enjoy archery, playing guitar, working out, and sipping fine whiskey. I am a proud fan and supporter of the U of F Gators. Go Gators!!
