From the Doctor

I am a North Florida native and lifelong University of Florida Gator fan who grew up in Union County, where I was the valedictorian of my high school class.

I believe caring for cancer patients is a great honor in life, and I feel we should always be pushing the envelope to improve cancer treatment.

A few years ago, I participated in a radiation oncology mission trip to Nicaragua and served on the board of a Samaritan Free Clinic.
