15 year reflections


In our first 15 years we have made medical history as the first to offer proton therapy in the state of Florida and all of the Southeastern United States. We have treated more than 10,000 patients. We have opened over 65 clinical trials and published more than 300 studies in peer-reviewed scientific medical journals. We are dedicated to the pursuit of excellence in patient care, education and research.

Hear from some of our staff members, many with us since day one, as they reflect on what the 15-year milestone means to them. After all, it is our people who have made it all possible.
