About Dr. Wesson

Driven by Patient Progress

My interest in medicine began in childhood, while watching my father’s career as a surgeon. When it came time for me to choose my own specialty, Radiation Oncology offered me the perfect combination of continuously, developing technology with unparalleled patient interaction. I gained extensive experience with advanced, radiation technology, as well as brachytherapy techniques during my training at Memorial Sloan Kettering Cancer Center.

In my 25+ years as a Radiation Oncologist at The Valley Hospital, I have guided thousands of our patients through their successful cancer treatment. I am energized by the opportunity to develop close relationships with each and every person I treat both during their time with us as well as their ongoing follow-up visits. The recent advancements in technology are amazing and allow for fewer treatment sessions with even fewer side effects. I look forward to continuing to provide first-class personalized care to all of our patients.
