About Me

I am a board-certified radiation oncologist specializing in the treatment of breast, gastrointestinal and lung cancer. I’m dedicated to helping people understand their treatment options and feel supported after a cancer diagnosis. Working as a team with other Penn State Health providers, I make sure every patient receives the most advanced care possible. I’m Gamma Knife certified and skilled in stereotactic body radiation therapy, which uses very focused beams of radiation to target tumors.

My research is focused on improving radiation therapy quality and advancing cancer care for patients with gastrointestinal malignancies, and I am nationally recognized for my work in these areas.

I started my career at Penn State Health, then briefly relocated to New York to work at Northwell Health, where I was recognized on the New York Times Super Doctors list from 2024 to 2026. I am now proud to return central Pennsylvania and provide exceptional cancer care to our local community.
