Treatment Philosophy

I chose to work at Fox Chase Cancer so that I could continue my career in oncology at an academic cancer center dedicated to providing quality care.

After graduating from Duke University's physician assistant program in 2004, I began my career in oncology as a physician assistant at the M.D. Anderson Cancer Center in Texas. I worked in the department of gastrointestinal medical oncology for four years, where I specialized in the treatment of gastroesophageal and hepatobiliary cancers. There, I had several manuscripts published in peer reviewed journals, and I presented original research at national oncology conferences.

At Fox Chase, I am focusing on the clinical care of patients with sarcomas and gastrointestinal cancers.
