An expert in melanoma, surgical oncologist Hans Schoellhammer, M.D., F.A.C.S., says his work gives him special satisfaction. “By working with one’s hands,” he says, “one can treat patients and have an immediate and dramatic impact on their health.”
Dr. Schoellhammer is double board-certified in both surgery and complex surgical oncology. He earned his medical degree from Drexel University College of Medicine in Philadelphia. He completed general surgery training at Harbor-UCLA Medical Center as well as a research fellowship at John Wayne Cancer Institute in Santa Monica, before coming to City of Hope in 2012.
Working out of our Antelope Valley and Mission Hills practices, as well as at the City of Hope main campus in Duarte, California, Dr. Schoellhammer publishes frequently on new treatments for melanoma and other cancers.
