About me
Dr. Lischalk is a board-certified radiation oncologist with extensive experience in stereotactic radiosurgery, stereotactic body radiation therapy, intensity modulated radiation therapy, and proton beam therapy. In addition to his positions as clinical director of the radiosurgery service and specialty service director of the Genitourinary Cancer Program at MedStar Georgetown, he serves as assistant director of the clinical trials office at Georgetown Lombardi Comprehensive Cancer Center, vice-chief of clinical research for Medstar Radiation Oncology, and is a clinical associate professor at the Georgetown University School of Medicine.
Before joining MedStar Georgetown, Dr. Lischalk held several leadership positions at New York University Perlmutter Cancer Center, where he served as medical director of the NYU CyberKnife Center, director of research for the NYU-LI Department of Radiation Oncology, and clinical associate professor in the NYU-LI Grossman School of Medicine.
