Summary

I am a Board-Certified Radiation Oncologist with a specialization in tumors of the Head & Neck,
and Base-of-Skull. Following post-residency training in Head & Neck cancers, I have more than
35 years of clinical experience in this field. My training and expertise includes the application/administration of Rapid-Arc IMRT-VMAT, robotic Cyberknife Stereotactic Radiosurgery,
and Proton Beam therapy, as well as implant brachytherapy radiation and use of electron beam treatment. I hold the position of Professor (Full-Time) at the Georgetown University School of Medicine, Georgetown University Hospital and Vincent T. Lombardi Comprehensive Cancer Center.
