Episcopal Health Services Welcomes Radiation Oncology Chief

Far Rockaway, New York, October 31, 2025 — Episcopal Health Services (EHS) is pleased to announce the appointment of Mark Ashamalla, MD, as Chief of Radiation Oncology. In this role, Dr. Ashamalla will lead the development of a comprehensive radiation oncology program that combines advanced technology, innovative therapies, and research-driven approaches to deliver the highest quality person-centered care.

“Dr. Ashamalla’s expertise in cancer treatment and research will round out EHS’ oncology services and bring radiation therapy back to the peninsula for the first time in more than a decade,” said Donald T. Morrish, MD, MMM, Chief Executive Officer at EHS. “His leadership will be instrumental in further strengthening a robust program that pairs cutting-edge technology with pioneering clinical approaches to achieve optimal patient outcomes.”

“The appointment of Dr. Ashamalla allows us to establish a radiation oncology program that meets the highest standards of care,” said Jameela Yusuff, MD, MPH, MS, FACP, Senior Vice President & Chief Medical Officer. “His experience ensures patients in our communities can access advanced radiotherapy locally, improving convenience, continuity, and quality of care.”

Prior to joining EHS, Dr. Ashamalla served as a clinical assistant professor of radiation oncology at Stony Brook University Hospital. A board-certified radiation oncologist, he brings extensive expertise in cancer care, research, and education, with a focus on personalized, evidence-based treatments, improved patient outcomes, and addressing disparities through clinical and translational research.

Dr. Ashamalla earned his medical degree from Jefferson Medical College, now Sidney Kimmel Medical College at Thomas Jefferson University, and completed his residency and chief residency in radiation oncology at New York-Presbyterian Brooklyn Methodist Hospital. An accomplished clinician and researcher, he has published in peer-reviewed journals, contributed to leading oncology textbooks, and presented nationally on advances in cancer treatment. His contributions have been recognized with multiple awards, including honors from the Radiological Society of North America and the American Society for Radiation Oncology.

Radiation and medical oncology services will be housed in EHS’ forthcoming Walsh Ambulatory Pavilion. The pavilion will feature advanced technologies such as GE PET/CT imaging for accurate diagnosis and monitoring, and TrueBeam™ radiotherapy for targeted, nonsurgical treatment. Primary care, behavioral health, OBGYN, and other medical services will also be offered in the facility, making it easier for patients to access comprehensive care all in one location.
