Service to Other Organizations

  • Member, Advisory Committee on the Medical Use of Isotopes (ACMUI), Nuclear Regulatory Commission (NRC), March 2015-Present.

Dr. Ennis currently serves as Chair of the ASTRO Government Relations Committee, a committee on which he has served since 2006. Last year, he was appointed to the Advisory Committee on the Medical Use of Isotopes for the U.S. Nuclear Regulatory Committee. This twelve-member committee, only two of whom are radiation oncologists, advises the NRC on regulatory issues related to the medical use of radioactive materials including brachytherapy and Gamma Knife radiosurgery. In these roles he has gained a wealth of knowledge and experience in health policy as it relates to radiation oncology and in governmental advocacy as it relates to the needs of radiation oncology and its patients.

He is also the Director of Radiation Oncology at Mount Sinai West Hospital and Associate Professor of Radiation Oncology at the Icahn School of Medicine at Mount Sinai in New York City. Additionally, he serves on several key cancer committees within the newly formed Mount Sinai Health System (MSHS), including the MSHS Cancer Steering Committee, the MSHS Cancer Quality Leadership Council and the MSHS Oncology Care Model Implementation Committee.

He has experienced first-hand the dramatic changes to health care having been on the staff and faculty of Columbia Presbyterian when it merged with Cornell-New York Hospital and Roosevelt Hospital/Continuum Health Partners when it merged with Mount Sinai. These experiences have provided further education regarding health care policy and its effects on physicians and patients.

In addition to these administrative roles, Dr. Ennis has published extensively, mainly in prostate cancer, and has served on the GU ASTRO Annul Meeting Scientific Program Committee and chaired that committee for two years. He maintains vibrant clinical practice and clinical research programs.
