Dr. Diamond is based in our Plainview Radiation Facility.

Ezriel Diamond, MD is a Board Certified Radiation Oncologist who has practiced in the Long Island community for nearly 20 years. He is considered a leader in the field of Radiation Oncology in the New York Metropolitan area, recently being named to Newsday’s “Top 10 Physicians List”. Dr. Diamond has been a pioneer in the field of Radiation Oncology on Long Island, where he began his career at North Shore Hospital in Manhasset, helping to grow the facility’s Radiation department which was then in its infancy. Later he founded his private practice in Plainview, NY, a practice that has grown into the largest Radiation Oncology facility in the tri-state area.

Dr. Diamond’s expertise includes the treatment of all malignancies, with radiotherapy, with further specialization in the treatment of breast, lung and prostate cancers, as well as gastrointestinal and gynecologic tumors.

Dr. Diamond actively participates in multidisciplinary tumor board conferences in the Long Island area, including those at North Shore-LIJ hospitals. He was a recent co-honoree (along with fellow ARC colleague, Dr. Shawn Zimberg) at the 4th annual Lean-On-Me Breast Cancer Network Gala.
