Dr. Bloch is a native New Yorker and received his B.A. degree in chemistry at Yeshiva University and his Doctor of Medicine degree from the Albert Einstein College of Medicine. He then served a one-year medical/surgical internship at Montefiore Hospital and Medical Center in New York City and a three-year residency in ophthalmology at the same institution. In the final (chief resident) year he was appointed to the teaching faculty of his alma mater, the Einstein Medical College.
Following residency training, Dr. Bloch served for two years as an ophthalmologist and general medical officer in the United States Army during the Vietnam era. He was board-certified in ophthalmology in 1973, moved to Stamford, Connecticut, and joined a private practice in Mount Kisco, New York.
During the subsequent 40-year period Dr. Bloch practiced medical and surgical ophthalmology in both Westchester County and New York City. He also taught courses to students and residents in various hospitals on head and neck anatomy for ophthalmologists as well as the ocular manifestations of systemic disease. Dr. Bloch has published papers in the Archives of Ophthalmology and the British Journal of Ophthalmology, as well as chapters in the texts Clinical Ophthalmology, Compendium of Ophthalmology, Ophthalmic Technology, and Current Ocular Therapy. He has served as chief of ophthalmology at Martin Army Hospital in Fort Benning, Georgia, and Northern Westchester Hospital Center in Mount Kisco, New York. His society memberships include the American College of Surgeons and the American Academy of Ophthalmology.
In 2006, Dr. Bloch retired from private practice but continued to treat patients on a part-time basis as attending physician at Montefiore Hospital. He pursued a new interest in the history of medicine and in 2012 published Healers and Achievers (Xlibris), an 800-page collection of biographies of unique physicians from ancient Egypt to the present time. That same year he relocated to South Florida and has since lectured extensively on the history of medicine. He joined the NSU MD faculty of NSU and hopes to teach medical students about the impact of the medicine of the past on current medical theory and practice.
