He went on to receive his Doctorate in Medicine from New York Medical College in Valhalla and was elected to Alpha Omega Alpha in 1984. Dr. Procaccino relocated to Long Island in 1984 when he began his Internship in General Surgery at North Shore University Hospital. He completed his five-year training in General Surgery at North Shore after finishing his Chief Resident year in June 1989.

A leader in the treatment of colon and rectal disease, Dr. John Procaccino provides superior healthcare services to his patients. He has been the Director of North Shore University Hospital’s Center for Colon and Rectal Diseases since its inception 14 years ago. Dr. Procaccino brings his distinguished 30-year track record of success in the field to this Center in order to fill any significant void in the healthcare resources available on Long Island.

Dr. Procaccino has deep roots in the Long Island community and invested much of his specialized knowledge in elevating the standard of colon and rectal disease treatment in the area. Since 1990, he has been a staff surgeon at Long Island Jewish/Hillside Medical Center, St. Francis Hospital, and North Shore University Hospital in Manhasset. In 1998, he was asked to assume the role of Chief of Colon and Rectal Surgery at North Shore University Hospital in Manhasset. This was a particularly meaningful appointment for Dr. Procaccino as he completed his entire residency at North Shore University Hospital and was thrilled to return “home” to such a prominent position. In March 2001, Dr. Procaccino left private practice to assume his current position as a full time faculty member on the staff at North Shore University Hospital and Long Island Jewish Hospital. In this capacity, he was charged with the task of forming a Division of Colon and Rectal Surgery for the North Shore University Hospital and Long Island Jewish Hospital Department of Surgery, and soon took on the coveted position of Chief of this Division. Dr. Procaccino’s administrative responsibilities at North Shore University Hospital have recently expanded as he has been named a Vice Chairman of the Department of Surgery.

Dr. Procaccino was initially doubly boarded in General in 1990 and in Colorectal Surgery in 1992. He was recertified in General Surgery in 1999 and again in 2009; recertified in Colon and Rectal Surgery in 2000 and again in 2011. He became a fully certified surgeon immediately following his tenure as a Special Fellow and Administrative Chief Resident in the Department of Colorectal Surgery at the prestigious Cleveland Clinic Foundation in Ohio. There, Dr. Procaccino trained under Dr. Victor Fazio, who was widely regarded as one of the world’s top practitioners in the field of colorectal surgery. A sought-after expert in his medical specialty, Dr. Procaccino has been called upon by a host of academic institutions to provide instruction and lectures. He is currently an Assistant Professor at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell. Moreover, he is widely published in a variety of medical journals, and has presented findings to numerous preeminent associations, including the American Association for Cancer Research, the American Society of Colon and Rectal Surgeons, and the American College of Surgeons. In fact, Dr. Procaccino had the distinct honor of being asked to write the chapter about ulcerative colitis in the 5th and 9th editions of Current Surgical Therapy, which is commonly referred to as the “bible” for doctors-to-be who are preparing for their board certification examinations.

Dr. Procaccino lives on Long Island with his wife and three children. He is affiliated with more than a dozen renowned professional societies and has received numerous awards and honor society appointments in recognition of his success, including being elected by his peers for inclusion in Best Doctors in America from 1996 to 2017, and named to NY Metro Top Doctors by Castle Connolly Medical, Ltd. In addition, Dr. Procaccino was named to Strathmore’s Who’s Who in 2000 to 2017. From 2011 to 2017 Dr. Procaccino was named to Castle Connelly’s list of Best Doctors in New York which is published annually in New York Magazine. Inclusion is limited to individuals who have demonstrated leadership and achievement in their occupation, industry, or profession.

Perhaps Dr. Procaccino’s most significant contribution to the field of Colon and Rectal Surgery is his training of the next generation of surgeons. Since 2003 Dr. Procaccino has been the Director of the North Shore/LIJ Fellowship Program in Colon and Rectal Surgery which is accredited by the American Board of Colon and Rectal Surgery. Dr. Procaccino and his associates have recently matched their fifteenth Fellow candidate.

These individuals are now providing the most innovative and cutting-edge therapies for their patients with colon and rectal disorders.
