Routinely honored as one of the top Doctors in New York by Castle Connelly, Dr. Mark Reiner is a leading general surgeon highly regarded for his contributions to academics as well as clinical medicine. He has held the position of Clinical Professor of Surgery at the prestigious Mount Sinai School of Medicine in New York for more than 25 years. He is also a founding partner of the Laparoscopic Surgical Center of New York. Dr. Reiner is a widely published author and lecturer, and one of the world’s leading specialists on laparoscopic procedures (an advanced surgical technique in which operations in the abdomen are performed through very small incisions as compared to larger incisions needed in traditional surgical procedures.) As the author of scientific articles, book chapters, and textbooks on laparoscopic surgery (including hernia repair, gastrointestinal and tumor surgery), Dr. Reiner has lectured at national, as well as international conferences most recently attending the Joint European and American Hernia Society Meeting in Berlin in September 2009. Dr. Reiner has served in numerous leadership positions at Mount Sinai, one of the leading hospitals in the United States located in the Upper East Side of New York currently serving on its medical board. Dr. Reiner also has served as the Chief of Laparoscopy of the Bronx VA hospital for more than 25 years. Board certified, he is a Fellow of the American College of Surgeons where he just completed a three year term as Councilor and serves as a member of the Board of Governors and as Vice Chairman of the Manhattan Council of the American College of Surgeons. Dr. Reiner performs hundreds of general surgical procedures each year and has trained dozens of residents and fellows in advanced laparoscopic procedures. He specializes in the diagnosis and treatment of hernias (often operating laparoscopically for faster recovery and better outcomes). Dr. Reiner also has substantial experience in the diagnosis and surgical treatment of gastric cancers, colon surgery and breast surgery as well as more routine general surgical procedures.
