Deborah S. Keller, MD, MS has joined the Division of Colorectal Surgery at NewYork-Presbyterian/Columbia University Medical Center as of April 1, 2018 as Assistant Professor of Surgery at CUMC.

Dr. Keller joins us most recently from New Brunswick, NJ. Dr. Keller has a Masters Degree in healthcare policy and management from Carnegie Mellon University, worked as a healthcare business analyst for several years and then completed her MD at Rutgers University. She did her surgical residency at Temple University Hospital, Philadelphia followed by a Colorectal research fellowship at University Hospitals-Case Medical Center, Cleveland and a Colorectal clinical fellowship at St. Vincent Medical Center, Erie, under Dr. Daniel Geisler, and Baylor University Medical Center, Dallas, under Dr. James Fleshman.

Dr. Keller’s clinical expertise includes laparoscopic, robotic and minimally invasive colorectal surgery, anorectal procedures and the management of pelvic floor disorders. Dr. Keller is an outstanding researcher with numerous peer-reviewed journal articles, presentations, book chapters, and books to her name. She has an interest in surgical quality with a focus on perioperative management including enhanced recovery after surgery (ERAS) pathways, multimodal opioid-sparing pain relief, and expanding use of minimally invasive technique to optimize patient outcomes. She also has an interest in rectal cancer management and is currently completing her PhD on the topic at the University College of London, UK where she holds an appointment as an honorary lecturer in gastrointestinal surgery.

Dr. Keller sees patients at her main office at NewYork-Presbyterian/Columbia, 161 Fort Washington Avenue, 8th floor, in Manhattan. She is also seeing patients at 25 Rockwood Place, 3rd floor, room 330 in Englewood, New Jersey and will partner with Dr. Geisler to expand the Division’s colorectal expertise in New Jersey and other locations, while furthering the academic and research missions of the division.
