Collin Brathwaite, MD, FACS, Chairman of the Department of Surgery at Winthrop-University Hospital, is pleased to announce that John D. Allendorf, MD, FACS, has been named head of Winthrop’s Pancreatic Cancer Program. A renowned surgeon, Dr. Allendorf has pioneered several robotic and minimally invasive treatments for patients with pancreatic cancer who were previously thought to be untreatable.

With additional specialties including hepato-biliary and endocrine surgery, which involves treatment of the liver and thyroid, Dr. Allendorf will also serve as Vice Chairman of the Department of Surgery and Chief of the Division of Surgical Oncology & Endocrine Surgery.

Dr. Allendorf joins Winthrop from Columbia Presbyterian Hospital, where he was Director of the Pancreatic Cyst Surveillance Program as well as Program Director of the Endocrine Surgery Fellowship Training Program. In these roles, Dr. Allendorf was a major force in the growth and development of the hepato-biliary and endocrine surgery programs at Columbia, as well as the development of Columbia’s program in robotic pancreatic surgery.

“Dr. Allendorf’s arrival at Winthrop represents a major inflection point in the treatment of cancer patients,” said Dr. Brathwaite. “As one of the foremost surgeons in pancreatic cancer in the region, Dr. Allendorf brings to our cancer services program a level of expertise and sophistication that will expand the range of treatment options that we can offer patients right here on Long Island.”

As an innovator, Dr. Allendorf holds a patent in endoscopic gastric bypass. With a special clinical interest in pancreatic cancer and endocrine surgery, Dr. Allendorf has been awarded numerous grants to support his research. His current area of research involves the affect of RAGE signaling on the development and progression of pancreatic cancer.

After completing medical school at Columbia University, Dr. Allendorf continued his training in general surgery with an internship and residency, as well as a fellowship in liver transplantation and hepato-biliary surgery.

Dr. Allendorf’s clinical expertise, commitment to fostering the active learning of residents, and compassion for his patients have been recognized with numerous accolades. These include the Alan O. Whipple Memorial Award for Excellence in Surgery, the Kenneth A. Ford Faculty Research Award, the Teacher of the Year Award by the surgical House Staff of Columbia in 2010, as well as the Patients’ Choice Award in 2010.

The author of numerous book chapters and over 70 original peer-reviewed articles, Dr. Allendorf is a sought-after lecturer at national conferences. He is a member of the American Hepato-Pancreato Biliary Association, the Society of Surgical Oncology, and the American Association of Endocrine Surgeons. He resides in Sleepy Hollow, NY, with his wife and three children.
