Jeffrey Weiss, MD is a senior clinician-executive who has taken on progressive leadership positions at Montefiore Health System. Dr. Weiss earned a bachelor of science in industrial and labor relations from Cornell University, a medical degree from Stony Brook School of Medicine, and the Internal Medicine Residency Program at Montefiore, where he was chief resident.

In 2007, Dr. Weiss was named Institutional Medical Director for Montefiore Health System. His role is to help optimize the performance of the Montefiore health delivery network by ensuring a smooth interface between its various components - the doctors, hospital, medical group, home health agency, nursing homes, and the CMO. Dr. Weiss's responsibilities included leadership of nationally recognized patient safety, quality and peer review programs, management of a medical staff with 3,500 employed and voluntary physicians, supervision of GME activities for 1,200 residents in the second largest house staff program in the country, all under the coordinated umbrella of the "Office of the Medical Director" (OMD). As part of a restructuring of organizational clinical leadership in 2012, Dr. Weiss was named Vice President for Medical Affairs. In this role, he has retained many of his previous responsibilities, and is now leading a team of five newly appointed hospital medical directors in driving physician alignment and creating a horizontally integrated approach to quality and clinical performance across the system.

Dr. Weiss is an active clinician, teacher and researcher. He lectures nationally on topics including leadership, physician alignment, just culture, and patient safety in several forums, including as a faculty member for the AAMC and National Patient Safety Foundation. The Just Culture tool he helped develop at Montefiore is now in use by dozens of hospitals nationally and internationally, and is recommended for adverse event handling by the Joint Commission.
