School of Medicine



During my medical school training at the University of Massachusetts Medical School, I was fortunate enough to rotate through the anesthesia department and surgical ICU as a third year student. During these rotations I met many individuals who were enthusiastic about their roles as anesthesiologists and intensivists. It only seemed natural to me to pursue an anesthesia residency en route to a critical care fellowship. How else could a physician care for a patient so intricately, both intra-operatively and post-operatively?

I spent my internship year at Carney Hospital in Dorchester, MA before returning back to UMass Medical School to complete my anesthesia residency. I was fortunate enough to be chosen as one of the chief residents during my last year of training. The training I received truly prepared me to be able to handle any medical situation. Upon graduation I spent the next year at Brigham and Women’s Hospital in Boston, MA pursuing a critical care fellowship. I returned to UMass Medical School and UMass Memorial Medical Center to begin my career as an attending because of my interest in academic medicine and also because of the wonderful support I received as a resident.


Soon after starting my role as an academic anesthesiologist and intensivist, I was given the opportunity and challenge to help reshape the institution’s pre-surgical evaluation department. Shortly before returning to UMass Memorial, three different pre-testing centers were combined into one. A few months into my efforts I was named the medical director of the Pre-Surgical Evaluation Clinic. It has become an exciting time in re-shaping institutional and departmental policies. My current schedule has me rotating through the operating room where I enjoy giving anesthesia for vascular and thoracic cases; spending time in the surgical ICU’s; serving as medical director of the pre-surgical testing center; and being involved with resident and medical student education through clinical teaching and lectures.
