Dr. Sherin Ibrahim Howett's Professional Path

I started my journey into medicine after high school by attending a 7-year accelerated program and graduating from the New York College of Osteopathic Medicine (NYCOM) in 2003. As an Osteopath, I believe in the philosophy that focuses on the body as a whole, instead of individual unrelated parts. Taking the road less traveled, I decided to complete an Osteopathic Rotating Internship at St. Vincent’s Midtown Hospital in Manhattan. In a hospital without residents, I learned to be efficient with my time, delegate authority and deal with the stress of being solely responsible for another's life. From there, I went on to do an Internal Medicine Residency at Morristown Memorial Hospital in NJ. My time in residency gave me the opportunity to learn evidence based medical practice, look at long-term goals of my patients and expand my fund of knowledge. I was also fortunate enough to have worked with Dr. Marc Benton, who introduced me to the field of Sleep Medicine. With his encouragement, I applied and successfully completed my Sleep Medicine Fellowship training at Clinilabs, Inc. in Manhattan in 2008. I just completed a 2-year surgical Critical Care Fellowship at Mount Sinai Hospital in Manhattan this past June 2010. The ICU allowed me to be meticulous about details, manage chaos and address end of life issues with patients and families.
