With more than 30 years of experience in leadership roles (previously at St. Luke's-Roosevelt in New York City and New York Medical College in Westchester, NY,) Dr. Brensilver offers an approach to medical education that blends personal mentoring with a focus on pathophysiologic reasoning and an emphasis on interpersonal communication skill development and training in reflectiveness.
