Medical Director

Dr. Margaret Sande

Margaret Sande, MD, MS, MSHPED

Medical Director | (720-848-5437) 

Dr. Sande is Medical Director of the WELLS Center. She is an Assistant Professor of Emergency Medicine at the University of Colorado School of Medicine and serves as Director of Simulation for the Denver Health Emergency Medicine Residency Program.

With a background in biomedical engineering. Dr. Sande’s interests lie at the intersection of technology and medicine. Dr. Sande began her academic career focusing on medical device design, and she is a patented inventor as a result of her work. It was during her training as a an emergency physician and chief resident that she developed an interest in human factors research and approaches to demonstrate proof-of-concept for emerging technologies. She subsequently completed a fellowship in medical simulation, where technology is utilized as an educational tool applied to medicine. She completed her second master’s degree in health professions education focusing on medical education pedagogies and associated research methods.

Dr. Sande continues to be involved in simulation-based education research and the use of simulation as a means of proof-of-concept for novel technologies. Dr. Sande employs high-fidelity mannequin simulation to train students, physicians, nurses, advanced practice providers, and interdisciplinary teams. She has shared her expertise as a consultant with health organizations internationally.
