Dr. Nav Persaud is a Staff Physician in the Department of Family and Community Medicine at St. Michael’s Hospital. He is also an Assistant Professor in the Department of Family and Community Medicine at the University of Toronto.

Dr. Persaud’s research focuses on enhancing the ability of primary care to address health inequities through the development and application of high quality evidence. He is currently leading practice-based randomized controlled trials to: (1) explore the impacts of offering primary care patients free and convenient access to essential medications (details here) and (2) evaluate the potential of xylitol to prevent ear infections and dental cavities in preschool-aged children. Dr. Persaud’s trials are developed with ongoing input from community members and patients.
