Best-selling author on medical weight loss. Medical Director of Wellness Haus, Toronto.
Dr. Hershberg has spent her career at the intersection of medicine and weight loss — long before GLP-1 medications became part of mainstream care. Today she leads the Wellness Haus medical weight loss program, where the medication is one tool inside a comprehensive, physician-managed practice.
Dr. Melissa Hershberg is a Toronto-based physician (MD, CCFP) and a recognized authority on medical weight loss. She is the author of best-selling books on weight loss and metabolic health, and she has been featured by The Marilyn Denis Show, CTV, and other major Canadian media outlets.
At Wellness Haus, Dr. Hershberg leads a physician-led GLP-1 program designed around what the medication alone cannot do: comprehensive bloodwork, body composition monitoring, dose titration, plateau management, complication support, and the long-term aesthetic and metabolic care that serious weight loss requires.
She practices the way she writes — with precision, with patient-first judgment, and with the conviction that weight loss is medicine and deserves to be practiced as such.
