About me

Dr. Grosse-Wortmann received his medical degree from the University of Würzburg in Germany. Following training in pediatric cardiology in Aachen (Germany), he moved to Toronto to complete his cardiology training as well as a two-year fellowship in advanced cardiovascular imaging at The Hospital for Sick Children. He accepted a faculty position there in 2008 and directed the cardiovascular MRI section as well as the connective tissue disorders clinic. He joined Doernbecher Children’s Hospital in 2019 as the division head of pediatric cardiology.

Dr. Grosse-Wortmann is passionate about caring for children with heart disease. He specializes in echocardiography, MRI and CT imaging. His research focuses on the health of the heart muscle as well as on the physiology and long-term outcomes in children with congenital heart disease. Outside of work, he shares his love for the outdoors with his wife and twin boys.
