Brief Biography

Dr. Benson graduated from the Chicago Medical School in 1974. His first two years of paediatric training took place at The Hospital for Sick Children in Toronto and in 1976 was senior resident at St. Christopher’s Hospital for Children in Philadelphia. Subsequently, he returned to Toronto for Cardiology fellowship at The Hospital for Sick Children and in 1979 entered graduate school at UCLA Medical School in Biophysics and was a research fellow for Dr. Bill Friedman. In 1980 he joined the clinical staff at UCLA Medical School, and was the Co-Director of the Intensive Care Unit. In 1983 he rejoined the clinical staff at The Hospital for Sick Children in Toronto as the Director of the Cardiac Catheterization Laboratories. Dr. Benson developed the interventional program in cardiac catheterization at The Hospital for Sick Children, which today is one of the largest programs in North America. He is author of over 250 original articles, numerous book chapters, and several textbooks. In addition to his focus in Interventional Cardiology, a major interest and clinical focus is in the management of heart failure and cardiomyopathies in paediatrics.
