Dr Gladstone graduated from the University of Toronto Medical school and then completed residency training in Internal medicine and Cardiology in Toronto. Two years of speciality training in interventional cardiology followed at Toronto Western Hospital after which he then joined the full time staff as director of the Cardiac Cath lab. After the merger with Toronto General (to form The University Health Network – UHN) he relocated to the University Avenue site and also directed the Cardiology residency training program. Later, he moved to Scarborough Centenary hospital to start Ontario’s first “stand-alone” community angioplasty program, which became one of Ontario’s busiest Centres for the treatment of acute myocardial infarction. During this time, he completed his Masters in Public Health at Harvard University. He moved to Victoria in 2016. His research interests have focused on the treatment and prevention of atherosclerotic coronary disease.
