About the Physician
My Story
For me, medicine has never just been a career—it's been a lifelong commitment to helping people heal, recover, and thrive. What inspires me most is seeing my patients regain their health and confidence, and witnessing how those moments of recovery ripple outward to touch families, friends, and entire communities.
From the very beginning of my medical journey in Family Medicine, I have been driven by a desire to make healthcare more accessible, especially for individuals struggling with mental health and addiction. I've dedicated much of my career to building clinics and programs that reach underserved populations, ensuring that every patient—no matter their background—has the opportunity to receive compassionate, evidence-based care.

Throughout my career, I've focused on three main areas: Addiction Medicine, Sleep Medicine, and Primary Care. I have authored more than 48 publications in respected journals such as The Canadian Journal of Addiction and The American Journal of Drug and Alcohol Abuse. As founding editor of the Canadian Journal of Addiction, I helped create a platform to share new knowledge and support continuous improvement in patient care. I've also had the privilege of serving on the Board of Directors for the Canadian Society of Addiction Medicine, contributing to the advancement of standards across the field.
Teaching and mentorship have always been deeply rewarding parts of my work. For over a decade, I taught in the Department of Family and Community Medicine at the University of Toronto and mentored medical students through the Family Medicine Mentorship Program. I've been honoured to receive the Faculty of Medicine Teaching Award for the Peters-Boyd Academy in 2003 and 2010, along with several nominations over the years.
"I hope for a system where access to high-quality care is universal—where financial barriers and social factors never stand in the way of well-being."
Looking ahead, my vision for healthcare is simple. I hope for a system where access to high-quality care is universal—where financial barriers and social factors never stand in the way of well-being. I also believe strongly in shifting the focus toward preventative care, helping patients live healthier, fuller lives long before illness ever takes hold.
