Who We Are
Rocket Doctor is a rapidly growing digital health marketplace that provides comprehensive patient care virtually. We connect patients with board-certified physicians of all disciplines through our proprietary tech platform. Founded in Toronto, the service has cared for over 30,000 patients. Our virtual clinic expands beyond Ontario to service Alberta, BC and most recently California, USA.


Our Mission
We believe healthcare is a basic human right and not a privilege for those with money and connections. Everyone should have access to affordable high-quality care. Rocket Doctor is on a mission to make high-quality healthcare affordable, accessible, quick and convenient for everyone, but especially those living in underserved communities.
We do this by empowering doctors to run their own virtual practice through an efficient and automated platform, while extending the breadth of services offered by sending the most advanced doctor’s office directly to patients.
