Founding Team

Darren Bounds
CEO & Co-Founder

As someone having the lifelong autoimmune disease, ulcerative colitis, Darren was inspired to co-found Trusted Therapies to give fellow patients access to expert doctors so that patients can get detailed, accurate information about their diseases and the therapies available.

A 10-year career in the pharmaceutical industry enabled him to work with world-renowned doctors on educational programs for other doctors. It was at these programs on Crohn’s and ulcerative colitis that Darren saw the wealth of information that they had access to. He wished his fellow patients could also have the privilege of tapping into the minds of the experts.

His wish came true when he partnered with Dr. Brian Bressler and left his career in the pharmaceutical industry to start Trusted Therapies.

Darren studied molecular biology and biochemistry at Simon Fraser University.
