Our Executives

We're a healthcare company that brings site experience, product development expertise and health system management experience to the challenge of transforming clinical research for patients and doctors everywhere.


Our founder and CEO, cardiologist Dr. Irfan Khan served as a principal investigator for more than a decade before starting Circuit Clinical. Our CTO David Hicks is the co-founder and former CIO of Healthgrades and our CMO Dr. Richard Ruh has served as both VP Service Lines for a large accountable care organization as well as managing partner in his group practice. We believe bringing these unique viewpoints together is essential in delivering clinical research to where it matters most to patients - their own doctors' offices.
