As a transplant cardiologist at Brigham & Women’s Hospital and Harvard Medical School, I helped care for a thousand or so severely ill patients. As an entrepreneur, I have impacted the lives of more than 100 million people, including millions that are underserved by health systems around the world.

I’m hopeful that my best is yet to come.

That would be Wellcoin, my new venture. Wellcoin is based on a terrific idea, but I can’t tell you more than that right now. Please bear with me!

Before starting Wellcoin, I served as the Senior VP for Clinical Affairs at Practice Fusion, which offers a Web-based electronic health record for free to providers. I helped Practice Fusion grow from a very early stage into a leader in the ambulatory EHR marketplace. The company now has more than 130,000 users and 25 million patient records in its cloud. It recently closed a $23 million Series B investment with Peter Theil’s Founder Fund.

Prior to that, I was the Founder and CEO of Clinical Solutions. We produced customizable algorithmic content that nurses used to triage callers who had developed new medical symptoms. Clinical Solutions was acquired in 2006 by CAS Services (UK) at a time when more than 70 million people in several countries could access our algorithms using a toll-free number.

I haven’t always been an entrepreneur. In addition to serving as an attending physician in the heart transplantation program at the Brigham, I have founded a peer-reviewed journal and consulted to clients in several countries on matters of organizational performance and the quality of care. In the latter role, I have advised the Robert Wood Johnson Foundation, the British National Health Service (NHS), Abbott Laboratories, Flybridge Capital Partners and Dragonvest Partners, among others. I’m also a mentor at Rock Health.

Long ago, I completed an internal medicine residency and a cardiovascular disease fellowship at the Brigham, and earned a PhD in Health Policy and Management from MIT.

I enjoy travel, photography, modern art, working-out and jazz. I voted for George McGovern. I am the father of 3 accomplished women. And notably, I have survived for 30 years as a Yankee fan while living in enemy territory.
