About ClearCardio®
ClearCardio® wasn't created to fit into the current medical system. It was created to replace it — and to save 10 million lives over the next 10 years.
The mission
Heart disease is the #1 killer in America precisely because the system waits for symptoms. We invert the model: detect the disease in its silent phase with 640-slice CCTA + FDA-cleared AI, and treat it with a personalized, physician-led plan — long before it ever causes a symptom. Because heart disease is largely genetic, measurable, and in many cases largely preventable.
"End heart attacks and strokes as we know them — one precisely measured artery at a time."
Meet Dr. John Osborne, MD, PhD — your preventive cardiologist
Dr. John Osborne is the architect behind ClearCardio's “living autopsy” approach to heart and stroke prevention. He's not an influencer who read a few studies. He's a Harvard-trained cardiologist, a PhD cardiovascular physiologist, and a fellow of both the American College of Cardiology and the National Lipid Association who has spent three decades doing one thing: figuring out how to see and reverse artery disease before it kills people. After graduating magna cum laude in medicine and earning a PhD in cardiovascular physiology, he completed his internal medicine and cardiology training at Brigham and Women's Hospital and Harvard Medical School, then went deeper with post-doctoral work in the molecular genetics of inherited heart disease.
Early in his career he saw the same pattern over and over: people only found out they had heart disease in the cath lab or the ER — when the damage was already done. That pushed him away from mechanical fixes and toward aggressive, data-driven prevention. He became one of the early pioneers of cardiac CT and non-invasive plaque imaging, leading one of the first freestanding 256-slice CT programs in North America and later overseeing installation of the first 640-slice ATLAS system in the United States. Today, as Chief Medical Officer, he reviews patients' CT and AI analyses, designs the treatment playbooks our physicians use, and teaches so more people understand that plaque can be seen, measured and driven into retreat. He hasn't performed a diagnostic heart catheterization in over 20 years — his goal is to make sure you never need one.
Our Team
Your images and your metabolism are read by two specialists who work from the same chart — because plaque is built by both.
Chief Medical Officer
Harvard-trained preventive cardiologist and PhD cardiovascular physiologist. He designs the imaging and treatment playbooks our physicians follow, and reviews the complex cases himself.

Endocrinologist — Cardiometabolic & Men's Health
Board-Certified Endocrinologist with 20+ years treating the metabolic and hormonal drivers of plaque — diabetes, lipids, thyroid, and men's health — by telemedicine since 2006.
Read full bio →The system is built to react — not prevent
The modern medical system is built to react, not prevent. Most cardiologists are trained — and reimbursed — to intervene after symptoms appear, not to find disease in its silent phase. So the system's attention and resources concentrate on late-stage procedures:
Each costs tens of thousands of dollars. But by then the disease is already advanced — and the root cause, microscopic rupture-prone plaque, has been ignored the whole time.
are board-certified in lipidology AND hypertension — the expertise you need to detect and treat disease early.
are trained and certified to read and interpret coronary CT angiograms (CCTA) — the high-resolution heart scan that can catch this plaque before symptoms appear.
Even well-intentioned doctors may rely on tests that were never designed to find early soft plaque. If you've been told to "wait and see" based on a stress test, the most important question — what's actually in your arteries — is still unanswered.

"Let's treat the root cause."
Four cardiologists in a row told him he needed stents or bypass surgery. He had no symptoms. He wanted a 21st-century answer, not a 20th-century reflex.

His father had a heart attack at 45 and needed a triple bypass. Kerry was now the same age, 220 pounds, and being told by the system that he was fine.

One visit in person. Ongoing prevention by telehealth.
Wherever you live, you can apply to join ClearCardio's patent-pending prevention program. You'll start with a single on-site visit at one of our clinics, then continue your care through structured telehealth visits, virtual coaching and remote monitoring designed to track and treat plaque over time.
With 30 years of preventative cardiology, 25,000 evaluations over 21 years and a proven process, you're in excellent hands. On your Patient Assessment Call we'll review your history and goals, explain how travel and telehealth would work for you, and make sure the program is a good fit before you commit.
