Finally, a cardiologist who investigates — not just prescribes.
Most cardiologists see you for 10 minutes and hand you a statin. Dr. Twyman spends an hour with you, runs advanced genetic and vascular testing, and builds a prevention plan around your actual biology — not a population average.
Patients fly in from California, Florida, Arizona, New Jersey, and the furthest is from Australia. Many have been coming back for 10 or 15 years. Here’s how it works.
The 2-Part Deep Dive
Your first visit is unlike any cardiology appointment you’ve had. Plan for 2.5–3 hours. We run everything in-office — no sending you somewhere else, no waiting weeks for results.
Part 1 — Initial visit (in-person, St. Louis)
1-hour consultation with Dr. Twyman
Comprehensive non-invasive arterial testing
Advanced lab work drawn at our in-office lab
Part 2 — Results review (in-person or Zoom)
1-hour deep dive into your results
Dr. Twyman walks you through exactly what we found and why it matters

· You have a family history of heart disease and want to know your true risk — not just your cholesterol
· You’ve been told your labs are “normal” but something feels off
· You’ve been recommended statins and want to understand whether you actually need them
· You’re proactive about your health and frustrated with 10-minute checkups
· You’re healthy and want to stay that way
We are not currently the right fit for patients whose primary concern is a heart arrhythmia, or for patients seeking insurance-covered care. Our practice does not accept insurance and has opted out of Medicare.
