  I'm so thankful that I am able to have a conversation with Dr Twyman and he seems so willing to educate.  I trust his knowledge and willingness to offer input but do so in a collaborative way.  If I have a question, he is always willing to stop and provide feedback so that I understand the options for treatment, diet, supplements etc.

  I had a great experience with Dr. Twyan and his staff.  After years of paranoia about my heart health and not getting any meaningful insight or attempts to find out what was really going on from my primary care physician and another neurologist he referred me to, Dr. Twyman was able to do a deep dive and give me a clear assessment of my heart and overall cardio health.  It turns out my primary care physician was treating me with medication out of an abundance of caution without every finding the root cause of an episode I had years ago that turned out to be something not even related to my heart.  The process with Dr. Twyman gave me peace of mind and I was able to discontinue a statin I was on because I didn't even need it.  He was also able to guide me on some nutrition deficiencies I had so now I know hos to optimize my heart health.  The genetic test was revealing as well, and now I know what to watch out for. Incredibly grateful to Dr. Twyman and his team for their professionalism and guidance.  I highly recommend seeing him if you're looking for real answers to your heart health.

  Dr Twyman is an incredible cardiologist who takes the time to understand what is going on with your body using a comprehensive set of tests combined with a discussion about your lifestyle. He'll then tailor a solution to your specific needs and comfort level with different types of interventions. I couldn't recommend his practice more.

  I have been a patient of Dr. Twyman's for many years, and I cannot recommend him highly enough. He is, without question, one of the most knowledgeable physicians I have ever met. What sets him apart is not only his expertise but also the genuine care and attention he gives to his patients. He always takes the time to answer all of my questions thoroughly, and I have never once felt rushed or like I was an inconvenience. I truly believe that Dr. Twyman has made a profound difference in both the quality and longevity of my life. His dedication, compassion, and commitment to his patients are exceptional, and I am incredibly grateful to have him as my physician.

  I think Dr. Twyman is one of the best preventative cardiologists in the country. His knowledge is astounding, but his interactions with you as the patient are what really set him apart. Dr. Twyman never gets frustrated with the many, many questions I have for him, and he always takes the time to respond. He put a lot of thought into where he located his office to make it easy for his traveling patients. This includes a nearby hotel, nearby restaurants, a mall, and a nearby place for dinner the night before the procedure (if you are flying in). Cassidy and Dao keep everything humming, and they are soon to expand their office to make it more comfortable.

  Dr Twyman has been my cardiologist for over 10 years.  I wanted a provider to guide me through preventive medicine instead of treating something tragic after it happens. His knowledge is incredible and is up to date on the latest cardiovascular research. If you want a brilliant, forward-thinking physician who utilizes cutting-edge science to protect your heart, this clinic is the one.  Office staff is amazing!  They perform many tests in the office, but will accommodate if you need them completed elsewhere for insurance purposes.

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
Your personalized prevention plan

Advanced imaging (if recommended)
CT Coronary Calcium Scan · Cleerly CT Coronary Angiogram · Echocardiogram
Arranged at a nearby imaging center; billed directly to you

Apollo Cardiology is the right fit if:

· 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.

Meet the team

Cassidy — Your first contact and onboarding guide. Cassidy handles scheduling, answers questions before your visit, and makes sure you feel prepared.

Dao — Your vascular testing specialist. You will spend the first part of the office visit with her getting your head to toe vascular assessment
