At HormoneSynergy®, we focus on identifying risk early, optimizing physiology, and building long-term health through a structured, physician-guided approach. This is not reactive medicine. It is a proactive model designed to detect, measure, and improve the systems that drive aging, performance, and disease risk.

We serve patients in Portland, Lake Oswego, and across the United States through a combination of in-clinic diagnostics and guided care.

HormoneSynergy® is a physician-led longevity medicine clinic in Portland, Oregon specializing in preventive cardiology, metabolic health, hormone optimization, and advanced diagnostic testing. Our approach focuses on early detection of disease risk and personalized, evidence-based prevention strategies.

Cardiovascular disease often develops silently for years before symptoms appear. With more than 25 years of clinical experience in preventive cardiology, Dr. Kathryn Retzler uses advanced imaging, vascular testing, and targeted diagnostics—including Cleerly®-enabled Coronary CT Angiography (CCTA)—to directly visualize coronary plaque and more accurately assess cardiovascular risk.

Rather than relying on indirect markers or late-stage detection, the focus is early identification, precise risk assessment, and proactive care—supporting long-term cardiovascular health and longevity.
