About
At Healthspan Medical in Sioux Falls, a physician-led team delivers longevity medicine grounded in early detection, advanced diagnostics, and personalized intervention. The practice focuses on healthspan rather than lifespan. That distinction shapes every clinical decision the team makes. Dr. Cassie Hajek leads physician care, bringing expertise in internal medicine, medical genetics, and preventive medicine. An advisory board of six specialists spanning ophthalmology, gynecology, cardiology, surgery, and biotech strengthens the clinical foundation. The multidisciplinary team also includes a physical therapist, registered dietitian, and clinical nurses. Healthspan Medical offers two membership tiers: Snapshot, a one-time comprehensive evaluation, and Foundation, an ongoing longitudinal partnership. Evaluations cover advanced biomarkers, whole-body MRI, genetic testing, movement analysis, neurocognitive testing, and more. The practice keeps its patient panel intentionally small to ensure each member receives focused, longitudinal care. Healthspan Medical does not replace primary care or emergency services; it works alongside them.
