Boost Performance and Longevity Center is a concierge medicine and performance optimization practice in Lakeway, Texas, serving patients throughout the Austin Hill Country. Founded by Dr. Steven Conroy, a board-certified Emergency Medicine physician with nearly two decades of clinical experience, the center is built on a conviction that the most powerful medicine is preventative, integrative, and early. Dr. Conroy's years in high-acuity emergency departments across Pennsylvania and Texas showed him firsthand the devastating physical and human cost of preventable disease — and drove him to create a practice designed to intervene long before crisis arrives. The result is a physician-led environment where advanced testing, personalized care protocols, and evidence-based longevity strategies meet real accountability and long-term partnership between patient and physician.

About the Practice

Dr. Steven Conroy is a board-certified Emergency Medicine physician who spent fifteen-plus years working in emergency departments at leading hospitals across Pennsylvania and Texas. Witnessing the downstream consequences of untreated cardiovascular disease, metabolic dysfunction, and lifestyle-related illness, he pursued advanced training in functional and integrative medicine — disciplines that address the upstream drivers of the conditions he spent his career treating acutely. Dr. Conroy leads by example. He is an elite endurance athlete who has completed eleven 70.3 IRONMAN triathlons and four full IRONMANs, including both the World Championships in Nice, France and in Kona, Hawai'i. That record reflects not just athletic accomplishment but a deep, practiced understanding of performance physiology, recovery, and the long-term habits that sustain exceptional health. The Center's team includes Maggi Finley, a Precision Nutrition-certified coach and IRONMAN World Championship finisher, and two registered nurses with emergency medicine backgrounds who specialize in IV therapy — a team built around performance from the inside out.
