Justin Roethlingshoefer

Founder

Justin Roethlingshoefer is a human performance expert, data-driven health strategist, and longevity practitioner with over two decades of experience optimizing health and performance. His mission is simple yet profound: to empower, educate, and equip leaders to take ownership of their health so they can fully live out their God-given mission.

As a former health and performance expert in the NCAA and NHL, Justin used biometric data and real-time analytics to enhance recovery, endurance, and longevity. But his own wake-up call came when he was told he wouldn’t live past 35. Forced to reprioritize his own health, he embarked on a personal healing journey using the same methods he was using for his athletes—one that led to a powerful realization: the health crisis wasn’t just an athlete issue; it was a human issue.

The real problem? Healthcare was reactive, not proactive. The system focused on treating symptoms rather than asking the right question: “Why is this happening?” Determined to bring wisdom out of the dark and into the light, Justin made it his mission to spread a message of hope and healing that unlocked the truth about health and longevity—not just for the elite, but for everyone.

This journey led him to create OWN IT, an elite health coaching ecosystem designed for leaders who refuse to accept mediocrity in any aspect of life. Through personalized data, a team of specialized experts, and a science-backed system, OWN IT has helped thousands heal and optimize their mind, body, and spirit—unlocking the unstoppable energy and healing they were built for.

A sought-after speaker, consultant, USA Today bestselling author, and podcast host of the OWN IT show, Justin doesn’t just teach high performers how to improve their health—he gives them the blueprint to win. His work is shifting the conversation from reactive healthcare to proactive health ownership, proving that longevity isn’t just about adding years to your life, but adding life to your years.

But beyond the data, science, and accolades, Justin is a husband, a man of faith, and a firm believer in this truth:

Healing is coming to you. Thriving is waiting for you. But it requires you to live differently
