Our History

Don’t let what you cannot do interfere with what you can do.” – John Wooden

This simple quote outlines our core philosophy at Calibrate Sports. Movement is medicine.

As Jerry Seinfeld said, “To me, if life boils down to one thing, it’s movement. To live is to keep moving.

Whether you’re an elite athlete, youth athlete, weekend warrior, or are just trying to move well and stay active, there is a place for you on #TeamCalibr8.

Calibrate Sports was founded by Chris Nissler, a highly-respected reconditioning and athletic development specialist who has worked with numerous professional sports organizations, Division 1 universities, and physicians.

After years of helping elite athletes return from injury and perform at the highest levels of sport, it was Chris’ mission to bring the same level of care to his hometown of Littleton, Colorado. As a lifelong student with a passion for helping others, Chris became frustrated with traditional return to play methods that are common practice around the country. Through extensive collaboration with like-minded professionals around the world, he began to employ performance-based reconditioning models built off of a foundation of athletic development and sports performance.

Calibrate Sports in Historic Downtown Littleton in Colorado, where they have built a team of strength coaches, manual therapists, and movement professionals to implement a truly integrated to health and wellness. The result is a truly unique model and the environment in which people of all ages and activity levels are able to thrive.
