Origin Story
In 2006, parked in my weather Volkswagen Jetta outside of Mt. Greylock High School in Western Massachusetts, I wrote out a vision: to cultivate a multispecialty clinic nestled in the towering peaks of Colorado. This envisionsed practice would offer technology-driven healthcare tailored for athletes striving for peak performance. It would seamlessly blend the raw power of strength training with the fluidity of yoga; merging outdoor adventure with meticulously outlined training regimes, and harmonizing holistic Eastern medicine with Western scientific breakthroughs.
My journey into athletics began conventionally with soccer, baseball and skiing in my youth, evolving into football, freestyle skiing and track & field in high school. College brought competition in varsity football and track & field at Ithaca College, where my love for outdoor adventure deepened during a transformative semester with the National Outdoor Leadership School. Immerse in wilderness medicine, backcountry skiing, desert backpacking, trad climbing and whitewater travel, I found my calling at the intersection of adventure and scientific training.
This epiphany led me to Boulder, Colorado, where I arrived jobless and homeless after graduate school. Fate intervened, guiding me to the Boulder Center for Sports Medicine where I learned how to properly bike fit under the legendary Andy Pruitt and Dr. Jason Glowney, Charles VanAtta, Sean Madsen, Tim Hilden, and Sue Nakaoka. Mentored by these icons, I honed my skills in cycling and running biomechanics, athletic performance, dry needling and physical therapy before the pandemic redirected my path.
My wife and I decided to embrace a new chapter in Summit County, where the mountains had long been our sanctuary. Joining Howard Head Sports Medicine, I embarked on crafting their bike fit program, all the while continuing to grow as a clinician and high alpine resident. Then the time came when my vision found its truest expression and Summit Sports Lab was born.
