Quick Facts About Me

  • ​I was diagnosed with cystic fibrosis at just 2 years old. My parents were told I wouldn’t live past 10. But limits have never defined me—grit has.

  • I’m a double lung and kidney transplant survivor, NYC Marathon finisher, Mr. CT bodybuilding champion, certified personal trainer, and nutrition expert with over 25 years of experience and 50,000+ client hours.

  • I’m a certified personal trainer through ACE, NSCA, NASM, and CSCS.

  • I created the revolutionary HIIT + PAUSE system for airway clearance.

  • When I was 26, I became a pro bodybuilder and won the CT State Men's title.

  • At 32, after undergoing a life-saving double lung transplant, I was in the ICU and made my surgeon a bold promise: “Give me a year, and we’ll cross the finish line at the New York City Marathon—together.”​ Less than 12 months later, defying the odds, we did exactly that.

  • In 2019, after battling end stage kidney disease brought on by the same medications that protected my new lungs, I underwent a kidney transplant.
