Hi, I'm Tim. I'm a CF Warrior, personal trainer, nutritionist, father, author of The CF Warrior Code, and I'm here to help you better understand CF and how to manage it to be healthy and happy.

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.
