Fitness & Fuel Coach for Busy Humans

I help real people build sustainable habits around fitness and nutrition — no extremes, no all-or-nothing mindset. As a firefighter, gym owner, and fire academy instructor, I understand how full life can be. My coaching is designed to meet you where you’re at — whether you’re not sure where to start or just need help following through. If you’ve ever said “I know what to do, I just don’t do it”… or “I don’t even know where to start” — you’re my people. I grew up in a sport that celebrated being small — and I spent years stuck in disordered eating patterns because of it. It took time (and a lot of unlearning), but I’ve learned to care way more about what my body can do than what it weighs. That perspective shapes everything I coach now. Oh — and I have four dogs, each with more personality than most people I know.
