Meet Your Coach & Founder

"I’m not here to just make you fast—I’m here to make you durable."

Triathlon changed my life. It’s more than just a swim, a bike, and a run; it’s a masterclass in discipline, community, and finding out what you’re truly made of when the miles get heavy. Now, I’m here to pass that on.

My approach at Tinman Training & Nutrition is simple: Train smarter. Win longer.

I’ve spent the last 5+ years in the trenches, racing everything from local sprints to full-distance IRONMAN events. I’ve qualified for USA Triathlon Nationals and World Championships, but the real lessons weren’t learned on the podiums—they were learned on the hard courses and through the "hard way" mistakes that every athlete faces.

What you get when we work together:

A PT-Driven Approach: With a background in Health Science and multiple certifications, I combine a pro-level mindset with science-backed wellness and nutrition.

Real-World Experience: No fluff. My coaching is built on years of racing and coaching real athletes through real challenges.

A Focus on Potential: I have a passion for unlocking the power people don’t even know they have yet.

In this sport, consistency is everything. If you're ready to build a body that lasts and a mindset that wins, let’s get to work.
