MY STORY

I was 260 lbs. Then everything changed.

As a teenager I weighed 260 pounds. I struggled with my confidence, my relationship with food, and the feeling that I was stuck. I had to figure it all out the hard way — alone.

Over time I lost more than 100 pounds and completely rebuilt my lifestyle. Today I'm a NASM-CPT, a former Division 1 athlete, and I compete in marathons and triathlons. The same principles that transformed me are the foundation of how I coach you.

My approach is built on simplicity, structure, and accountability — because lasting change isn't about a quick fix. It's about becoming a different person.

THE FOUR PILLARS

Built on what actually works.

Real results don't come from one workout or one diet. They come from stacking the four things that change everything.

Fitness

Custom workout plans built for your level, your equipment, and your schedule. Train smarter, not harder.

Nutrition

Simple, sustainable nutrition guidance — no crash diets, no banned foods. Just habits that actually stick.

Mindset

Build the discipline, confidence, and identity of someone who follows through. The body follows the mind.

Relationship with Food

Heal the all-or-nothing cycle. Learn to enjoy food without guilt while still hitting your goals.
