ABOUT ME

Guided by real experience

I'm Sean O'Brien. Fourteen years of rebuilding myself — from 60 pounds overweight, addicted, and homeless, to fit, focused, and thriving. Nearly four years as a certified trainer, helping others do what I did. I know the hard road because I walked it. Let me help you walk yours.
