💪 Evidence-Based Coaching

Training That Actually Works

Evidence-based programs, peptide-informed protocols, and AI-powered tracking. I rebuilt myself from a TBI — now I help others transform.

Why I Coach

A traumatic brain injury changed everything. One moment I was living my life; the next, I was starting over from zero. Physically broken. Mentally foggy. The kind of setback that makes most people question whether they'll ever feel normal again.

I didn't just want normal. I wanted stronger.

Recovery taught me something most people never learn the hard way: your body is an incredibly adaptive machine when you give it the right inputs. I went deep into evidence-based training, peptide science, and hormonal optimization. Piece by piece, I rebuilt myself — stronger than before the injury.

Now I help others do the same.
