Strength is not
what happened to you.It is what you built next.

I write, coach, and create honest spaces for rebuilding trust in yourself through strength, nutrition, and the words we need when life changes.

01 / Story

This is the real version

I did not become strong because life was easy.

I became strong because, more than once, I needed somewhere to put the pain.

Depression in 2016. An eating disorder in 2017. Cancer in 2023. Those are facts, but they are not the whole story. The whole story is also a barbell, a blank page, a plane ticket, a new identity, and the slow decision to stay.

Today, I use everything I learned to help people build strength that looks like them. Not punishment or perfection, but a life they can actually inhabit.

Cancer changed the shape of every plan I had made.

052023

National Powerlifting Champion. Proof that strength can be rewritten.
