"This isn't just what I do… it's who I had to become."
From a chubby kid in Austria… to a Hollywood fitness model… to becoming a longevity expert helping thousands reclaim their health.
My Journey Didn’t Start in a Gym. It Started With Rejection.
I was 12 years old. Overweight. Insecure. My classmates found a note I wrote to a girl I liked and read it out loud. She looked at me and said:
That moment changed everything. What started as humiliation became obsession.
For over 25 years I’ve studied fat loss, muscle, nutrition, performance, and longevity. From Austria… to Hollywood… to coaching clients across the country.
I didn’t just transform my body. I built a system to help others transform theirs.
