I started life as a strength and conditioning coach. Worked at a couple D1 schools, then left because I couldn't feed myself on the salary.
Went to work for Medically based fitness facility as the director of personal training. Basically, it was a gym owned by a hospital, so we had regular memberships, but also direct referrals from the hospital for injury/surgical rehabilitation. I had a staff of 18 certified trainers and therapists, and oversaw everything from pay to budget to program development. We also provided lectures to the community on fitness.
After a while, I decided bad hours and a complete lack of appreciation for my life-risking efforts would be more fulfilling, so the police I became!
