Peter Santos, CF-L2 - Owner

My early career as a Firefighter/EMT is what led me to find CrossFit. I loved the way my new found “functional” fitness program helped me to perform better as a Firefighter and handle the rigors that the job entails.

I earned my Level 1 CrossFit certificate in the summer of 2008 and started training others. I have always had a passion for helping people and had plenty of opportunity as an EMT to treat the sick and injured. Being a CrossFit coach and owning my own affiliate has given me a new opportunity to not only to help the sick and unhealthy, but to be on the preventative side of the spectrum as well.

Establishing good habits through fitness and nutrition and helping people to reach their potential inside and outside of the gym is our mission here at CrossFit Bios. I look forward to helping you whatever your fitness goal may be.
