Jesus : Coach



I come to One World all the way from the East Coast, originally from Boston, MA. I started doing Crossfit in Djibouti Africa three years ago. I didn't play too many sports or work out at all, but I needed an all-encompassing fitness program and Crossfit fit the need perfectly. When I returned from my deployment I needed to find a gym closer to home and One World was down the street!

Being so far from home, I appreciate the community and group of friends that I have made at One World. It's a great second family and I love coming there every day! Currently I work in the Rescue Wing at Moffett Field in the United States Air Force. I have served for ten years and I recently obtained the rank of Master Sergeant. I obtained my Crossfit Level 1 trainer certificate in May 2016 and I am excited to help my fellow gym members in any way possible!

Chris “DieHard” M : coach



Originally from the Pacific North West, I have played sports at various levels ending at Oregon State University. Through sports I have learned “Strength is King and Conditioning is the Queen”. In order to tap your true potential one must equally coincide with the other.

I started my Crossfit journey in 2012 and know I still have a long ways to go but I love and embrace every challenge that I encounter. If I can help anyone with their journey into a fitter/stronger lifestyle I personally feel it is an honor to be involved with your journey.

Chris "DieHard" coaches the Bootcamp Barbell Club on Tuesday’s and Thursday’s @ 6pm.
