Justin Williams

Owner, Coach, Personal Trainer

I was born and raised in Billings MT where I grew up competing in gymnastics, football, basketball, baseball and track & field. After high school sports, finding something to feed my competitiveness was hard, until I was introduced to CrossFit in 2009. I fell in love instantly with the competitiveness and community CrossFit offered.

I got my level 1 CrossFit cert in 2018 and have coached at multiple gyms in Billings helping members work towards their goals and break down barriers as well as running a gym with my wife in beautiful Costa Rica. Since taking over Iron Den in 2021 I have been fortunate to meet some of the most amazing people and look forward to growing our great community!
