Our Coaches


Kristen Kostun
Tony Rissley
Co-owners, Head Coaches

Kristen has been involved in CrossFit since 2010.  She became a Level 1 coach the same year and soon followed up with a certification in Olympic Lifting. Coaching friends and other athletes started as a hobby out of a friend’s garage. This hobby quickly turned into a life changing passion and dream. A couple of years later the dream became reality and CrossFit 30518 came to life. Over the years she has participated in several local CrossFit Competitions as well as numerous 5k/10k trail runs and a half marathon.

She originally started working out at a globo gym at the urging of a friend. “Having not participated in sports as a child working out was something that was new to me and very scary”. After about a year she was introduced to CrossFit by another friend. And that as they say was the beginning of the end. “I formed a strong bond with a bunch of girls within the gym. We held each other accountable, made sure we stayed focused. CrossFit turned into my passion. I found something that was fun and helped make the most changes to my body. I became strong, both physically and mentally. Even today CrossFit still challenges me in ways I could have never thought possible”.
