John M. Bryant, Founder and Head Coach

John is a lifelong endurance athlete who tried CrossFit in early 2010, and was hooked immediately. Having never recovered from the endurance bug, however, he has used CrossFit to complete the Twin Cities Marathon (twice) and expand his bicycle racing to include the muddy joys of cyclocross.

He is a licensed attorney and served for six years in the United States Marine Corps.  He is excited to help you discover and achieve your health and fitness goals.

Bryan Rosen, Coach/Trainer

“Since I was young, I was involved in sports. I played baseball and soccer, and participated in gymnastics and diving. My favorite part about doing team sports is knowing the fact that your teammates are going through what you’re going through, and therefore have your back. To me, CrossFit is more than a strength and conditioning program, it’s about putting passion into being disciplined, teamwork, and most importantly being healthy. I found CrossFit in the fall of 2009. At the time, it was just a fun way to workout. Little did I know that it would shape the way I view health and fitness. My main purpose for doing CrossFit these days is to be a better coach by helping others be their best selves.”

Mike Laninga, Coach/Trainer

After 18 months of being a member at Slipstream, Mike decided he wanted to be a CrossFit coach. 
“Slipstream and the sport of CrossFit has been such a positive influence on my overall health and well-being. Not only did I want to learn more about how the body moves and functions, but I want to help other people reach their goals and become better versions of themselves.”
Mike is a lifelong athlete and was a NCAA D-I track and field sprinter for Ball State University competing in the 400-meter dash. He also coached high school track for two years and helped produce an Illinois state champion in the 800-meter run. 
Outside of the gym, Mike hosts a local podcast, enjoys track workouts, and loves listening to reggae music.
