About Us

Trust The Experts.

Real question time. Would you ever get dental work from a hobby dentist? How about surgery from someone who does it a couple of hours a week after they’ve worked their actual job? Well my friends, that’s what you’re getting at almost every gym and group class in Fargo-Moorhead.

We’re changing the way fitness is done in Fargo-Moorhead. 

No other gym in all of Fargo-Moorhead can say all of their coaches are full-time and certified. We can. Learn more about why that’s important. And more importantly than anything, come in, see us, and get started living the fittest years of your life.

Sara Mozingo
Founder, Owner, And Coach

Sara is the leader at the helm of Icehouse Fit. When she's not deep diving into programming/movement, helping people live their best lives and nerding out about mindset, she can be found sitting in the sunshine out in nature, hiking as many trails as she can find, mountain biking (well as close to it as you can get in North Dakota) and rock climbing with her sidekick Mr. Mosely (her 3 year old pup). Sara does not like to waste a beautiful day and she is happy to use her fitness as often as possible.

Jeremy Gruensteiner
Director Of Operations And Technology

I have always enjoyed helping people, but wasn't always sure what that would look like as a career. I found Icehouse, became certified as a coach, and after my first experience coaching I decided that I wanted to leave my career in technology and make it my purpose to help people transform their lives. When I am not coaching in the gym, I can be found traveling to compete as an Olympic Weightlifter or trying out new strength sports.

Leslie Rumble

My favorite part of being a Coach is watching someone do something that they didn’t think they could do and do it anyways! Seeing them get stronger, healthier and crush their goals is the best! I use fitness and movement to improve my mental health game. Getting my body moving has helped me be a better person, be more present for my family and have more energy! My favorite place to use my fitness is at the lake! Swimming, walking in the woods and yoga on the dock.

Holly Rust


Holly has done a little of this and a little of that throughout her life, from bartending to data crunching desk jobs, and she is happy that her path has led her to coach at Icehouse Fit.  What she loves about coaching is being able to make connections, listen to, encourage, and guide people as they work towards their wellness goals - whatever they might be.  Holly enjoys staying active outside of the gym by hiking, camping, and playing volleyball and softball.


Ashley Rieck

Membership and Mindset Director

 We love to refer to Ashley as our “Cruise Ship Director”. She loves getting to know who our members are outside of “gym life” and what makes them who they are. She also loves to keep us organized, caffeinated and connected. Outside of the gym she can be found creating art in her studio, rock climbing and snuggling her dogs while rewatching Disney movies.
