Our Story

Cassie DeLuca, co-owner and head coach, dreamed of owning a gym since she took gymnastic classes as a little girl. Cassie was a competitive gymnast at Twin City Twisters in Champlin, MN, reaching the highest levels of the Junior Olympic program. She continued her gymnastics career in college at UW-Stout. Cassie started coaching gymnastics at the age of 14 and hasn’t stopped since.

In 2008 Cassie started up a community education gymnastics program for St. Croix Falls and took over the community ed programs in Amery and Chisago Lakes school districts. She built those programs up to become what we now know as Flex Gymnastics. In 2012 her dream of running a gymnastics club in her own facility became a reality when she and her husband, Ted DeLuca, moved Flex into their first building in St. Croix Falls. With over 40 years of combined gymnastics experience, Flex has brought a variety of developmental and competitive programs to the community's children.

What Customers Say

I've been a gymnastics mom now for over 10 years, and this club wins, hands down. Most clubs focus only on physical training. Flex develops gymnasts holistically. They work on character, sportsmanship, and determination.

Cassie, the owner, and head coach spent her life as a competitive gymnast and understands the importance of mental grit in gymnastics. This is the first club that we've had emphasize this, and it's critical for young athletes.

Beyond that, the facility is new and clean, the coaching staff is warm and personable, and everyone is treated like family.

Elysha Gellerman

Coach Cassie along with all the other great coaches is amazing! The new facility is just unbelievable for the population of our area. The entire Flex staff cares about everyone one of these kids and they employ many of their own gymnasts!

Johnathan Archibald

We went there for a birthday party today and the facility is great! The staff was amazing with all of the kids (including mine, who was very shy and was a little timid to participate). My niece takes classes here and absolutely loves it. I may even sign my son up for classes in the future. Great place, and I highly recommend it.
