“Cheerleading at Fierce as made an amazing difference in my daughter’s life. After trying many different sports and activities, our daughter started tumbling and cheer at Fierce at the “late” age of 12. Feeling awkward and behind with barely a cartwheel, I was unsure of how long this new sport would last for her. However, the progress she made in tumbling and learning to fly in a very short time was amazing thanks to the coaches at this gym. She joined a competition team within weeks of joining the program and felt she finally found where she belonged. As parents, there is no better feeling then seeing your kid find her passion and have success with it” “having two children in the Fierce program for the past several years, has been the best decision we have made for our kids. All of the coaches and staff, not just my children’s direct coaches, have a vested interest in our kids. This program helps to raise amazing athletes as well as well rounded individuals. Shelby Magelsen and her staff have given both of our girls the confidence they need to be successful people in and outside of the gym. Our kids look up to their coaches and we are grateful for their guidance in their lives. Fierce is family, not just a gym” “Our youngest daughter started tumbling at Fierce at 3 years old. We have always offered her additional activities but 4 years later she is 100% committed to her team and coaches at this gym. She has experienced a “mental block” set back but the staff at Fierce has been dedicated to working her through it without negativity and pressure. They believe in positive coaching and their communication with our child as well as with us parents has been greatly appreciated in getting us through this challenge. The staff is continually educated on how to be the best trainers for these young athletes and it shows” Clark family
