  • “20 mile has been a great impact on my daughter. Greatest level 4 coaching I have seen in a few years. My daughter has excelled in every area she has trained in. She is having fun but working hard!!”

  • “Our kids have been a part of 20 MAC since 2009. When you become part of this gym – you are part of a FAMILY. This facility doesn’t just promote that type of environment though – they demonstrate that in EVERYTHING they do with these kids. Over the last 4 years we’ve experienced summers filled with team outings to amusement parks, swimming pools and family BBQ’s; to winters random celebrations and holiday parties. The coaches are exceptional. They are not only producing elite gymnasts, but also instruct these kids on life skills;self respect, support & respect for their team, discipline to work hard and the importance of being considerate to others. The coaches are always accessible and communicate constantly with parents, keeping us informed of any challenges our kids may be experiencing and goals they may have set. This is a supportive community that we are proud to be a part of, that our kids love to attend, and that we encourage anyone looking for a place to call home – to join.”
