What Our Parents Say About Us

{I took my 1.5 year old to class at Athletic Adventures Activity Center and he had a blast! The gym is super clean, the coach (Coach Al ) is amazing and Debbie at the front desk was super warm and welcoming! I highly recommend this great business!
{Had a wonderful time taking my two kids to open gym on Friday. The teachers were there the entire time and my kids were exhausted by the end of it! Highly recommend
{Fun environment with friendly coaches for our little toddler! Especially love the open gym class opportunities to let him run off energy in a safe environment on bad weather days! UPDATE: Loving this time more and more. Friday and Sunday 1030am to Noon and you can just use a punch card so you don't have to commit to every session!
{We love this place! We’ve signed our kid up for a couple different classes, but the ninja classes have been her favorite. The parent night out events are always a hit! The coaches she’s had have all been great, but Coach Charlie has been her absolute fave. He’s super fun, great with building confidence, and knows how to keep the kids attentive with boundaries and patience. Video is from their Holiday party. It was a blast!
{Athletic Adventures Sports Center is sure to be one of the premier facilities in our area. Kassie Haag is one of the best in the industry and now she is starting her own gym! Her passion for providing a safe environment for your child to reach their full athletic potential is evident with each choice she makes. Kassie had an enormously positive impact on both of my competitive gymnast daughters when they were under her instruction. I am excited about Kassie Haag's next professional endeavor - and how lucky we are that it is in our area!
