Our family loves SmartieGym! I started taking my son to classes at the gym when he was 4 months old. The teachers are amazing and the facility is super clean. Now that he is a toddler, we love dropping-in to play. I highly recommend both the classes and drop-in programming.
We hosted by daughter’s 4th birthday party at SmartieGym and the experience was excellent from start to finish. The team was so helpful, organized and overall wonderful. So many small details were considered that helped make the whole process seamless and my daughter and her friends had the best time! Highly recommend!
This was our second year celebrating our daughter's birthday at SmartieGym St. Clair and once again they exceeded our expectations. We've done both the Smartie Artists and Smartie Scientists activities and both were absolutely phenomenal. What sets SmartieGym apart is that it's so much more than a typical indoor playground where kids just run around aimlessly. They still get plenty of time to burn off energy, but the structured activities, games, dancing, and themed experiences make the party so much more memorable - I can't recommend SmartieGym St. Clair enough!
Bright, clean space. Friendly and engaging staff. Great for drop-in play!
Amazing experience with my baby's first birthday party! The staff are fantastic and take care of everything during the party so the parents could enjoy it too. Lots of play options for kids of all ages, and an engaging and well-paced music circle to ground the party before food/cake. Just a great setup and amazing execution. Thank you for everything!
