Was absolutely an incredible venue to host our five-year-old's birthday. The staff were super friendly and made organizing and executing the party seamless. Would 100% recommend having your child's birthday here!
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!
We just had my daughter’s 2nd birthday party here and it did not disappoint! The staff were super friendly and efficient, the play areas were safe and age appropriate for littles and overall the facilities were immaculate. I highly recommend.
Love Smartiepants so much!!! Of all the classes I took my son to he adored it the most! Very interactive, engaging with different developmental elements! I especially loved Jo the teacher, she was very outgoing, fun and had a great energy! Please open more locations around St. Clair West! ❤️
I’ve been going to smartiegym with my son since he was 1, he is now 2.5 and I am always sure to be ready to register for the next sessions available. It’s truly his happy place he LOVES to run play interact and the teachers are beyond! We love it I can’t recommend it enough as a wonderful place to go for drop-in play or do class our personal favourite is smartie movers at smartiegym but all classes are just a wonderful place for your child to spend time learn and grow ❤️
