Birthday Bash!

Book your child's next party at Junior Gym!  It will be a party your child won't soon forget.  And you'll love it too because we make it so easy.  You and your guests will have the whole facility to yourselves, and our staff will take care of everything.  We lead activities and games in the gym, serve the food, cut the cake, and even help carry gifts to the car.  Our spacious facility is the perfect place for the kids to play and celebrate while the adults get to relax and enjoy.
