    We just had my 4 year old girls party at Jumpnasium for the 2nd year in a row and we had such a great time! The party coaches were very friendly and helpful. This place is one of the best kept secrets for having awesome parties. Trust me, my daughter loves it and so does her friends!

    My kids love this place. It's fun for them and safe because they have staff that watches each station to keep kids out of trouble. Birthday parties are well organized too. And they keep the place clean. Perfect place to retreat to on rainy days.
