“My son and I attended a Private Playdate party at CMOSC on Saturday and we had an absolute wonderful time!  Loved the private setting and being able to have the space just to our group.  My son wants to do the same for his birthday, so now we’re just waiting for the Party Calendar to open up online for future dates.  We’re looking forward to it!

Such a wonderful place you guys make available to the kids!”
