My son joined the Soccer Tots program last spring. They offer league play as well as the instructional Soccer Tots. There are also spring and fall leagues. It seems to be a very well run organization and fees are reasonable.
My only complaint is that Soccer Tot coaches are volunteers with no experience required! My son's team did not get the instruction I observed other teams getting. I'm confident the older ages and more advanced teams have very qualified coaches.
The main field location is at Northwestway park complete with a snack bar and awesome playground.
