I live in Green Bay, but I do know that East De Pere Schools are supposed to be particularly good. One of my husband's colleagues moved to Ledgeview just so that their children could go to East De Pere High School--I think for their music program. There is also the new Wisconsin International School that just opened near St. Norbert's this year and it is supposed to be fantastic (starting in preschool and working through the international baccalaureate program). I've heard Wrightstown schools are also good. Another good daycare, where my children go, is Encompass Education and Care. They are a non-profit daycare (with numerous locations--there is one in De Pere) that is nationally certified through NAEYC (National Association of Education of the Young Child). The CP Center in Allouez (right off of 172) has an inclusive daycare that is also certified.
There are several trails around in the area. Our family particularly likes the Fox River Trail and the East River Trail. I know there are some further south too. Near and in De Pere, we like Voyageur Park and one a little further north on the river (near a Dairy Queen), Greene Park in Allouez, and other parks in Green Bay. If you are looking for a doctor, there is a pediatric clinic on Red Bird Circle in De Pere (also where my kids go), with several docs that we have found to be terrific.
We've been in the area about 10 years and have really tried to get to know the area for what we are interested in, in particular. If you have any other questions, feel free to email.
