PDO is a fantastic experience for toddlers being introduced to school. Karen is a warm and loving teacher who truly enjoys being around and raising children. This is a co-op so one parent works with Karen each day. My two girls both started at PDO and still talk and visit Karen often. The room is big, has a large playroom in the bright basement and in the warmer months, they go out in wagons to the park. We are very lucky to have had both girls start their school adventure at PDO.
