Patti’s Play Center provides a nurturing and well-supervised social environment where children are encouraged to develop new friendships and explore interests at their own pace. Offering part-time childcare programs for 2–4 year olds, Patti’s Play Center fills a unique niche. Patti’s is not a daycare or a preschool, but a structured play center designed to both prepare young children for their first preschool experience, and complement an older child’s preschool schedule.
