Parent & Toddler

Spend your Saturday mornings giving your child a safe and gentle introduction to preschool through our Saturday parent and child class.



Our separating two's program provides an optimal first school experience for children ages 2.5 and older.



Children learn through play, as they acclimate to the school environment and create a strong foundation for all future learning endeavors. 



Children in our pre-k program continue to learn through play as they develop the skills and concepts necessary to master language, literacy, math, and science.

What Parents Think

"I cannot say enough to praise the developmentally sensitive, creative and innovative preschool programs offered at the Co-op. The director and teachers are attentive, warm, approachable, smart, experienced, and exceptionally aware of the emotional and learning needs of preschoolers. We began this school year with a child who had serious separation issues, and no other program in our entire county came close to providing the safe, nurturing environment that the Co-op provides. In a culture of over-academic preschool programs, the Co-op encourages learning through play and exploration in an environment of safety and understanding of the individual needs of each child."
