Educational Philosophy

As career kindergarten teachers, it's been our experience that incoming 5-year-olds are lacking in preparatory academic fundamentals and social cues. Mrs. O's directors will prepare your 3, 4 & 5-year olds with foundational values and skills they'll use for life.

Our preschool will gently guide your child through structure and lessons built from core values and golden rules. With a curriculum play-based in theory, your child will make sense of the world around them as they are encouraged to develop social and cognitive skills, mature emotionally, and gain the self-confidence required for new experiences and environments.

Built around the core values of Determination, Courage, Respect, Confidence, Playfulness, and Community, our vision is to model and communicate these values while understanding each child's individual needs.

With over 60 collective years of early elementary teaching experience, our philosophy focuses on active involvement, meaningful experimentation, and reinforcement through repetition. Our passion for nurturing children shapes Mrs. O's Six Golden Rules.
