After much thought and consideration for the safety and well-being of our students due to the ongoing COVID-19 pandemic, we have decided to start our school year using a virtual model. We are confident that by starting the school year in this proactive way, we will be able to develop positive learning routines and establish relationships that will only continue to benefit once it is deemed safe to resume in-person instruction. We look forward to learning and growing with your child this fall, while we patiently wait for in-person instruction to resume.

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 53 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.
