About Us


Trettin Drop In Preschool was established in 1968 by Edith Trettin, who saw a need for quality care in our community. She began her center in donated space at University Congregational Church (now the University Congregational United Church of Christ or UCUCC). No other such model existed and even today there are very few drop-in child care centers, let alone a drop-in preschool. Thousands of families have attended Trettin Drop In Preschool over the last 50+ years. The preschool today is provided with space, financial support and scholarships from the UCUCC, which considers providing quality childcare to be part of their mission to the community. We are governed by the UCUCC Child Care Programs Board of Directors, which also governs the Child Learning and Care Center located on the main floor. Trettin is a secular (non-religious) school.

The philosophy of Trettin Drop In Preschool is to provide opportunities for children to grow intellectually, socially, emotionally and physically in a warm, loving environment. Our play-based curriculum encourages choice-making, autonomy, and social competence. Trettin is a great introduction to group-learning situations for preschoolers. We believe that children learn through play. The exploration of music, science and nature, art and drama, language and numbers is integrated into each day. We want our children to build a positive self-image, explore their natural sense of wonder, discover their creative spirit, learn problem-solving skills, develop self-control and consideration of others, increase coordination, balance, and body image, and know that learning is fun!

Trettin Drop In Preschool does not discriminate on the basis of religion, race, color, sex, sexual orientation, national origin, marital status, veteran status, or physical, mental, or sensory disability. The staff will, to the extent that they are able, make reasonable accommodation to physical and mental limitations of children in care or seeking care. We reserve the right to serve everyone (space available) and do not divide our group by age, except as required by WA State DEL.
