About Us

At Tiny Trees Preschool we play to learn

We help kids enter kindergarten ready to thrive.

We help children learn to read, succeed at math and explore the wild where they receive both a world class science education and a gleefully muddy childhood: one full of play, exploration and wonder in the great outdoors.

The best part is we offer this joyful education at a price you can afford: 10-40% below the average Seattle preschool.


Our mission is to use outdoor classrooms to make a quality education in reading, math and science affordable for families and to give children a joyful, nature rich childhood – one full of play, exploration and wonder.

Our vision is to create a community where all children have access to high quality education and develop the social, emotional and academic skills needed to thrive in school and life.


As we grow, stumble, innovate and change these are the constants that guide our work.


We believe in a middle path to preschool education where children receive both the reading, math and science necessary to succeed in kindergarten, the social and emotional skills to thrive in school, and the vibrant, nature rich childhood they deserve.

We are influenced by the work on executive functions (aka emotional and social skills) by Dr. Adele Diamond at the University of British Columbia (see her TED Talk here)  and by the frontiers of innovation initiative at Harvard’s Center on the Developing Child. We are inspired by research at the Institute for Learning and Brain Science (I-LABS) at the University of Washington which demonstrates that children learn best from people (not screens) and that the quality of your teachers = the quality of your learning. Lastly, we are rooted in the publicly funded forest kindergarten models that have been so successful in Scandinavia and northern Europe (countries that lead the world in educational outcomes). Schools like this one in England or this preschool north of the arctic circle in Norway.


Kindergarten Readiness: Prepare children to thrive academically.

Emotional & Social Development: Help children develop essential executive functions like impulse control, communication and empathy.

A Vibrant, Nature Rich Childhood: One full of play, adventure and wonder.

To meet our goals we will use a celebrated, evidence based curriculum called High Scope. We chose it because:
1) It has a strong evidence base (they ran the first study on preschool learning 50 yrs ago – the perry preschool project).
2) The City of Seattle recommends it as a standard of quality for their preschool program.
3) It works outdoors. The model is dependent on the quality of the interaction between the teacher and student not expensive props, prepared worksheets or ipads.

We aim to measure our quality through the Early Achievers system developed by the University of Washington and used by Seattle’s new Preschool Program (prop 1b). This allows us to measure the quality of each school in a transparent way that is public record for parents.

Our teachers will be tracking student progress using teaching strategies gold. This helps them make sure they are meeting the individual need of every student no matter where they are in their learning progression.

Tiny Trees Preschool is also a provider for the Seattle Preschool Program – Pathways. This means if you don’t make a lot of money you may qualify for FREE tuition paid for by the City of Seattle. Learn more here.
