Tiny Trees Preschool

Marker Seattle, United States
Tiny Trees Preschool gives children a quality education and a joyful, nature rich childhood. By creating vibrant, outdoor classrooms in Seattle, King County parks, Tiny Trees eliminates the cost of a brick and mortar facility and invests in what really matters: empowering great teachers.

From Acorns to Oaks

“Tiny Trees gives children a vibrant, mud puddle splashing, sand castle building, & creepy crawly catching childhood.”

Adana Protonentis, Executive Director

In October of 2014 Tiny Trees Preschool won Social Venture Partners’ Fast Pitch competition for best non-profit start up. At the time, the dream of affordable, nature rich, outdoor preschool was just that – a dream. It became a reality in September 2016, when Tiny Trees opened preschools in four city parks in low income neighborhoods across Seattle, followed by 3 more schools in September, 2017. Now every day, in all weather, more than 300 children attend joyfully muddy classes, learning the social, emotional, and academic skills for a lifetime of success while enjoying a glorious childhood: one full of play, adventure, and wonder in the natural world.

Tiny Trees gives children a vibrant, mud puddle splashing, sand castle building, & creepy crawly catching childhood: one full of hands-on learning, exploration, and wonder in the natural world. Our children have inherited a planet facing significant ecological challenges and their generation will need capable, emotionally intelligent, and creative conservation leaders. Tiny Trees Preschool presents a solution – daily, intimate exploration of the natural world by children from diverse backgrounds during their most formative years.
