The school will continue to be located in Redmond, WA on our 12 acre forest campus.

After 20 years Ann Glaser is handing over the reins to Sanna Luoma - the director of the new Sisu Outdoor School.

The new school will continue the amazing teaching, play and learning that thousands of students have experienced with Tiny Treks NW over the past 20 years. Add to that the power of “Sisu”, the foundation for Finnish Forest schools and your children will experience an outdoor school that will last a lifetime.

Meet Sanna Luoma

Ann Glaser has been running Tiny Treks NW for over 20 years. Teaching over 1000 students at Tiny Treks NW, Ann Glaser is excited to wind down Tiny Treks NW while Teacher Sanna powers up Sisu Outdoor School. Teacher Sanna is thrilled to transition from leading the Tiny Treks team to establishing Sisu Outdoor School to carry on the world class outdoor education programs. Sanna (she/her) was born and raised in Finland where she developed a deep connection with the natural world at very early age. Sanna has a bachelor’s degree in early childhood education with a focus on outdoor education from the University of Helsinki in Finland, and she has completed Skogsmulle training, the Scandinavian early years outdoor training program. Sanna relocated to Seattle area in 2016 with her family and has taught in preschools in Seattle, Bellevue and Snoqualmie. Sanna believes children are competent and capable from early on and sees herself more as a facilitator and a co learner alongside the children.

In her free time Sanna loves to adventure the beautiful Pacific Northwest with her furry sidekick, a Border Collie named Mr H. Sanna lives in Issaquah with her husband and two teenage children
