About Treecology, Inc.

Based in Milwaukie, Oregon, we serve the Portland, Oregon Metro Area and the urban/rural interface beyond. Treecology has memberships in the International Association of Arboriculture, Tree Care Industry Association, Society for Ecological Restoration, Hoyt Arboretum, Arbor Day Foundation and Portland Japanese Garden Society.

Damon Schrosk

Damon Schrosk

ISA Certified Arborist PN5474A
Certified Tree Risk Assessor PN-171
Certified Tree Safety Professional 00258

Damon Schrosk graduated from the University of California in San Diego in 1994 with a degree in Ecology, Behavior and Evolution and a minor in Photography. After a career in wildlife and habitat biology that took him from the desert southwest to the North Slope of Alaska, he became a wetland delineator and worked as a consultant, delineating, designing mitigation projects and monitoring projects. The monitoring of the projects identified a need in the installation and maintenance of them, one that came from years of education and experience in working in and with natural plant communities. This was combined with a resurgence in the desire of caring for trees that stemmed back from his youth working with his dad on bonsai and walks through the woods with his grandfather.
