Damon Schrosk and Andrea Schrosk founded Treecology in 2001 as the nexus of two loves (trees and natural areas) and the realization that it really is all about trees. 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 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.

Blending his knowledge of trees and plants from soil to canopy, Mariano came to Treecology to add a Landscape Division to our growing company. Plants have always been Mariano’s passion. Born and raised in Northern Italy, he has been living in Portland, Oregon since 2004. As a child, he hiked and climbed the Dolomites, and it's the dramatic beauty of these grand mountains, the deep forests and alpine meadows that fueled his passion for plants. After earning a Master Degree in Forestry Science from Padua University, he achieved solid plants expertise working for prestigious wholesale nurseries around the world – Italy, the Netherlands, Germany, New Zealand and the USA. Later he became an ISA Certified Arborist, Certified Landscape Professional, and Organic Land Care Practitioner.
