ISA Certified Arborist Services in Edmonds, WA
As an ISA Certified Consulting Arborist with Tree Risk Assessment Qualification (TRAQ) and ASCA registration, I provide expert tree care solutions rooted in over a decade of specialized experience. My practice focuses on unbiased tree health evaluations, aerial inspections through non-invasive climbing, and precise risk assessments that prioritize both safety and tree longevity. Clients benefit from my independence as a consulting arborist unaffiliated with tree service companies, ensuring recommendations remain free from commercial influence. I offer comprehensive services including pre-construction planning, species selection for mitigation planting, and municipal code compliance guidance across King and Snohomish Counties. My technical expertise extends to diagnosing insect infestations, writing detailed reports for permitting purposes, and conducting thorough aerial inspections using climbing techniques when ground-level assessments prove insufficient.

With deep familiarity in local critical area ordinances and shoreline regulations, I help property owners navigate complex environmental requirements while maintaining tree health. The recent expansion of services to HOA greenspace optimization reflects my commitment to adapting arboricultural expertise to evolving community needs. My practice maintains strict adherence to ethical standards through continuous education in emerging tree care science, ensuring clients receive current, evidence-based recommendations that balance property safety with ecological stewardship.
