Peak Tree Specialists was built around a simple principle: every project should be overseen by an ISA-certified arborist — not handed off to general labor crews. Our arborists bring deep, regional knowledge of Pacific Northwest species — Douglas fir, western red cedar, bigleaf maple, and the pests and pathogens that target them.

"Peak Tree Specialists have been more than helpful when it comes to removing trees on multiple job sites because we don't have a licensed arborist. We consistently use Peak."

HOAs, property managers, and commercial real estate owners don't need a tree guy — they need a specialist who keeps clear service records, keeps the budget predictable, and oversees every project with an ISA-certified arborist. That's the whole job.
Our commercial programs are built around capital planning cycles and the realities of managing trees across multiple sites in two states.

Documented tree condition and care recommendations, in writing, for every property we service.
12-Month Maintenance Agreements — Twelve Equal Monthly Payments
Predictable monthly budgeting instead of lump-sum billing. Scope, schedule, and cost locked in for the full year.
Multi-Property Management
One contract, one point of contact, one reporting standard across every property in your portfolio — across OR & WA.

Jake, Michael, and their crew did an amazing job cutting down 9 huge trees, and pruning up the remaining 212 trees on the property. This was a big project. Their bid was extremely detailed, fair, and easy to follow. They were very safety conscious and cleaned up the job site every afternoon before they left. Jake and Michael were easy to work with and always available if we had questions or concerns. I would absolutely recommend Peak for all of your tree and landscape projects!

Peak tree specialists have been more than helpful when it comes to removing trees on multiple job sites because we don't have a licensed arborists. We consistently use Peak, as they are very responsive and Mark Pyrah makes sure to get a bid in a timely manner. They do an amazing job when it comes to making sure the grass around the trees still looks good, they pick up all the leaves and debris afterwards and overall are a great company to work with!
