Who We Are
ISA Certified Arborists serving the Portland metro area.
Arboriculture is a technical discipline built on established science, formal standards, and professional credentials. Arbor Ascent is a preservation-focused company that operates on that foundation.
Good tree care doesn't look the same from one tree to the next. Soil conditions, site constraints, structure, health, risk profile — these all shape what the right approach is. We bring the training and diagnostic skill to read those situations accurately and let the assessment drive the work. The outcome is a clear reason behind every recommendation and better care for your trees.
Arbor Ascent was founded by Jackson Chandler, an ISA Board Certified Master Arborist and tree risk assessment qualified arborist with a degree in Environmental Science from Brigham Young University. Each person on our crew is either an ISA Certified Arborist or is in an apprentice position and preparing to earn that certification. We hire to a professional standard and invest in the development of the people doing the work on your property.
A thorough assessment only matters if it leads to real options. We have deep experience in the preservation techniques that keep trees in place — root invigoration, plant growth regulators, root barriers, advanced decay detection, structural support systems. We stay current with the research behind these methods, we understand how they interact in different situations, and we've put in the field time to know what works.
