ISA Certified Arborist (PN-9239A) · ISA Tree Risk Assessment Qualified (TRAQ)

Tony Petryszyn is an ISA Certified Arborist (PN-9239A) and ISA Tree Risk Assessment Qualified specialist with eight years of professional experience in arboriculture and tree risk management. His background as an Army engineer brings a structural and analytical approach to every assessment — combining engineering principles with deep arboricultural knowledge to deliver objective, credible guidance on tree health, risk, and preservation.

Tony provides independent arborist consulting to estate owners, municipalities, developers, and property managers across the country. His work includes comprehensive tree risk assessments, preservation planning for development projects, tree identification and cataloguing, and expert advisory on managing tree-related liability and asset value. He's built Honorable Tree Service on a straightforward principle: honest, expert analysis — never a sales pitch.

His Army engineering background means he understands structural load, failure modes, and risk quantification in ways most arborists don't. Combined with his ISA credentials and eight years of experience, that gives clients the confidence they're getting analysis backed by both technical rigor and genuine expertise.

A note on the name: Honorable Tree Service reflects Tony's core approach — straightforward, credible, and focused entirely on what's best for the client and the trees.
