About Timmy's Tree Service
Family-owned arborists serving the Treasure Valley since 2006 — built on science, certified expertise, and a genuine commitment to this community.
Our Story
Modern Arboriculture Made Affordable
Timmy's Tree Service was founded in 2006 by ISA Certified Arborist Timothy Andra and has been locally owned and operated in the Treasure Valley ever since. What started as a commitment to honest, dependable tree care has grown into one of the most trusted arboriculture companies in the Boise area — with offices in Nampa and Boise and over 664 five-star reviews across both locations.
We practice modern arboriculture backed by science. Our team participates in continuing education, stays current with arboriculture research, and uses professional-grade equipment to ensure every tree gets the right treatment — not just the easiest one. That means honest assessments, not upsells.
We are equipped for projects of all sizes. Our ISA-certified arborists are nimble enough for tight residential properties, while our fleet and crew capacity allow us to complete large or complex commercial jobs safely, on time, and on budget.
Boise is known as the City of Trees, and we take that identity seriously. The trees on your property are an investment in beauty, shade, and property value — and we treat them that way.
How We Work
Our Approach to Tree Care
Three things separate us from every other company with a chainsaw and a truck.
Science-Based Arboriculture
We invest in continuing education and stay current with the latest arboriculture research. Every recommendation we make is grounded in science — not guesswork — so your trees get the right treatment at the right time.
Certified Expertise
Our arborists hold ISA Certification (PN-6478A) and TRAQ (Tree Risk Assessment Qualification). We are BBB A+ accredited and actively pursuing ISA Master Arborist certification — the highest credential in the profession.
