TCIA Accreditation is a consumer confidence program administered by the Tree Care Industry Association—America’s oldest and most respected tree care trade association. The TCIA Accreditation program is built on a three-fold foundation: ethics, quality and customer confidence. Accreditation means we adhere to the toughest performance and to the strictest safety standards. It means we are accountable in every way, both locally and nationally.

The national accreditation audit focuses on compliance in the following areas: 1) Safety standards (OSHA), 2) Performance standards (ANSI), 3) Ethical business practices (BBB), 4) DOT compliance, and 5) a drug and alcohol free work place. Docherty Tree Experts is one of only a handful of elite tree care companies to commit to industry safety and performance standards. We’re also the first in the area to operate using professional and ethical business practices as a core element of our business model.
