Tree Care Is an Art Form. We Treat It That Way.

Tree Zen was born from a simple belief: Colorado's trees deserve certified expertise, not just anyone with a chainsaw.

Built by Cory Simmons.
Trusted Across Colorado.

Tree Zen LLC was founded by Cory Simmons — a Westminster, Colorado tree care professional who built his company on a simple belief: every customer deserves competitive pricing, high quality work, and a crew that shows up when they say they will.

Since 2003, Cory and his team have completed 4,000+ jobs across the Front Range — from routine trimming to storm damage cleanup, fire mitigation, land clearing, and full exterior construction projects. No job is too big or small.

Cory's crew covers the entire 200-mile I-25 corridor from Fort Collins to Pueblo. One company, one call — for everything your trees and property need.
