What We Do

Services built for serious properties.

Every project is approached with the same standard — clean execution, considered design, and craftsmanship that holds up over time.

01
Landscape Design
Custom design plans tailored to your property, climate, and vision. We design landscapes that look intentional — because they are.
02
Installation
Sod, planting, mulch, garden beds, retaining walls, gravel, and boulders. Full installation from design to finished grade.
03
Tree Trimming
Precision canopy work that keeps trees healthy, balanced, and safe. We understand Colorado's trees and how to care for them properly.
04
Tree Removal
Safe, efficient removal of hazardous or unwanted trees. Clean work, complete haul away, property protected throughout.
05
Rock & Boulder Work
Large-scale rock placement, gravel installation, and decorative stone. We source and transport materials — no coordinating on your end.
06
Seasonal Cleanup
Spring and fall cleanup to keep your property clean and ready. Debris removal, bed prep, and ground maintenance done right.

Richie Hadley, owner of High Ground Theory
About

The work speaks. The results stay.

Richie Hadley has been doing landscape and tree work since 2019 — working across Colorado, learning the craft from the ground up, and building a reputation for showing up and doing it right. High Ground Theory is his first business, and it's built on everything he's learned along the way.

Richie brings personal touches to every project. Landscaping isn't just a job to him — it's a passion. He genuinely enjoys helping people transform their properties, and that care shows in the finished work. When you hire High Ground Theory, you get someone who's easy to work with, shows up on time, runs a solid crew, and leaves your property cleaner than he found it.

Trustworthy. Reliable. Built on relationships.
