Tree preservation is our ultimate goal.

Our tree preservation experience spans across the country and has been recognized nationally for excellence in arboriculture.


Structure in trees is like the foundation is to a house- you must have a sound foundation for long-term success.

Fertilization and Soil Management

We have many tools to improve tree health, but few work as quickly and decidedly as our custom blended Liquid Fertilizer Injection.

Planting and Transplanting

We hand select the best trees from the finest nurseries for our clients. Structure and aesthetics are the primary factors when selecting your trees.

Tree & Stump Removal

Although we focus on tree preservation, tree removal is a necessary service when they pose a danger.

Cabling and Bracing

Most urban trees have some sort of structural defect. When these defects reach a critical point, it can cause extensive property damage or a total loss of the tree.

Insect and Disease Management

Our focus is on not just the obvious problems but on improving tree health along with sensible pest management.

Structural Remediation

This service pertains to our passion for old trees of notable or historical provenance. We custom design systems to keep the trees from structural failure.

Tree Evaluation & Witness Services

William de Vos, RCA #359, is Vermont’s only Registered Consulting Arborist; a certification requiring the highest professional standards for practical arboriculture.

Site Assessment, Protocol Development and Project Management

A specific step-by-step set of protocols and a long-term maintenance plan are a must for success.

Lightning Protection and Testing

We have extensive experience in lightning protection installation for trees. Our systems exceed the current ANSI A300 standards for trees and meet UL Approval.

Custom Care Programs

We enjoy a challenge most of all and will create a program for any condition, no matter how far out from traditional methods it may lie.
