OUR APPROACH TO TREE CARE
Applying modern arboriculture through objective-based tree care
OUR STORY
Northern Boston Tree Service® was formed when a small group of arborists came together with a shared philosophy about how trees should be cared for. From the beginning, our goal was to practice tree care with preservation as the default.
Each of us had spent years working in the tree care industry and witnessed firsthand how short-term, production-driven practices can undermine the urban forest. As many tree companies grow and scale, the work can become increasingly transactional, shaped by speed, efficiency, and production. In that environment, recommendations can drift toward what is easiest to schedule, fastest to execute, or most profitable, rather than what best supports long-term tree health, tree structure, and canopy retention.
We believed there was a better approach, one rooted in modern arboricultural science, ecological responsibility, and a deep respect for trees as living organisms. Our vision was simple and clear: to raise the standard of tree care in our community by placing tree preservation and long-term outcomes at the center of our work. From the beginning, Northern Boston Tree Service® was built around the belief that responsible tree care should be purposeful, conservative, and tied to defined objectives that improve tree structure and protect the urban canopy.
That vision continues to guide everything we do today. Our work reflects a long-term commitment to protecting the urban forest so that future generations can experience the environmental, social, and ecological benefits that mature trees provide.
OUR PRINCIPLES
Northern Boston Tree Service® is a tree preservation company first, and a tree service company second.
We understand trees as living organisms whose structure can adapt to stress when managed properly. In practice, this means taking the time to understand how an individual tree responds to load, injury, and changing site conditions. A tree’s structure develops over time in response to environmental forces and past management decisions.
For this reason, our work begins with careful evaluation of the tree and a clear definition of the objective we are trying to achieve. Pruning and risk reduction are applied deliberately and in accordance with professional standards, with each intervention serving a specific purpose. The goal is to improve branch structure in ways that reduce the likelihood of failure and support long-term tree preservation.
We believe ecological responsibility is not a marketing phrase. It is a series of deliberate decisions made on every property. This includes minimizing unnecessary removals, prioritizing preservation whenever feasible, and making recommendations that support the best long-term outcome for the tree above all else.
We also believe tree preservation includes knowing when to do less. Mature trees provide ecological benefits that cannot be easily replaced, and thoughtful tree care management often means reducing risk while retaining as much of that living system as possible. When a tree truly cannot be preserved, we aim to remove it with precision and minimal site disturbance, and we help clients plan the next generation of canopy.
OUR PROCESS
We approach tree care as long-term stewardship, not a one-time transaction. We understand trees as living organisms whose structure can adapt to stress when managed properly. In practice, this means taking the time to understand how an individual tree responds to load, injury, and changing site conditions. A tree’s structure develops over time in response to environmental forces and past management decisions. Our process starts with understanding the tree and the site before making recommendations. We evaluate structure, load distribution, growth patterns, defects, targets, and the underlying site conditions that influence stability and vitality.
We believe effective tree care is also a collaborative process. By listening carefully and asking questions, we work with our clients to understand their concerns and priorities. This allows us to develop a customized tree care plan for each property, addressing specific branches or issues while also improving overall tree structure and long-term safety.
Our pruning work is preservation-forward and standards-based. We prioritize structural pruning and weight management to reduce the likelihood of failure while retaining as much functional canopy as possible, rather than relying on aggressive thinning or unnecessary reduction. This reflects how structural pruning is described in professional literature and aligns with the idea that pruning should be purposeful, conservative, and tied to specific objectives.
Throughout the project, we maintain clear communication and a well-defined scope of work so clients understand what we are doing and why. Our goal is not simply to complete a job, but to deliver a professional-quality work product that results in safer trees and long-term benefit for both the property and the urban forest.

Zachary is a Massachusetts Certified Arborist (MCA), ISA Certified Arborist, ISA Certified Urban Forest Professional (ISA Municipal Specialist), TCIA Certified Treecare Safety Professional (CTSP), and holds both the ISA Tree Risk Assessment Qualification (TRAQ) and the Florida Chapter ISA Prescription Pruning Qualification (PPQ). He is a graduate of the University of Massachusetts Amherst and has been involved in the green industry for many years. In 2012 he returned to the tree care community in the Boston area where he met a group of local arborists and soon after formed Northern Boston Tree Service® Inc. to provide an environmentally responsible approach to tree care through urban tree preservation.
TREE CARE AS STEWARDSHIP
Tree care should begin with the tree. That may sound obvious, but in practice, it is not always how the industry works.
Much of the modern tree care industry today is organized around production: large crews, expensive equipment, high volume, and the need to keep schedules full. There is nothing inherently wrong with efficiency, equipment, or scale. All have an important place in arboriculture. But when a business is built around constant output, its operational needs can begin to influence the recommendations made for the tree.
Over time, the needs of the business itself can begin to shape the recommendations made for the tree.
The result is an industry in which homeowners are so often offered the same narrow range of solutions: thin it out, clean it up, or cut it down. These recommendations are familiar, easy to define, and well suited to production. But proper tree care is not based on applying the same broad treatment to every tree. Arboricultural best management practices call for an objectives-driven approach: first understand the tree, identify the specific conditions of concern, define what the work is intended to accomplish, and only then determine whether pruning or another intervention is appropriate.
We have seen how the production model can lead to excessive pruning or unnecessary removals being labeled as “tree care.” The irony is that, in the name of tree maintenance or risk reduction, trees are sometimes subjected to more stress and long-term damage than they would have experienced if left alone.
Northern Boston Tree Service® was built around a different idea. We have intentionally remained a small, specialized team rather than growing into a large, production-driven operation because we believe careful tree care depends on careful evaluation. Working at a smaller scale gives us the freedom to evaluate each tree individually and recommend what we believe will serve it best.
Our approach is based on restraint as much as action. We begin with evaluation, not a preset scope. We seek to understand the tree, identify the specific conditions of concern, and define clear objectives. Only then do we determine whether work is warranted and choose the simplest approach that can achieve the goal.
Sometimes that means a limited, highly targeted intervention. Sometimes it means improving structure while preserving the canopy that the tree needs to function. And sometimes the best decision is to leave the tree alone.
When pruning is appropriate, we follow a standards-driven, objectives-based approach. The work should have a reason, a method, and an intended outcome. The goal is not to remove a predetermined amount of canopy or create the appearance that substantial work has been done. It is to accomplish what is necessary while preserving as much of the tree as possible.
Equipment has its place, but it is not a measure of professionalism. We do not measure the quality of tree care by the size of the operation, the amount of debris removed, or how dramatically different a tree looks when the work is finished.
We believe the measure of good tree care is whether the right decisions were made and whether the tree is better off as a result of the work that was done.
Our responsibility as stewards of the urban forest is to make the best decisions we can for the tree in front of us and to leave it better prepared for the years ahead.
Northern Boston Tree Service® was built on a simple principle: tree care should begin with the tree and it should remain at the center of every decision that follows.
