Denver Tree Care Since 2003
Four Decades in Tree Care. Tree Pros in Denver Since 2003.
Tree Pros is a family-owned Denver tree care company built around experience, arborist knowledge, honest recommendations, and respect for the properties we work on.
Founder Paul Goin began professional tree care in Golden, Colorado, in 1981.
He became an ISA Certified Arborist in 1988 and spent his career learning the work from the ground up before founding Tree Pros in Denver in 2003.
Today, Tree Pros has three ISA Certified Arborists on staff, every crew leader is an ISA Certified Arborist, and the company is led by Paul as an ISA Board Certified Master Arborist.
We are a small company by choice, focused on doing professional tree care well and building long-term relationships with the people who trust us with their trees.

Built From the Ground Up
Paul Goin Started in Tree Care in 1981
Paul Goin's career in tree care began in Golden, Colorado, in 1981 as a ground laborer.
He did not enter the industry from an office or start by managing crews.
He learned tree care by doing the work.
Over the years, Paul held virtually every role in the profession, including ground laborer, production climber, supervisor, and district manager for some large tree care companies.
That experience gave him a practical understanding of tree work from several perspectives: the tree itself, the people doing the work, the property around it, and the responsibility that comes with making recommendations to a customer.
Paul became an ISA Certified Arborist in 1988.
His career also took him beyond Colorado, with tree care experience in the Netherlands, Suriname, Honduras, and Washington, D.C.
After returning to Denver, Paul started Tree Pros in 2003.
The company was built around a straightforward idea:
Understand the tree first. Give the customer an honest recommendation. Then do the approved work with care.

Practical Experience Matters
From Ground Laborer to Board Certified Master Arborist
Credentials matter, but Paul's experience did not begin with credentials.
It began on the ground.
Working as a ground laborer, production climber, supervisor, and district manager gave him experience with the physical work, tree-care decisions, crew responsibilities, customer expectations, and property concerns involved in professional arboriculture.
That background still shapes how Tree Pros operates.
We do not look at a tree only as a job to prune, remove, or treat.
We look at its condition, structure, species, surroundings, the customer's concerns, and the reasonable options available.
Sometimes the right recommendation is pruning.
Sometimes it is treatment or monitoring.
Sometimes a tree needs to be removed.
Sometimes the best recommendation is to leave it alone.
The service list should not determine the recommendation.
The tree should.

More Than Letters After a Name
Credentials Matter Most When They Improve the Recommendation
Most homeowners do not need a lesson in professional credential abbreviations.
They need to know what is happening with their tree and what they should do next.
Tree Pros uses arboricultural knowledge to evaluate the tree before recommending the work.
That can include looking at tree health, structure, visible defects, storm damage, insects, disease symptoms, growing conditions, previous pruning, surrounding property, and the reason the homeowner called in the first place.
The goal is to turn professional knowledge into a recommendation that makes sense in plain language.
The Tree Comes First
A Recommendation Should Fit the Tree, Not the Service List
Tree Pros does not begin an assessment assuming that a tree needs to be removed, aggressively pruned, fertilized, sprayed, or put into a treatment program.
We begin with the tree.
What condition is it in?
What is happening structurally?
Is it actually unhealthy?
Is there evidence of insect or disease activity?
Did weather cause the problem?
Is the tree creating a reasonable property concern?
Are there practical preservation options?
Does it need work at all?
Those questions matter because different problems can look similar from the ground.
An unhealthy-looking tree may be dealing with disease, insects, drought, roots, soil conditions, previous damage, or several stresses at once.
A damaged tree may still be worth preserving.
A mature tree may need selective pruning rather than removal.
And sometimes removal really is the appropriate recommendation.
Tree Pros' job is to help the customer understand the difference.
Personal Tree Care
Experienced Arborists Without the Big-Company Feel
Tree Pros is a family-owned and operated company.
We want customers to know who they are working with and feel comfortable asking questions about their trees.
Our size allows us to stay focused on tree care, customer relationships, and the quality of the recommendation rather than trying to be everything to everyone.
We work primarily with residential property owners and also provide tree care for commercial properties, HOAs, municipalities, and real estate professionals.
Whether the concern is one declining tree or a larger property with multiple mature trees, the standard is the same:
- 1Listen to the customer.
- 2Evaluate the trees.
- 3Explain the recommendation.
- 4Price the work honestly.
- 5Respect the property.
- 6Do the approved work well.
The Property Matters Too
We Treat Your Property Like It Matters
Professional tree care happens around homes, landscaping, driveways, fences, neighbors, vehicles, and the places people live every day.
That matters to us.
Tree Pros expects crews to respect the property, the residents, and the neighbors around the work.
Cleanup is part of the job.
Our goal is to leave the property in better condition than when we arrived and to provide the highest level of tree care we reasonably can.
That emphasis on property care also appears repeatedly in customer reviews.
Local Experience
Tree Care Shaped by Decades in Colorado
Paul began professional tree care in Golden in 1981, and Tree Pros has served the Denver metro since 2003.
Over that time, we have seen Colorado tree problems change with weather, development, insects, disease, and the aging of the urban forest.
Tree Pros has responded to many heavy snow damage events, the IPS beetle outbreak, the Emerald Ash Borer outbreak, other insect and disease problems, and the tree damage caused by the 2023 Highlands Ranch tornado.
That history provides context when we look at a tree today.
- Heavy spring snow can expose structural weaknesses.
- Wind can break already compromised limbs.
- Dry conditions can add stress.
- Insects and disease can create symptoms that are easy to misread.
- Urban soil conditions and changing landscapes can affect trees in less obvious ways.
Local experience helps us understand that context.
It does not replace evaluating the individual tree.
Tree Pros Since 2003
Here for the Storms, Outbreaks, and Everyday Tree Problems
Some of the most memorable tree care happens after major events.
Much of it does not.
For every severe storm or regional insect outbreak, there are homeowners trying to understand a branch that suddenly died, a tree that looks thinner than last year, a mature tree growing too close to the house, or whether a damaged tree can be saved.
Tree Pros has worked through both.
Our experience with major Denver-area events helps inform our work, but the everyday questions matter just as much.
You should not need a tree emergency to get thoughtful advice from an arborist.

What Customers Say
Tree Care Is About Trust as Much as Trees
Customers invite us onto their property and trust us to make recommendations about trees that may have been part of their home for decades. That responsibility matters.
“They were so professional and respectful. I am a contractor, and I have shared their name with several clients, because they have been so good to work with!”

“I've got a tree with damage that is dying. I contacted Paul at Tree Pros and he gave me quite a lot of advice that I'm hoping will have an impact in saving the tree. I appreciated his detailed advice (it's great when a person can get this kind of info from an expert) and I have my fingers crossed!”
