“It might be a little messy, but it will save your tree.”

No obligation. I'll call or text you back same day.
What your trees need now.
Structural pruning, deadwood removal, and canopy shaping. Hand tools first. We work with the tree's natural form, not against it.
Ask about this →Surgical repair of lawnmower damage, bark tears, and prior improper cuts. Sterile razor work to shape wounds for proper compartmentalization.
Ask about this →Observational diagnosis of pest pressure, fungal issues, structural defects, and decline. Honest evaluation — no upsell.
Ask about this →Early structural pruning prevents costly problems at maturity. The best investment you can make in a tree is when it's young.
Ask about this →Hanging limbs, split leaders, debris on the roof. After a significant storm I reach out to Tree Steward clients first. Walk-ins welcome too — call or text and I'll assess same day when I can.
Ask about this →When a big job needs a crew, or the utility company wants to hack your canopy, you need someone in your corner who speaks the language. I'll walk the job with you, help you evaluate bids, and make sure the work gets spec'd right. Show up the morning of with Tremont Goodie Shop doughnuts for the guys.
Ask about this →The work doesn't disappear into a paper invoice. It becomes a record that grows with the tree.
Open your portal and every tree on your property is numbered and mapped — species, condition, and the photos from each visit. Underneath sits the part most homeowners have never had: my observations, season to season. What I saw in spring. What changed by fall. The cut I made and why. The pest I'm watching before it becomes a problem.
It's the way a doctor keeps a chart, or an orchardist keeps a tree-by-tree log. You stop guessing about your canopy and start knowing it.
A chart per tree
Species, condition, location, and full history — not a whole property lumped into one line.
Photos every visit
Before and after, so you see the work — not just the invoice.
Seasonal observations
What changed since last time, in my words. The quiet problems caught early.
Recommendations
What I'd do next, and why. Act on it or don't — your call, no pressure.
Soil & lab results
When we test, the numbers live here too — pH, texture, what to amend.
Yours to keep
The record belongs to the tree. It stays with your property, even if you sell.
I'm an arborist who also writes software — I built this tool for my own practice. That's why your trees get a record no clipboard or generic field app keeps. Every client I work with gets their own ArbKeep login, free, from the first visit. The Tree Steward program just keeps the chart growing, season after season.
I imagine Upper Arlington as our orchard.
A hundred-tree apple orchard in Pennsylvania was enough to teach me that you can't manage what you don't know. A hundred acres of old-growth forest on the Olympic Peninsula was enough to teach me that the work is never done — only tended. One Tree City of mature canopy is the same covenant, simply more focused.
Most tree problems don't announce themselves. They build quietly — a pest taking hold, a branch losing attachment, a root zone slowly compacting. By the time you notice, the work is bigger than it needed to be.
The Tree Steward program is a standing relationship. I make my orchard round on a regular schedule — checking in on bugs, watching for what's changed season to season. After a storm I reach out before you have to call.
You get someone who knows your trees. I get a route worth driving.
David All · UA '97
I grew up in Upper Arlington — starting on Chester, moving to Henthorn for middle and high school, and finally Ashmore. I traded in the lacrosse stick for the pole saw, but the footwork's the same. My roots here go back generations: my grandparents, the Seegers, raised my father and aunt on Wesleyan and were founding members of UA Lutheran Church.
I returned to Upper Arlington after my father passed away. Walking past Jones and Barrington, I was moved by the ancient Oaks — the living vision of the stewards who built this neighborhood. My career had taken me all over the world. My roots stayed here.
I spent my youth under one of the tallest oak canopies in the city. In middle school, I wrote a poem called 'Tree Heaven' that was published in the UA News. My parents planted trees everywhere we lived in UA; today, those trees are thriving.
What I brought back wasn't just a business plan — it was a practitioner's path. From old-growth forests on the Olympic Peninsula to heritage apple orchards in Pennsylvania, I learned that a tree is a patient, not a project. Antiseptic tools, clean angles, and the nightly walk to see what has changed.
Upper Arlington Tree Co. is an honest way to make a living. I work the streets I grew up on, using a few razor-sharp tools from my grandfather's collection to care for what's been here longer than any of us.
I make my living keeping your trees alive, not cutting them down. Sometimes a big tree genuinely has to go — and when a job truly needs a full crew, I send you to people I trust. A handshake that's been good in this neighborhood for four generations, never a kickback.
Forty years apart

Tools & Practice
Silky saws · Felco pruners · Yoshiaki bonsai shears · Yoshihiro Tsubaki blade oil. Hand-sharpened. Great Grandpa Gammon's pole saw. The Stihl when diameter requires it. Nothing synthetic touches the cut.
Approach
Hand tools first.
Slow work. Done right.
Tree care carries a lot of folk wisdom, and a fair amount of it is wrong. I'd rather follow the evidence. When the Spotted Lanternfly reached Ohio, I went to the Penn State research — out east, where the insect arrived first and the science has had a decade to mature — instead of the operator with the loudest opinion.
I read the journals. I lean on the work coming out of Ohio State and Penn State, the land-grant universities closest to the trees I tend. When a protocol changes — how to treat an invasive, when to make a cut — I change with it.
I've spent time on the academic side, too: I co-authored a peer-reviewed study published in PLOS ONE with researchers at Ohio State. A different subject entirely — but the same habit. Look at the data before you act.

Practice
Evidence first. Hand tools first. Slow work, done right.
The best time to plant a tree was twenty years ago. The second best time is now.
A tree you put in the ground today is a fifty-year decision. Get the species and the spot right and it mostly takes care of itself. Get them wrong and you'll fight it — and lose — for a decade. So I start with the ground, not the nursery tag.
Read the site
Sun and shade through the day, drainage, overhead and underground lines, room for roots, and what's already growing nearby. The tree has to fit the place it'll stand for the rest of your life.
Test the soil
Lab testing when it's worth it. pH and texture decide more than most homeowners realize — the wrong soil quietly starves the right tree.
Match the species
Three recommendations matched to your property — native-first, chosen for the next generation, not just this spring's catalog.
Plant & train it
Set at the right depth, mulched right, and given the early structural pruning that makes the difference between a strong tree and a problem at maturity.
Before the lawns
Native is the floor, not the ceiling. Before Upper Arlington was a suburb — before the streets, before the lawns — this was central Ohio's beech-maple forest, with oak and hickory on the high ground and sycamore and walnut down in the Scioto bottoms. That canopy stood here for centuries before any of us. When I recommend a tree, I'm thinking about what belonged in those woods — and what we can put back.

Not Columbus-wide. Not all directions. UA has a distinct character — mature canopy, a community that genuinely cares about its trees, and a Tree City USA designation since 1990. That focus lets us do better work.
The annexation map tells the story. The oldest neighborhoods — Old Arlington, the original neighborhoods — carry the deepest canopy. Later annexations filled in around them. The trees track the history. Knowing when a neighborhood was built tells you what's growing there and what it needs next.
