About

A UA native. Returning home.

The story behind the practice — four generations of roots, an orchard, an old-growth forest, and the streets I grew up on.

The story
David All — Upper Arlington Tree Co.

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.

Rooted in the science

Care that keeps up with the research.

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.
