Premier Tree Services in Williston, VT
Locally Owned, ISA Certified Arborists Focused on What’s Best for Your Landscape
Trusted Local Arborists Who Know Your Trees
Williston is changing — its neighborhoods, its streetscapes, and its tree canopy. Maturing landscape trees are outgrowing where they were planted, emerald ash borer is reshaping what's left standing, and new development is reshaping the rest. Good tree care here means knowing what's worth saving, what's worth replacing, and how to tell the difference. Teachers Tree Service has been making those calls alongside Williston homeowners since 2003.
Our Tree Services in Williston
We provide a full range of tree care services across Williston — for homeowners with a single tree concern and for property owners managing acres of mature canopy.
Tree Pruning & Trimming
We prune to keep your trees healthy, strong, and the right shape for your property — clearing deadwood, opening up views, and shaping young trees so they grow up well.
Tree Removal
When a tree is dead, dying, or in the wrong spot, we take it down safely — even in tight quarters or near power lines. We use the right equipment for the job, from climbers to bucket trucks and crane support.
Emergency Tree Service
When a storm puts a tree on your house or blocks your driveway, we respond around the clock and prioritize the most critical situations first.
Insect & Disease Treatment
From emerald ash borer to spongy moth, the threats to your trees can do real damage in a single season. We diagnose accurately and treat only when treatment is actually warranted.
Fertilization
Trees in lawns, near pavement, or in poor soils often run short on nutrients. We deliver fertilizer directly to the root zone with the right formulation for your tree.
Tree Preservation
For valuable trees in trouble, we use structural support hardware, root collar inspections, and growth regulators to give them the best shot at recovery.
Tree Planting
We help you pick the right tree for the right spot, then plant it the way it should be planted — proper depth, proper mulch, and set up to thrive.
Soil & Root Zone Management
Compacted soil and damaged root zones are common reasons trees fail. We use air spading to break up packed soil and add the amendments your tree's roots need.
Habitat Enhancement
Trees, snags, and woody debris all play roles in supporting birds, pollinators, and other wildlife. We work with property owners to keep these features in place — and add them where they're missing.
Woodlot Management
For property owners with acres of trees, we build long-term management plans that balance tree health, wildlife habitat, views, and how you use the land.
What We Love Most About Williston
Williston is one of the most interesting towns in our service area — a place actively negotiating its own future. With a steady population just over 10,000, the town combines historic farmland, a walkable village, industrial parks, and the shopping district off I-89, all within a 20-minute commute of Burlington. Williston's form-based development code, adopted in 2022, prioritizes walkability, mixed-use neighborhoods, and the green spaces that make a town livable — and trees are central to that future.
When we're off the clock, our team enjoys some of the same Williston spots our clients do:
Catamount Outdoor Family Center: A four-season outdoor center on the old Catamount family farm, with miles of trails for mountain biking, trail running, and Nordic skiing.
Isham Family Farm: A working family farm offering pick-your-own berries, sunflower fields, hayrides, and seasonal events in a classic Williston barn setting.
Adams Farm Market: A farmstand and country store stocked with local produce, Vermont meats, baked goods, and the kind of staples you can't get at a big box store.
Paquette Full of Posies: An independent Vermont nursery and garden center — a great source for trees, shrubs, and perennials suited to local growing conditions.
Gardener's Supply Co: The Williston flagship of the Vermont-based garden retailer, where our team often picks up plants and tools for our own yards.
Guy's Farm & Yard: A Vermont-grown garden and feed store with a deep selection of plants, tools, soil, and outdoor supplies for homeowners and growers alike.
Village Hardware: A locally owned hardware store in the heart of Williston Village, stocked with everything from fasteners and tools to lawn and garden supplies.
Dorothy Alling Memorial Library: Williston's town library, a community hub offering programs, events, and resources for residents of all ages.
Williston Recreation & Parks: The town's parks, recreation paths, and community programs —covering everything from youth sports to adult fitness classes and the seasonal events that bring residents together.

Williston Tree Care Tips & Local Insights
Caring for trees in Williston comes with a few local realities worth knowing about:
Emerald Ash Borer Is Here: EAB was confirmed in Williston in August 2022, and untreated ash trees die within 3-5 years. Healthy ash can be saved with trunk injection treatment, but the window closes once a tree starts to decline.
Older Neighborhoods Often Have Trees in Trouble: Many homes built in the ‘70s and '80s have trees planted too close to foundations or buried too deep — issues that show up decades later as decline, leaning, or root failure. If your neighborhood is from that era, your trees are worth a closer look.
Williston Has No Tree Ordinance: Tree decisions on private property are largely your own, and there's no local body confirming a contractor is qualified or insured. Always confirm any tree contractor carries general liability and workers' compensation insurance and employs ISA Certified Arborists.
Trees Near Power Lines Need a Qualified Line-Clearance Arborist: Green Mountain Power handles vegetation management for primary lines in Williston, but secondary service drops to your house — and any tree work near energized lines — require a qualified line-clearance crew.
Vermont Law Requires Utility Marking Before Any Digging: DigSafe covers stump grinding, tree planting, and any other excavation. Call 811 at least 72 hours before work begins.

What Teachers Tree Service Brings to Williston
Williston has plenty of options for tree work. Here's why your neighbors choose us:
Locally Owned and Operated Since 2003: Greg Ranallo founded the company and still walks properties with clients today.
8 ISA Certified Arborists on Staff: Every recommendation is backed by formal arboricultural training, not guesswork.
TCIA-Accredited: A credential held by fewer than 5% of tree care companies nationwide — verifying our safety, business practices, and consumer protections.
Trained in Tree Biology, Not Just Tree Work: Our team includes arborists with backgrounds in forest ecology, ecological restoration, and plant pathology — depth that shows up in better diagnoses and longer-lasting outcomes.
A Full-Service Team, Not a Removal Crew with Extras: Many tree companies do removals well and everything else as an afterthought. We're built for the long arc — pruning, plant health care, planting, and preservation — so your trees have someone in their corner no matter their condition.
Honest Recommendations: We won't push treatment on a tree that isn't worth saving or recommend removal on a tree that can be protected. You'll get the call we'd make on our own property.
20+ Years of Williston Relationships: Some clients have been with us since the company started — that’s trust built over time, not something you can manufacture overnight.
