Editorial Review
Our Take on Ross Tree Company
Ross is the plant health care specialist in this ranking, with an emerald ash borer program and arborists licensed through the Colorado Department of Agriculture. The 4.6 rating is the lowest here, though still well above the 4.5 line. It is a better fit for tree preservation than for one-off cheap removals.

Company Background
About Ross Tree Company
Ross Tree Company has been caring for Denver trees since 1978 and operates from 80 S Galapago St. Its approach is different from a removal-first crew. The company starts with plant health care, meaning it diagnoses pests and disease, treats ash trees for emerald ash borer and feeds stressed trees before they decline. Pruning comes next, and removal when a tree cannot be saved. The site says trees are not native to Denver and need extra care in the arid climate, which explains the emphasis.
Credentials are specific. Ross says it has two ISA Certified Arborists who are also qualified supervisors licensed by the Colorado Department of Agriculture, that it belongs to both the Tree Care Industry Association and the International Society of Arboriculture, and that city foresters in Denver and surrounding suburbs list it as a licensed tree contractor. It carries insurance, and it reports an A+ BBB rating.
Reviews back up the plant health focus. One homeowner brought Ross in for a bad beetle infestation, which took several visits, and said the crew was honest about whether the tree was worth saving. Another had a huge overgrown tree trimmed in fall 2025 and photographed it standing intact after a May 2026 spring snowstorm while neighboring trees were damaged. Isiah, Balthazar, Gene and Santiago are all named in reviews for quick estimates and tidy crews.
Ross holds 4.6 from 133 Google reviews, read November 7, 2026, the lowest rating in this ranking, with all five recent reviews we read at five stars. Hours are Monday to Friday, 8 a.m. to 4 p.m.
It suits owners of ash, spruce and other valuable trees who want a long-term care plan. It suits less well someone who only wants a quick, cheap removal. Before booking, ask for a written quote, proof of liability insurance and workers compensation, and the licence number so you can confirm it with the Denver city forester.
