By the time a tree looks sick, the problem is often advanced, and a wrong diagnosis wastes money. We identify the actual pest or disease and treat it before it spreads to your other trees.
Tree health care built for St. John’s climate
Since lake-effect snow, freeze-thaw cycles, and storms off Lake Michigan stress local trees, and emerald ash borer has killed ash across the region, a generic build won’t hold up here. On the paperwork side, tree work in the public right-of-way in St. John is handled through the town’s public works department; private-property removals usually don’t require a town permit, but we confirm local rules before we start — we manage that for you so you don’t have to.
Serving St. John and the surrounding area
We proudly serve St. John (home to about 21,000 residents) and nearby communities including Schererville and Dyer. We regularly work near Heron Lake and Prairie West Park, and across neighborhoods like Greystone and The Gates of St. John.
