American Tree Experts was founded in 1950 by Chester Ziemienski, who had a passion for providing care to the trees that surround our neighborhoods. After graduating with a degree in forestry, Chester saw a need for a professional tree care provider and City Tree Service was founded. Later renamed to American Tree Experts, the business was sold 30 years later to Chester's oldest son, Jesse Ziemienski, who is the current President of American Tree Experts. Jesse's son, Dean Ziemienski, joined the company in 2007 and has since become Vice President.

Planting the right tree in the right place not only enhances your property, but also helps to ward off problems later.

Many trees are susceptible to a variety of regional diseases and insect infestations, which often require a tree health specialist like those on our staff to make a diagnosis. See our certified arborists who can identify common insect and disease problems. We can offer preventive, long-term measures to help protect your trees. Many favorite trees suffer from small wood-boring insects that bore into the trees in search of food and shelter, inhibiting the tree's ability to transport food and nutrients.

Sometimes pruning isn't enough to solve serious problems, and your only option may be to have your tree removed. The professionals at American Tree Experts are trained to recognize and correct these safety hazards with removal services. Tree and stump removal tends to be hazardous work. Safety is our highest priority, with minimizing invasiveness to your landscape not far behind. Leave it to our experts to take care of your tree removal without ruining your property or your budget. We have the skills and the specialty equipment to manage all facets of the removal, from assessing the actual health of your tree and setting up the rigging systems to grinding the stump into mulch before we leave your property.

We prune young trees to establish good structure and to mimic what would occur naturally in a forest, enabling your young trees to mature into strong, resilient trees. Moreover, trees pruned while young tend to require less pruning as they age. Pruning of mature trees can reduce safety hazards by removing deadwood and weak limbs, which could fall to the ground. Removal of dead branches also helps to prevent decay from spreading in a tree. Pruning is also performed to remove diseased or insect-infested branches from trees and shrubs.
