The AEI Difference

The Difference We Bring To Your Part of the World

We’re so much more than a tree, shrub, and lawn care company. The difference we bring to the care of your trees, shrubs, and lawn is a combination of unmatched skill, expertise, and a sincere love for what we do. 

Our trained technicians are specialists in their craft. They receive extensive training to understand the subtleties of tree and shrub varieties and preserve their health. Unlike traditional landscapers, our ISA-certified arborists and trained technicians understand the total growing environment.

Here are just a few more ways we’re different.

Safety Comes First

The moment our certified arborists and trained technicians walk onto your property, they’re focused on the safety of you, your family, your home, and our team. Our Certified Tree Care Safety Professional oversees the training and education of our team. Every project is completed in accordance with the safety standards of the American National Standards Institute and the State of Pennsylvania. 

Accreditations and Certifications That Speak for Themselves

We’re proud to be the first Lancaster County tree care company to earn accreditation by the Tree Care Industry Association. Arborist Enterprises is a member of the Tree Care Industry Association, the International Society of Arboriculture, the Penn-Del Chapter of the ISA, and many other highly-regarded industry organizations.

Our team includes arborists certified by the International Society of Arboriculture, and our President and Co-owner, Ben Tresselt, who is an ISA Board Certified Master Arborist.
