Dont Waste Your Weekends Working in the Yard Allied Tree Service is a locally owned and operated business in Tyler, Texas since 1990. Nothing makes your property look better than gorgeous, healthy trees. Think of the big oak in your yard as a natural art piece that draws people in. However, no matter how beautiful the tree on your property looks, it can still pose a danger if it's not maintained properly. Dead and dying trees can fall over at any moment or drop branches on cars, roofs, pets and people. Call Us Today!
