Biological Tree Services continues to spread its roots

Biological Tree Services, LLC (BTS) recently added two employees to its Green Team. David Patterson joined the company as field operations manager, and Frank Hammer joined BTS as a certified arborist.


Patterson brings more than 25 years of construction, restoration and maintenance experience from working at top ranked private golf clubs and landscapes in the state of Florida. At BTS he will provide professional support and service for turf and landscapes. His background specializes in identifying nutrient deficiencies in all types of turf grasses, and detecting insect damage and recognizing harmful diseases within plant beds, turf, palms and trees.


Hammer has worked in the Green Industry for 15 years and has maintained his International Society of Arboriculture certification since 2006. Working with Biological Tree Services Hammer will specialize in getting to the “root of the problem” for your trees. His focus will be working with the air knife, an arborist’s tool which allows full excavation of a tree’s roots without risking damage to the tree or buried utilities. In conjunction with this tool he will perform deep root soil injections, vertimulching, and other services that will contribute to the health and well being of your trees.
