About Glenn
Glenn grew up on a tree farm near Northampton in Pennsylvania where his father had owned P. Myster Nursery since the 1950s.  After receiving many requests from customers to diagnose and treat tree problems on their properties which no-one else was able to resolve Glenn decided to start his own business, Myster Tree and Shrub Service, to help customers keep their trees healthy. 

After completing his schooling Glenn founded Myster Tree and Shrub Service in 1986. He is a Master Arborist certified with the International Society of Arboriculture and maintains his certification by participating annually in Continuing Education Programs. 

In addition to his professional accreditation Glenn is a state licensed Commercial Pesticide Applicator and comes recommended by the Penn State Extension Office and the Pennsylvania Department of Agriculture. Myster Tree and Shrub Service is fully certified, licensed and insured and meets the ANSI A300 National Tree Care Standards.
