Mr. Tim Zastrow
Bartlett Tree Experts
Growing up in suburban Maryland, Tim first learned to appreciate trees and the world around him from his maternal grandfather who was an avid gardener and amateur naturalist in Syracuse, New York. When Tim was seven, his grandfather gave the family a Butternut seedling from a tree that he had started from a seedling in the 1930’s. The young tree was planted with love and lots of compost on his family’s property in Colesville, Maryland. Tim then watched it grow to maturity. While pursing a degree in Entomology at the University of Maryland, he started working in the field of arboriculture in 1985 for TreeMasters. In 2001 Bartlett acquired this company and Tim got the chance to combine his skill and experience with Bartlett’s advanced technical resources and robust safety and training programs. He is a Board Certified Master Arborist, a Maryland Licensed Tree Expert, a Qualified Tree Risk Assessor, a Certified Tree Safety Professional, and a registered Consulting Arborist. Tim gets great pleasure every day helping organizations maximize tree benefits while minimizing tree risks.
