More about Tim Zastrow

Growing up in suburban Maryland, Tim first learned to appreciate trees and the world around him from his maternal grandfather. When Tim was seven, he gave Tim’s family a Butternut seedling from a tree that he had started from a seedling in the 1930s. Tim loved watching the tree grow to maturity. In 1985, while earning his degree in Entomology at the University of Maryland, Tim started in arboriculture working for TreeMasters. He joined Bartlett Tree Experts as an Arborist Representative in 2001, when Bartlett acquired that company. Tim welcomed the chance to combine his skill and experience with Bartlett's advanced technical resources and robust safety and training programs. Since that time, he has held positions in residential sales, full-time commercial sales, and served as Assistant Local Manager in the DC Market. Tim now leads our Frederick, Maryland office and serves a mix of residential tree owners and commercial tree managers.

A Registered Consulting Arborist and an ISA Board-Certified Master Arborist, Tim is also a Maryland Licensed Tree Expert, a Certified Tree Risk Assessor, and a member of the American Society of Consulting Arborists. Tim gets great pleasure every day helping people enjoy and care for their trees and shrubs.

In his free time, Tim loves to hike, enjoys birding & gardening, and takes particular delight in working with wood and metal in his home shop.

We may be a contractors nightmare having changed our minds a time or two in the middle of the operation. We have the champion Osage Orange for Frederick County, so you may understand it is huge and a treasure. We love the old tree for many other reasons. When it began dropping limbs we decided to take it down, a process that requires a different approach than preservation. Midway of cutting off the limbs we could not stand killing it so asked instead how we might keep it. That required judicious bracing and limb removal and the radical mental change of intention from the crew. They did a terrific job, the closer trimmed area is sprouting new growth and the tree seems vigorous. But, there was one great long limb over the house that was making me uneasy. They have successfully, really one could call it artfully, trimmed that limb back while preserving a graceful appearance. Their work was outstanding. Safely done with expert guidance from their horticulturist. Many thanks.
