More about Tim Zastrow

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 1930s. 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 Certified Tree Risk Assessor, a Certified Tree Safety Professional, and a member of the American Society of Consulting Arborists. Tim gets great pleasure every day helping people enjoy and care for their trees.

What Our Customers Are Saying About Tim Zastrow

We have two very large 100-year old sycamore trees behind our house, both with deadwood which had started to break off and fall on our patio area. We were concerned that this was a dangerous situation, so we contacted several tree companies in the area to get estimates. Tim Zastrow, the arborist sent by Bartlett Tree Experts, did a really nice job explaining to us the type of maintenance sycamores need, we were confident that the solution he proposed was the right one. He also recommended putting in a lightning protection system in both sycamores, which we thought was a pretty good idea.

Bartlett's wasn't the least expensive of the companies we contacted, but it also wasn't the most expensive (by far). Tim offered a discount if we wanted to wait until November to get the work done, but since the deadwood was falling now, we decided to go ahead and schedule the work. The team that came out was excellent -- they arrived exactly when they said they would and did exactly what we contracted them to do. The tree climbers are highly skilled. We were worried that falling branches might hit our new metal roof, but the climbers were careful. They did a great job, and our new lightning protection system will be a conversation piece for sure. The job took most of the day, and Tim came out to check on the work himself. It was an all-around nice experience.

We have a dying pine tree that needs to be removed and we will schedule this work with Bartlett's in November to get their winter discount. We are really happy with the work they did for us, and we will be repeat customers for sure. Shawn T., Chevy Chase, MD

Tim is, of course the tree guru of Montgomery County, and he was exceptionally helpful as we decided the future of a sycamore on our property -- actually two sycamores. He was also patient as he taught me about how a tree feeds sustains itself and grows -- and where to look for the weak spots and the signs of decay/trouble. We decided to have one large sycamore trimmed and re-cabled. His crew was prompt, professional, skilled, and considerate of us and the neighbors. They left the work site spotless, and left everyone involved happy. Debra R., Bethesda, MD

I cannot pay enough in praise of their professionalism and personal efforts. Their relationship with each other was seamless. Each knew what he had to do, alone or with the others, without "to do", did it. What's more after all of the cutting, sawing, chipping, stacking, etc., they cleaned up my garden, front and back, and finished by sweeping the area in front of the house…I'm still impressed. June S., Chevy Chase, MD
