Your personal arborists

Colonial Tree Service is family-owned and operated by David and Anna Birnschein, both ISA Certified Arborists.  Residents of the Town of Brookfield, they have four children and many pets.  Anna enjoys gardening and reading in her spare time, and David enjoys flying and horseback riding.

During the formative years of Colonial Tree Service, David served the Village of Elm Grove and Town of Brookfield part-time as a firefighter/paramedic.  In 2016, David retired from Fire/EMS to focus exclusively on tree care.  Colonial Tree Service is enrolled in TCIA's national accreditation program to take the business to the next level.
