Tree Service Experts

An arborist is a professional in the practice of arboriculture, which is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture. They are also referred to as tree surgeons. 

Our arborists have been certified by the International Society of Arboriculture; Tom Fitzgerald V, #MA-6190A and Tom Fitzgerald IV, #MA-7156A.

Tree Care Professionals in Maryland 

must be licensed by the Department of 

Natural Resources. To obtain this license, the applicant must possess related 

college education plus one year working under another Licensed Tree Expert and then take a certification exam. 

Our Maryland Licensed Tree Experts numbers are 2332 & 2640. 

Potomac River Arborists is covered by  

$2 million of liability insurance as well as Worker's Compensation Insurance. Because of the risks involved with tree work, we recommend customers avoid working with individuals who are not Licensed Tree Experts and who do not have insurance. They maybe less expensive but the homeowner is responsible if the workers are injured or damage property.

Maryland, the District and Virginia are defined by the Potomac River. It is the heart of our region.  Naming the 

company after our favorite river is our 

way of showing our appreciation 

for the river and the people and 

communities that surround it. 

From top to bottom, we enjoy the River: kayaking up north  near Hancock, hiking Great Falls' Billy Goat Trail outside DC and fishing for stripped bass and perch near Point Lookout in Southern Maryland.

The District and Virginia do not have tree work licensing requirements or certifications so beware when a landscape crew or the neighborhood handyman says they'll perform tree work for you. Go with the professionals. Go with us.

The District and areas like Chevy Chase Village and the City of Takoma Park have tree work permit requirements. We will work with you to get the permit through the process.
