About

Mariellen Calabro received her BS and MA degrees in Biology from the College of William and Mary in Virginia. She is a Registered Environmental Manager with the National Registry of Environmental Professionals. 

Mariellen became a Certified Arborist with the International Society of Arboriculture in 2008 and became a Board Certified Master Arborist in 2015.

The ISA Board Certified Master Arborist® credential is the highest level of certification offered by ISA. This credential recognizes ISA Certified Arborists® who have reached the pinnacle of their profession. In addition to passing an extensive scenario-based exam, candidates must abide by a Code of Ethics, which ensures quality of work. Fewer than two percent of all ISA Certified Arborists® currently hold this certification.

In addition, Mariellen is a TRAQ qualified arborist. TRAQ (Tree Risk Assessment Qualification) is an ISA qualification program that trains arborists how to use the methodologies outlined in the ISA Best Management Practices for Tree Risk Assessment. This qualification promotes the safety of people and property by providing a standardized and systematic process for assessing tree risk. The results of a tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity.

She has been the City Forester in DeLand since April 2006.
