About our Company

Mission: The Tree Consultants advocates for conservation and stewardship of trees.


We serve this purpose through the practice of arboricultural consulting. 

For more than 20 years Joe Mangan was president of Dallas Tree Specialists. The company provided commercial and residential tree care services  in the Dallas - Ft. Worth metroplex.

In 1992 the International Society of Arboriculture introduced certification. Mr Mangan had the distinction of being one of the first 17 Certified Arborist in the state of Texas

The American Society of Consulting Arborist (ASCA)

sponsors a Consulting Academy. A systems approach to all of the elements of a consulting assignment were taught.  


Attending and graduating from the Consulting Academy was a  noteworthy achievement  in Mr Mangan's career as a consulting arborist.

Mr. Mangan holds a Bachelor of Science in Business Administration from the University of Texas at Dallas.
