About Us


The story of Design Tree Maintenance is really just a simple American Dream Story come true. Robert L. Kett started several years ago, himself, a chainsaw, and a truck. He eventually hired some help while his wife assisted with setting appointments and any necessary clerical work.


A few years down the road, he had a couple crews running and about a dozen employees, and the company had outgrown it’s home, which happened to be Robert’s house. Several years and two offices later, Design Tree Maintenance now has a virtual fleet of trucks, and about 65 employees.


Believing in high ethical standards, and good old fashioned hard work, Mr. Kett built his business into one of the most recognized tree companies in the greater Phoenix area, proudly serving customers for over 13 years. Robert currently resides in north Phoenix with his wife and 4 children, and still goes to work everyday.
