Tree Wise was planted as a seed back in 1993. This all came during a time where there were only 1400 certified arborists and he felt that the Tri-Valley had a need for a reputable tree service. During that time, Darrell Wise was working as a delivery driver. He was miserable at his job and was ready for a change. He decided to go back to college and finished with a degree in ornamental horticulture. So he was ready and started the business by himself with his fathers old 1972 Chevy pickup.
