David is passionate about helping other arborists and is generous in sharing the lessons he’s learned in running and marketing a tree service.

In addition to ArborScape’s in-house apprentice program,  David Merriman devotes his time to working with at risk youth. He hopes that by sharing a trade, that has brought him so much, young people will have a better chance of contributing to their communities.

In 2008 Merriman helped start a new program with the Jefferson County Work Force Center, to train arborists. It consists of 13 weeks of classroom instruction combined with on-the-job training. Then the students are placed with a private or public sector employer where they spend 3 hours in the classroom, and 16-24 hours in the field.

During his free time he enjoys ATV-ing, spending time with family and reading.
