A Common-Sense Approach

With an understanding of how a tree fits into your long-term plans,

Merriman creates your customized trimming or PHC plan.


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

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.

Merriman takes a common-sense approach to helping ArborScape’s clients. Understanding how a tree fits in their long-term plans guides his approach to creating a trimming or PHC plan. He manages some of ArborScape’s largest commercial tree service clients including; NREL, Army Corps of Engineers and the City of Aurora.
During his free time David enjoys the ATVing, spending time with family and reading.
