Mark Wood
Billing / Administration
Hi, I’m Mark. I take care of billing and administrative work on the back end, organizing paperwork, keeping records straight, and making sure all the numbers line up where they should. I’ve been with the company for two years and I really like the steady rhythm of the work and the team I get to work with every day.
When I’m off the clock, I usually end up reading, working on some writing, or playing guitar at home. Quiet, creative things are my idea of a good time.
