Tiffany’s passions for the environment lead her to become involved with Grand County’s water resource issues. With her teaching, scientific, and agriculture background, Gatesman seeks to further the development of the environmental and agricultural education in Grand County. She sits on the Board for the Upper Colorado River Watershed Group and is excited to pursue land and water conservation work as a team member of the Colorado Headwaters Land Trust. Gatesman originally moved to Grand County to take photographs for the rafting companies. After moving away to earn her graduate degree in Alaska, Gatesman, her husband, and two Alaskan sled dogs moved back to Grand County for the love of the abundant recreation in the county such as skiing, biking, hiking, boating, rock climbing, and horseback riding.

Inspired by the active Colorado lifestyle, Ashley and her husband moved to Grand County in 2009. They are grateful for everything the mountains have to offer, including skiing, hiking, and mountain biking. Originally from northern Ohio, Ashley has an English degree from Ohio University. Her previous non-profit experience includes working as the Assistant Director and lead teacher at a local non-profit preschool. Ashley’s motivation to support land conservation stems from this experience – we must be proactive for the benefit of future generations.

She has worked as a ski instructor for disabled children and adults at Winter Park and Granby Ranch. Other vocations have included management positions at restaurants and hospitality.
