Anna Drexler-Dreis, Programs Manager

Anna’s personal commitment to the environment began during her childhood, running and hiking the shores of Lake Michigan and Cape Cod. Finishing high school early, she traveled to the South Pacific to work on organic farms, which she revisited after graduating with a B.S. in Natural Resources Management from Colorado State University. Her love for studying and protecting the environment was reaffirmed when she worked for the Colorado State Forest Service studying the mountain pine beetle epidemic in northern Colorado. Now, working to protect Grand County’s open space, water, wildlife and agricultural values through conservation easements could not be a better fit for her. She loves to summit peaks, telemark ski, work in her gardens, and run in the forest. Anna currently has a Master’s Degree in Environmental Management from Western State Colorado University, where she coordinated a stream restoration project on the Fraser River. She also sits on the Board of Directors for the Colorado River Headwaters Chapter of Trout Unlimited.

Tiffany Gatesman is an environmental scientist with an MS in Environmental Chemistry from the University of Alaska Fairbanks and a Bachelor of Science in Water and Soil Resource Management from the University of Wisconsin Stevens Point. She has spent her professional years working for the USFS, USFWS, USACE, county governments, and secondary science education. Gatesman’s work concentrates on hydrogeochemistry and water resource management that includes research projects conducted in Wisconsin, Alaska, and Guatemala. 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.


Ashley Krupp, Development Coordinator

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.



Diane LeDuc, Bookkeeper/Office Manager


Originally from upstate NY, Diane moved to Colorado to attend Colorado University in Boulder.  After experiencing the incredible beauty and the great outdoors of Colorado, and graduating from CU, Diane moved to Grand County in 1980 to ski, bike, hike and camp. 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. Diane has volunteered with NPLD for many years, adopted trails, and worked with the food bank among other volunteer activities. “Because of my love of the great outdoors and the natural beauty of Grand County, it’s been a privilege to work for Colorado Headwaters Land Trust. Not only has this given me the opportunity to use my accounting degree; I’ve also had the pleasure of working with some very special people working hard to preserve and protect the land we all cherish so much.”
