Board of Directors

Our Land Trust is governed by a nine-member volunteer Board of Directors with diverse backgrounds in agriculture, water, wildlife management and nonprofit management.

Larry Vickerman

Larry Vickerman obtained a bachelor's degree from Colorado State University in Landscape Management in 1990 and a master's degree in Not-for-Profit Management from the University of Washington in 1993. He is director of Denver Botanic Gardens at Chatfield, a 700-acre farm and public garden in Littleton, Colo. He has worked in public horticulture and landscape restoration for more than 25 years, and he also maintains an active role in the family ranching business. In 2009, the Vickerman family placed a conservation easement on their 720 acres of ranchland in the southern Wet Mountain Valley. The easement is held by San Isabel Land Protection Trust.

Keith Hood

Vice President
As a fifth-generation Wet Mountain Valley resident, Keith is a working rancher who depends on the health of the land for a profit. He graduated from Colorado State University with a bachelor's degree in Animal Science in 1973. He has one daughter and manages The Hood Family Ranch, an active cattle ranching operation. Keith has been a board member on and off with San Isabel since 2001 and also serves on the Custer County Planning Commission and is the Custer County representative on the Arkansas River Basin Round Table. The Hood Family placed a conservation easement on their ranch in 2004 because it gave the family a chance to preserve the land as undeveloped property while allowing the ranch's operators to continue to make ranching decisions as they have always done. It also provided funding to establish retirement funds and an investment portfolio providing long-term income.

Ann Robey

Born in New Hampshire, Ann has lived in Virginia, Massachusetts, Missouri, Alabama, Georgia, North Carolina and Texas, and has been in Colorado since 1975. After graduating from the University of Missouri with degrees in Political Science and Education, she taught high school in Alabama and Georgia for two years. She worked in the information systems field for Cone Mills in North Carolina, Hughes Tool Texas and Blue Cross/Blue Shield, then Martin Marietta (now Lockheed Martin), in Colorado. She was with Martin Marietta for 20 years, taking early retirement in 1995. Ann enjoys hiking, reading, gardening, traveling and exercise classes. In addition to San Isabel, she is on the boards of Custer 2020, Friends of the West Custer County Library and the Historic Willows School Society. She also volunteers with the Wet Mountain Valley Community Foundation, the Westcliffe Center for the Performing Arts, Custer County Cattlewomen and the High Altitude Garden Club.

He has also developed sub-area and neighborhood plans and co-authored a model land development code for small communities in Colorado sponsored by the Colorado Department of Local Affairs – Office of Smart Growth. Bob moved to Colorado from the Midwest in 1980 and appreciates the varied terrain, expansive vistas and preserved open spaces this state has to offer, as well as the incomparable Wet Mountain Valley. He has been a member of the San Isabel board since 2007.

Steve Oswald

Steve and his wife, Nancy, live on a ranch that has been in Nancy’s family for more than 70 years. After 12 years ranching in British Columbia, they returned to the family ranch in 1991. Augmenting decades of practical ranch experience, Steve is an avid learner on topics ranging from carbon ranching to creating profitable, biodiverse and beautiful landscapes through holistic principles. Steve and Nancy’s management epitomizes regenerative practices designed for resiliency to the challenges of the 21st century. Their innovative grazing and forestry programs, direct marketing of grass-fed beef and low-tech riparian restoration projects increase the sustainability of their operation while also demonstrating that conservation, including easements, helps ensure long-term viability of agricultural operations throughout Colorado.
