Greg's interest in preserving Colorado's most beautiful places has led him to be active in the land conservation community. He was the president of the Mountain Area Land Trust for seven years, and has represented land trusts and landowners in transactions involving the preservation of unique and scenic property through the use of conservation easements and other land preservation techniques. Greg negotiated and prepared the largest donated conservation easement in Colorado history. He is also actively involved in the conservation community as a director of the Colorado Coalition of Land Trusts, a statewide umbrella organization for land trusts and government open space programs. 

As a member of the firm's Renewable Energy Practice Group, Greg is an active speaker on wind energy. In the last year he has given CLE presentations on wind farms to the Colorado Bar Association, NAIOP, the South Metro Chamber of Commerce and Colorado Corporate Counsel. He has also twice taught the Wind Law class at University of Denver, and has represented a wind developer in North Dakota.
