Since moving to Jackson Hole, Wyoming, in 1976, his work as a naturalist, wilderness outfitter and guide, along with his camera work, have given him an intimate knowledge of Yellowstone and Grand Teton National Parks and the surrounding wilderness. His desire to share this landscape propelled him to become a photo-educator, teaching workshops in the field and in local schools. Greg's film and video work includes award-winning nature documentaries for National Geographic Television, National Geographic Channels, PBS, the BBC, and NHK Japan. His reels range from endangered ecosystems to hummingbirds, and from the de-listing of Grizzly Bears to the complex lives of Mountain Lions. His passion for adventure led him to produce and film "Acceptable Risk", the definitive documentary on high mountain rescue in the United States.
Greg's love of learning and travel resulted in journeys to a world-wide variety of subjects: endangered landscapes and their wildlife, the colorful gauchos of Patagonia, migrating arctic birds, and the inspiring Buddhist monks of the Himalaya.
