He lives with his wife (a semi-retired psychiatrist) and three dogs in the foothills of the Rockies in a Ponderosa pine forest, on which he practices sustainable forestry for fire mitigation and for his home’s biofuel back-up to geothermal and solar panels. He leads groups into the canopy and teaches climbing skills as Tree Climbing Colorado, LLC.  Harv is one of about a dozen recognized master recreational tree climbing instructors in the world and was founding president of the nonprofit Global Organization of Tree Climbers (GOTC).

Deborah Segaloff, Ph.D. (Treasurer)

Dr. Segaloff is a biomedical research scientist who recently retired from a position as Professor of Molecular Physiology & Biophysics and a member of the Holden Comprehensive Cancer Center at the University of Iowa School of Medicine. Her research was in the field of reproductive endocrinology, with certain aspects of her studies interfacing with cancer research.

For many years Debbie has been concerned about the increasing threat of human-caused climate change. Upon retiring and moving to Colorado, she quickly learned of environmental issues specific to this area and, from a personal perspective, very close to home. Firstly, there is Rocky Flats, a former manufacturing site of plutonium triggers for atomic weapons. Not only was the industrial site only minimally cleaned up after is closure, areas surrounding the site were not cleaned up at all and remain contaminated with plutonium and other carcinogens, thereby posing significant health hazards. Secondly, in Colorado there is extensive oil and gas development, including in more recent years hydraulic fracturing, activities that pose risks not only to our environment and climate, but to our health as well. In light of these issues, Debbie has become actively engaged in education and advocacy for public health, viewing these actions as increasingly vital to securing a safer environment for ourselves and for future generations.
