Dr. Alison Sheets is an emergency medicine physician working in Boulder Colorado and is a self proclaimed search and rescue (SAR) geek. Prior to her medical career she worked as a bartender, an electrician, a mountain guide and a ski patroller. She currently holds leadership level positions in the Mountain Rescue Association (MRA), the Wilderness Medicine Society (WMS), the International Commission on Alpine Rescue (ICAR) and the Colorado Army National Guard Hoist Rescue Team (CHRT). Despite the administrative roles she has personally responded to over 120 rescue mission call outs in 2020 for her home SAR team Rocky Mountain Rescue Group in Boulder. This is all done as a volunteer. With her varied background she brings a practical approach to SAR emphasizing team work and situational awareness. The emotional well being of first responders, the delivery of excellent medical care in the SAR environment and the technical challenges of rope and avalanche rescue are other areas of special interests. An avid bird watcher, Dr. Sheets appreciates the complexity and importance of trees.
