Margaret Wheeler learned to ski and climb at an early age in New England, and became interested in ski mountaineering while living in Europe for several seasons. In 2006, Margaret became the second woman in the US to complete her full AMGA IFMGA guide certification. An active member of the guiding community, Margaret is an instructor of guide
training for the American Mountain Guides Association (AMGA) and serves on its board of directors and as president of the organization. She is involved in avalanche education through her work as an AIARE (American Institute for Avalanche Research and Education) instructor and trainer.
Margaret is the proud owner of a fully functional disco ball, and when in the US she and her husband can be seen driving a ginormous yet slender silver van (named Hedwig) around the western states.
