Onno Wieringa was born and raised in Conrad, Montana and graduated from Montana State University with a B.S. in Commerce in 1972. In 1976, Onno and two partners founded Glacier Raft Company in West Glacier. In the ensuing years started Glacier Raft Operations in Polson on the Lower Flathead, in Idaho on the Lochsa River, and in Canada on the Kicking Horse River. Additionally, the trio partnered with Adrift Adventures in Moab Utah. By 2000 they consolidated all operations to West Glacier and developed the Glacier Outdoor Center. The Center has cabins, a lodge, an events center, outdoor equipment rental, fishing, and retail. In 2015, Onno moved out of daily operations and is still a partner in the land and facilities.
From 1988 until 2016, Onno was General Manager of the Alta Ski Area in Utah and was responsible for all operations and business development. In 2008, Onno founded the Alta Environmental Center as a ski area department to not only add process and measurement to environmental and stewardship projects, but to also have projects be financially responsible to help assure their sustainability.
Additionally to his general experience, he pursues quality experiences from rafting, ski areas and life. He often says it comes back to capacity, over-capacity and under capacity and how capacity affects everything around it.
