Dave Olsen completed a cob workshop led by Ianto Evans in 1996 and has had mud (and sourdough) on his hands ever since. He began hosting Natural Building workshops in 2007, began instructing the revolutionary "Fast Cob" mixing and building methods in 2009, and turned 50 in 2013. Based on off-the-grid Lasqueti Island, he also hosts an apprenticeship that goes well beyond Natural Building, helping younger people develop responsible and environmentally sustainable lifestyles with enjoyment and ease. Dave has been very fortunate to have worked with many of the leading cob builders of our time and to have a dynamic, cob- and bicycle-loving daughter (and dog!).
