Raymond Parenteau’s fight for his disabled son once led to him being booked in an Arizona jail-and, much later, to owning a multimillion-dollar business empire. The Grants Pass company he co-founded, Rever Grand, is now Oregon’s largest provider of what are known as “direct support professionals,” workers who provide in-home care for people with severe disabilities. The company has had revenues of more than $100 million each year for several years-all of which came from government.
