Nearly a century since Otto Charles Cluss founded his lumber company in 1918, O.C. Cluss continues to thrive and grow as a major regional lumber and building materials supplier. A privately owned company, the O.C. Cluss Group’s day-to-day operations are still run by brothers Christopher Cluss and Michael Cluss, upholders of both the Cluss name and the Cluss philosophy.
