Founded in 2011 by third-generation paving contractor Zack Peterson, North Bay Grading and Paving continues a family paving history that began in Sonoma County in the early 1960s. Peterson started working alongside his father at age 8 and earned his contractor's license at 18.

"What I say is what I do," Peterson said. "If I tell a customer they're getting two and a half inches of asphalt, they're getting two and a half inches after compaction."
