Sam Betrous


Sam has been with Ravacast since its inception when he joined the company as a draftsman in 2002. As he grew more familiar with precast concrete & GFRC materials, he soon found himself handling the bulk of Ravacast's custom design work, specializing in profile creation, entry surround design, and templating of existing ornamental cast stone features (for duplication and restoration). With over fifteen years of hands-on experience in the architectural precast concrete & GFRC field, Sam has become one of the industry's foremost consultants on the West Coast. When he's not working with his team at the shop, Sam enjoys collecting records, making music, and spending time with his family in Santa Cruz, CA.
