RODNEY EDMISTON brings over thirty-five years of construction knowledge to Mason Hammer Builders. Rodney started his construction career when he was only fourteen, when he began laying masonry block for his grandfather in rural Wyoming. Rodney has been running construction projects since he was twenty-four, and opened his own masonry company when he was thirty-two years old. He moved to Northern California in the 1980s and his company built many of the masonry sound walls and shopping centers around the Bay Area. In the late 1990s he retired his masonry company and started building residential projects. He continues to build multi-million dollar homes in some of the finest neighborhoods, from the vineyards of Morgan Hill, to estates and contemporary homes in Los Altos, Atherton, Palo Alto,  Los Gatos, Saratoga, Monte Sereno, Ruby Hills, and many other cities in the Bay Area. Rodney is known for his direct approach, his attention to detail, and managing his projects while efficiently delivering them on schedule and on budget. He takes great pride in his work and with the relationships formed with past project owners.
