OUR STORY

President

Founded in 1996 by Dean Potts, Bonanza Plumbing was built on a simple philosophy: provide quality workmanship, treat customers with integrity, and stand behind every project. After working alongside Dean for more than 20 years, Ray Goldsboro purchased the company in 2017 and continues to build on that legacy.
Today, Bonanza Plumbing partners with many of Southern California’s leading homebuilders, providing complete plumbing installations for new residential communities, multi-family developments, custom homes, service and repair, warranty support, and water treatment solutions.
As we celebrate our 30th Anniversary in 2026, we remain committed to the same values that have guided us since 1996—quality, integrity, reliability, accountability, and customer satisfaction.
