Our History Dominic Sigillo grew up in San Francisco and began his career in the plumbing industry as a delivery driver for Cal-Steam. In the early 1990s, the plumbing sector took an economic downturn and Dominic was let go from his position in sales. Although Dominic was raising a young family, he also understood a good opportunity. With the years of experience and the relationships he built, Dominic Sigillo decided to start his own plumbing supply company. Sigillo Supply Inc. officially opened its doors in August of 1993. Gina Sigillo, Dominic’s daughter, joined Sigillo Supply, Inc. in 2010 to help develop the family business. After her father’s passing in 2017, Gina took over the business, carrying on the knowledge and expertise San Francisco Bay Area plumbers, contractors and engineers have known for nearly 30 years. With a strong team of plumbing veterans alongside her, Sigillo Supply, Inc. continues to serve and build on both new and established relationships.
