Rubenstein Supply Company was founded during the Great Depression by three brothers, Henry, Morris, and Bob Rubenstein. The Company got its start salvaging plumbing fixtures from their father’s building demolition business. Native Oaklanders, they decided to stay local, and built a warehouse at 28th and San Pablo Ave. The brothers built a wholesale plumbing distribution business which they operated together for forty plus years. Henry and Morris retired in 1986. At that time Bob and his son Craig, who joined the company in 1969 after graduating from UCSB, bought Rubenstein Supply. They operated the company together until 2002 when Bob retired, and Craig became the sole owner. Under Craig’s leadership, the company has seen tremendous growth over the years.
In 1991 Matt Laiolo joined the company. Matt graduated from Saint Mary’s College in 1989 with a B.S.in Business Administration and Economics. He attended Graduate School and coached baseball at St. Mary’s from 1989-1991. Matt started at Rubenstein supply driving a truck, working in the warehouse and yard. He continued his growth over the years manning every position at Rubenstein and currently holds the position of President, which he has held for several years.

The counter person was incredibly patient with us, answered questions by phone and generally was very supportive. Pricing was comparable to online stores.
Yes it is not a showroom and caters to contractors. But we are now big fans (relative to Moran especially which was not helpful)
