Silicon Valley brokerage buys ex-NFL star's endorsement

49ers legend Dwight Clark will represent Intero Real Estate

Retail manufacturers put great stock in the ability of athletes and other celebrity endorsers to help them move shoes, sports drinks and other goods off of store shelves. Now a real estate broker in California’s Silicon Valley is betting that a former San Francisco 49ers star who made a famous catch 30 years ago can help the firm sign up clients and sell homes.

Cupertino, Calif.-based Intero Real Estate Services Inc. President Gino Blefari hopes NFL football legend Dwight Clark, the firm’s new celebrity endorser, will be as good for his business as he was for generations of San Francisco Bay Area fans.
