The four-store Jurgensen's specialty grocery chain, which at one time had 22 stores from San Francisco to La Jolla, is being sold to Ojai Capital, a partnership whose principals include longtime Pasadena residents who have shopped the stores. "We look at Jurgensen's as part of the Southern California heritage," said Kenneth S. McCormick, director of Ojai Capital, which announced the purchase agreement. Jurgensen's, based in Pasadena, has undergone big changes in the last two years. In 1986, an agreement was reached to merge with Yucaipa Capital Corp., just three months before the death of founder Harold S. Jurgensen at 78. In addition to Pasadena, Jurgensen's has stores in Santa Barbara, Beverly Hills and the Jonathan Club in downtown Los Angeles. The purchase price has not been determined, McCormick said.
