The college's first chancellor and longest-serving superintendent-president, she has reshaped the Valencia campus and created an entirely new one in Canyon Country.

He set a retirement date of his own for Dec. 15, 1982, but he dutifully agreed to stay on until a replacement for Dr. Newcomer could be found. He retired in 1983 and died in Nevada in early 2019.

He arrived during a particularly difficult period for all of California's publicly funded institutions.
