Brenda Diederichs has taken over as Riverside County’s human resources director.
Diederichs, who began work earlier this month, also holds the title of assistant county executive officer, according to a statement.
Formerly Orange County’s chief human resources officer, Diederichs has more than 20 years experience in management systems, labor negotiations, and policy-contract development.
She was Riverside’s human resources director for two years, and for seven years served as executive officer for labor-employee relations and human resources with the Los Angeles Metropolitan Transportation Authority.
Diederichs replaces Michael T. Stock, who retired in February after five years as director, according to the statement.
