After years working as 4th District Supervisor Joni Gray’s executive assistant, Susan Warnstrom has retired. Warnstrom was active on the board of the Lompoc Housing and Community Development Corporation (LHCDC) since its inception in 2006, serving as its president in 2010. A grand jury report criticized the county government for a lack of oversight of the LHCDC as part of an ongoing investigation of the corporation’s use of funds. Neither Gray nor Warnstrom could be reached for comment about Warnstrom’s retirement.
