Considering Gov. Sam Brownback's aggressive reform agenda, it's no great surprise that Social and Rehabilitation Services Secretary Rob Siedlecki (in photo) is making major changes in the state welfare agency. According to an SRS statement, the personnel changes are intended to support Brownback's goals and Siedlecki's "family-centered initiatives." But they also sweep away a tremendous amount of institutional knowledge at an agency responsible to protect abused children and deliver services for Kansans with mental illness, developmental disabilities and other challenges. Jean Hogan, the respected regional SRS director for Wichita who was among those ousted last week, told The Eagle: "I want the community to know how important it is for SRS to be the eyes and ears for the safety and protection of children." Do Brownback and Siedlecki know how important that is? Legislators and social services advocates must watch closely to ensure this "new day at SRS," as Siedlecki called it, does not lead the agency to neglect its core responsibilities.
