South Dakota Gov. Larry Rhoden has named Brenda Tidball-Zeltinger interim secretary of the Department of Social Services, putting the agency’s deputy secretary and chief of operations in charge during a leadership transition. The appointment took effect October 16 after Matt Althoff left the post.
Tidball-Zeltinger moves into the interim role from a senior operational position rather than arriving from outside state government. The department’s program directory lists her as deputy secretary and chief of operations, while the agency’s updated homepage identifies her as interim cabinet secretary. Rhoden’s office did not announce a timetable for selecting a permanent successor.
A broad service portfolio
The department administers programs that touch residents at different stages of life, including Medicaid, child protection, child care services, child support and behavioral-health functions. Its public directory also assigns the secretary responsibility for administration and direction across the department. That scope makes continuity important even though the appointment is temporary: policy decisions, provider payments, eligibility administration and regulatory work continue while the governor considers longer-term leadership.
Althoff had led the agency since 2023, when former Gov. Kristi Noem appointed him. The governor’s announcement thanked him for the time, travel and work involved in directing the department but did not provide a reason for his departure. Independent coverage by South Dakota Searchlight likewise described the change as a resignation and noted Tidball-Zeltinger’s elevation from the deputy position.
The change is administrative, not a transfer of programs to another department. DSS remains the state cabinet agency responsible for its existing portfolio, and its public contact structure has not been replaced. The governor’s release framed the appointment around service continuity and improved outcomes, while offering no separate policy package. That distinction matters because a leadership announcement can signal priorities without itself changing benefits, eligibility standards or statutory duties.
What remains unsettled
The interim designation preserves day-to-day authority, but it leaves several governance questions open. The governor has not said whether Tidball-Zeltinger will be considered for the permanent job, when a search will begin or whether the administration plans broader structural changes. No new program directive, budget revision or eligibility change accompanied the personnel announcement.
For residents and providers, the immediate practical point is that existing DSS channels remain in place. The agency continues to direct the public to its Medicaid portal, child-abuse reporting system, child-support services, provider resources and constituent liaison. Tidball-Zeltinger’s prior operating role may reduce disruption because she already worked across the department’s internal administration.
The transition also places attention on how the administration defines its next phase for social services. Until Rhoden names a permanent secretary or supplies a timeline, Tidball-Zeltinger has full interim responsibility for maintaining services and managing the agency’s extensive state and federal program obligations.
