Dyann Mack, who had been functioning as Harford Schools’ acting superintendent since early January, was officially named interim superintendent Wednesday by the Board of Education.

Mack took the school system’s helm after former superintendent Sean Bulson was suspended with pay in January amid an investigation into a recorded 911 call he made to New Orleans Police in April 2024. Bulson reported an apparent theft of about $8,000 worth of school-owned equipment from his hotel room while he attended an education conference. The items ended up being found in his hotel room safe.

On Feb. 9, the school board voted to terminate his current contract, which was set to end June 30. Mack will serve as interim superintendent through June 30.

Bulson’s contract states his annual salary was $293,220. Mack has not signed a contract yet with the school system, according to the manager of communications for HCPS, Jillian Lader, and her salary information was not available. Once a contract is signed, it will have to be approved by the state’s superintendent.

An acting superintendent is a “short-term immediate filler to ensure legal continuity during a sudden vacancy,” according to board president Lauren Paige. An interim is a “temporary contracted leader hired for a longer planned transition period to manage operations while a permanent replacement is sought,” Paige said.

Mack, a Joppatowne High School graduate, has worked for Harford Schools for more than 30 years, most recently as deputy superintendent for academics, leading curriculum, instruction, professional learning and student support services.

She began her career in Harford County Public Schools as a teacher at Prospect Mill Elementary, then became an achievement gap coordinator, assistant principal and principal.

The district’s search for a new superintendent is underway.
