Anne Arundel County Public Schools chief of staff George Margolies is leaving the school system to take a similar position in Prince George's County, joining former Anne Arundel Superintendent Kevin Maxwell, who left in August to lead Prince George's schools.

Margolies said in an email Wednesday addressed to "friends, colleagues and family" that his last day in the Anne Arundel school system will be Nov. 15.

Margolies said that it had been assumed by many that he would join Maxwell soon after the superintendent left for Prince George's County. He said that the decision to join Maxwell has been a "difficult decision," but added that "now is the time for a new challenge" and "I believe that I can serve the families and citizens of Prince George's County to improve the quality of education delivered in their school district."

Anne Arundel County school board president Teresa Milio Birge applauded Margolies' service to the school system and his efforts in helping Anne Arundel interim superintendent Mamie Perkins transition into the position.

"We will miss him very much. I wish him only the best in his new position in Prince George's County," Birge said. Asked if she knew of any other school system staff expected to follow Maxwell to Prince George's County, Birge said, "I am not aware of other departures on the horizon."
