Donna Hathaway-Beck, one of the longest-serving members of the Prince George’s County Board of Education, announced Wednesday that she plans to resign from the panel.

Board chairman Segun Eubanks said Hathaway-Beck’s resignation is effective Sept. 6.

Hathaway-Beck (District 9) said her decision was based on personal reasons, trying to juggle being a grandmother and a board member.

“It has been too hard dealing with a growing family,” Hathaway-Beck said, noting that she has had four grandchildren added to her family since 2009.

Hathaway-Beck, who has served for seven years, was part of the new school board that was elected after the appointed board was dissolved.

She is the second board member to resign in less than two months. Carletta Fellows (District 7) cited personal reasons in her resignation last month. Fellows’ decision came after a closed session where board members discussed her background check and unauthorized credit card charges, according to two people familiar with the proceedings.

“She had been talking about it for a while,” Eubanks said. “I didn’t think she would pull the trigger, but she did.”

Hathaway-Beck, known as a government watchdog, ran for office after recording what she called a perfect attendance at school board meetings for nine years.

“She’s definitely a staunch advocate who speaks her mind and comes with a non-partisan approach,” Eubanks said.
