Arlington County school board member Noah Simon resigned Tuesday morning, effective Aug. 1, in order to spend more time with his young children.

Simon, a former Capitol Hill staffer and American Red Cross employee, joined the board in January 2013 and served as its liaison to the student advisory board.

A year into his term, Simon’s wife, Kedron Veliz Simon, died from intestinal cancer. In a statement announcing his resignation, Simon wrote that he wanted to spend more time with his children, Jackson and Madison, students at the Arlington Science Focus School.

“I believe the only reason to give up something that you love like my school board work is for somebody you love like my kids,” Simon wrote. “Simply put, the demands of this job have made me a part-time father. My kids need and deserve my full attention during this difficult time, particularly on school nights when so much of the board’s work occurs.”

Simon moved to Arlington in 2003. A native of Rochester, N.Y., he was a graduate of Gettysburg College. Before his election to the school board in November 2012, Simon had served as a PTA president and liaison to the county council of PTAs. His wife was a Harvard graduate and Navy veteran who attained the rank of lieutenant commander.

School board chair James Lander offered gratitude on behalf of the board to Simon for his work.

“We want to thank Noah for his tireless and exceptional commitment to the school community, especially in the midst of the grief he and his family have experienced during the past few months,” Lander wrote in a statement. “We understand and support his difficult decision to resign, and were fortunate to have such a passionate and committed colleague on this board during the time he served.”

The county will hold a special election to fill Simon’s vacant seat after Aug 1.
