Campbell and fellow Dorchester resident, Bill Walczak (Barr Fellow Class of 2007), got to know each other working on a 1985 campaign to fight billboards advertising tobacco and alcohol near neighborhood schools. The campaign proved successful, and the two became friends. In 2000, when Campbell heard Mr. Walczak was looking to expand the health center's youth programs, the activist duo had found a new cause. Codman Academy has an ongoing relationship with Codman Square Health Center.
