More than 100 people met Friday at park in Clayton to fight the allegations against James McNamara, who is also known as "Coach Mac."
The parents and the young men McNamara coached at Corinth Holders High School said they are frustrated by the way the Johnston County School Board and sheriff's office has handled the case.
McNamara's mother, who is employed by the school system, made a passionate plea.
"Those who know the accuser, I implore you to seek the truth from her," said Diane McNamara. "I pray for her because I feel she has no insight into the long-term effects of her actions for my son or even her."
McNamara is out of jail on bond and suspended from teaching and coaching.
He is due back in court on April 12. His supporters plan to be in the courtroom.
