"Not One More, Art Against Violence" showcases about 80 pieces of art including photos, paintings, sculptures and even T-shirt art.
The Cleveland School Massacre in Stockton saw a gunman kill 5 children and wound 32 in 1989.
Retired teachers from that school formed Cleveland Remembers and the group is sponsoring this show.
Judy Weldon taught second grade and while she says she will never forget that tragedy, she hopes the art will help people find ways to change the culture of violence.
"Time for Stockton to step up and make some difficult decisions. If it's putting away the guns and locking them up, that's what we need to do. We're not saying no guns, we're saying keep the guns safe. Keep them away from the children."
The free exhibit at the Plants and Flowers Building at the San Joaquin County Fairgrounds in Stockton runs throughout the month of March.
