At the Kalahari Resort hundreds of school safety professionals came to listen to Lieutenant Colonel Dave Grossman.
For year's he taught military personnel and served as a psychology professor.
"School safety is an ongoing process. It shouldn't take a tragedy like parkland to make as take this topic seriously,” said Grossman.
Grossman spoke about different ways to prevent violence in schools, including adding armed officers to campuses, enforcing a stricter dress code, addressing mental health needs and bullying.
He even talked about arming teachers.
“We're not saying its right for your school, but it's one of the things to consider,” said Grossman.
After listening to Grossman, one school district leader would like to see changes to school buildings.
"It’s all about a multiplicity of strategies you can arm teachers or give them something to defend themselves with, but part of that strategy needs to be the hardening of the building, make sure it's harder for someone on the outside to get in,” said Robert Ellis, East Troy Community School District.
While there isn't one solution to stopping school violence, many say school safety always need to be a top priority.
