Since that time, the group has worked to educate and activate members of the community.
"There is a huge amount that can happen on a local level to actually improve the world for peace and justice," said OMNI President Gladys Tiffany.
OMNI members say their calling is sometimes misunderstood.
"Peace isn't just about lack of war," said Michelle Murphy, the youth programs coordinator.
"Our mission is to educate, empower and connect for a world that's non-violent, sustainable and just," said Tiffany.
The center is working to ensure future generations feel moved to make an impact, through opportunities at the University of Arkansas and various summer programs.
"We really want to empower youth in this community to see how they can get involved at a local level and really take action and make a difference," Murphy said.
Like learning more about local food sources.
"We've sort of been raised in the TV dinner generation," said Murphy. "Young people are really interested in finding out where their food comes from."
The OMNI Center also focuses on issues like pollution, workers' rights and justice.
"People may call us liberals and maybe they're right, you know, I can't really argue that. I think that what our real intent is to look for the common ground, we have to reach out to each other because we are all in this together," said Tiffany.
It's that sense of unity that motivates this group to improve Northwest Arkansas, and the world around them.
