Omega Phi Alpha's letters were chosen because of our National History being started by the Zeta Kappa Chapter of Alpha Phi Omega at Bowling Green State University. The Zeta Kappa chapter of APO was looking to create another organization to help them with service projects, and a lot of women were interested in being apart of it. So they created a service sorority and chose a similar name: Omega Phi Alpha.
