Alpha Kappa Sorority Inc., Phi Alpha Omega Chapter, and the Tea Rose Foundation of Northwest Arkansas presented the 23rd annual Celebrity Waiter fundraising event Oct. 22 at the Embassy Suites in Rogers. The benefit is an opportunity for the groups to laud " Difference Makers who have transformed and enriched the Northwest Arkansas community, Dr. Margaret Clark, the first African American woman to receive tenure and have a residential hall named in her honor at the University of Arkansas, and Dr. John L Colbert is the first African American superintendent of Fayetteville Public Schools," organizers say.
