The Omicron Mu Lambda Chapter of Alpha Phi Alpha Fraternity, Inc., was founded on April 16, 1986 to serve the city of Marietta and Cobb County.

In its short history, Omicron Mu Lambda has worked as a prominent and guiding force throughout Cobb County. Through its involvement with local organizations such as the Cobb Chamber of Commerce, the Cobb Community Collaborative, 100 Black Men of America – Cobb County Chapter, the March of Dimes, Communities and Schools, Hands of Atlanta, Boy Scouts of America, and the NAACP, the Brothers of Omicron Mu Lambda have consistently followed the Fraternity’s motto of “Service to All”. The national and local programs instituted by Omicron Mu Lambda continue to perpetuate the Chapter’s legacy of excellence.

Project Alpha is one of the premier programs implemented during the Fraternal year and impacts nearly 100 young men annually.

Go to High School – Go to College stresses the importance of a college education to Cobb County youth and provides yearly visits to historically black colleges and universities.

A Voteless People is a Hopeless People works to educate citizens and youth of Cobb on the right and obligation to register, vote, and exact change through the ballot box.

The Chapter regularly supports local Boys Scouts of America troops in providing scoutmasters as well as financial assistance. Lastly, the Leadership Development Institute recognizes the best of brightest youth in Cobb County and provides a forum to build a strong foundation of leadership for the next generation. At the local level, the professional makeup of the Brotherhood has led Omicron Mu Lambda to create a comprehensive Business and Economic Development program. In the implementation of this program, the Chapter regularly examines new ideas and works to perfect existing methods that can lead to economic and financial independence for the Chapter as well as for individual Brothers and their families.

Other local projects such as the Martin Luther King Jr. Celebration, Founder’s Day, Christmas with the Deltas, and Y.O.U.T.H. (Young Organizers United To Help) are other examples of the innovative and unique approaches used by Omicron Mu Lambda to reach and impact the community. The Henry Arthur Callis Education Foundation is a 501(c)(3) non-profit which supports and funds a wide variety of charitable, civic, and educational projects in the Cobb County community. The programs supported by the foundation focus on teenage pregnancy prevention, youth leadership development, and high school/college preparation. Through the Henry Arthur Callis Scholarship program, high school seniors and college undergraduates are regularly considered for tuition assistance via academic and service scholarships.

In 2001, the foundation awarded $10,000 in scholarships to Cobb youth. Omicron Mu Lambda was recognized as the “Outstanding Alumni Chapter of the Georgia District” in 1991 and 1992.
