Andrea Dannette Oates was born and raised in Plains, Georgia. Andrea took office in 2008 after a councilor resigned. She later won a contested election the following year in 2009 for the seat. She currently serves as the Chairperson of Public Relations and Co-Chair of Public Safety and Streets and Subdivisions.
Before settling in Plains, Andrea earned a BS in Electrical Engineering from Howard University in Washington, DC and a MS in Biomedical Engineering from Case Western Reserve University in Cleveland, Ohio. However, she moved back to Georgia to be near her mother, Councilor Brenda Oates Pickett, in 2000. In Atlanta, Andrea taught mathematics and physics at Morehouse College, Morris Brown College, Clark Atlanta University, and Mays High School. Upon returning to Plains, she was employed as a high school mathematics and technology instructor with Sumter County Schools. She is currently the mathematics instructor at South Georgia Technical College and co-advisor of the student chapter of Phi Beta Lambda.
As she serves her community as a councilor, her mother is her inspiration. The Late Councilor Brenda Oates Pickett was the first African-American official in the City of Plains and served as Mayor Pro Tempore at the time of her passing. (In fact, Andrea sits in the same council seat her mother first occupied decades before her passing.) Councilor Pickett was honored for her relentless service despite fighting a debilitating sickness. A street, "Brenda Pickett Circle," was named after her. A bench in downtown Plains and a Certificate of Special Congressional Recognition were dedicated posthumously.
Councilor Oates is the President and Founder of the Brenda Oates Pickett Memorial Organization that tends to the elderly and serves the youth in Plains. She is also an ordained elder and is the Church Editor of the AmericUSumter Observer. She is also a member of the NAACP.
