Posey graduated from Hoover High School in 1995 and studied broadcast communications at UAB, completing his bachelor of arts in 2001. He worked as an editor and producer at WBRC 6, WTTO 21, WABM 68 and WVTM 13 until 2004 and spent two years as an editor and photographer for Diamond Studios, before taking his current position in 2006.
Posey campaigned for the Place 1 seat on the Hoover City Council in the 2016 Hoover municipal election. Among his priorities were increasing funding for Hoover City Schools and supporting the arts. He defeated Trey Lott in a runoff. With his support the city did increase its allocation to the school system and established the Hoover Arts Council, to which he serves as a liaison. He ran for re-election in the 2020 election, asking voters for a chance to continue his work for schools and arts, as well as infrastructure and retail redevelopment.
He and his wife, Emily, have two children.
