Dixon graduated from Huffman High School in 1976 and worked for AT&T until 1983, when he founded his own company. Dixon has served nine years on the Jefferson County Planning and Zoning Commission, including more than two years as chairman.
In 2010, Dixon was one of five candidates to qualify in the Republican primary to fill the Jefferson County Commission District 4 seat left open when four-term incumbent and Commission President Bettye Fine Collins decided not to run for re-election. In the primary, Dixon's 22 percent of the vote put him in the runoff with Trussville lawyer Joe Knight, who received 32 percent.
