Social media firm adds president/COO

SDA Media, an advertising technology and social media marketing firm, is adding Brian Mefford as president and COO.

Mefford joins the Brentwood-based company after a stint as the head of innovation and entrepreneurship for the Commonwealth of Kentucky and as CEO of the nongovernmental Commonwealth Center for Commercialization. (That relationship led to friction when a new governor came into office last year.) Mefford previously led broadband services firm Connected Nation and taught at the University of Kentucky’s Gatton School of Business and Economics.
