Kellie Prinz Johnson has been on the Diamond M Club board since 2012. She has served as secretary, treasurer, vice president, and is now the president. Kellie and all of the current board members have worked to expand the membership beyond alums of the Mustang Band and leverage technology, social media, and strategic planning to continue to set records for both membership and revenue each year. Kellie was in the Mustang Band from 1992-1996, played the alto sax, and was a squad leader for 3 tumultuous years, all of which had a different band director at the helm. When not passing out flash drives and pestering people to join the Diamond M Club, Kellie is the Director of Operations for Retro Studios in Austin, Texas. At work, she’s basically the Mom to 95 video game developers. At home, she’s the Mom to 2 sons. Kellie, Kevin, Jacob, and Samuel live in Round Rock, and make the trek to Dallas A LOT.

Brian Waddle joined the Diamond M Club board in 2015, where he serves as in-residence branding and marketing guru.  Brian won't confirm when he joined the Mustang Band, only that he graduated from SMU in 1993.  He stayed on campus for one more year to work as Assistant to the Director in 1994, during which time he helped start the expanded Mustang Band drum line in its current format.  Currently, Brian is the director of brand management for the Houston Community College System, one of the largest singularly-accredited higher education institutions in the nation. He's also a travel writer for OutSmart magazine and husband to UH grad Kevin Hamby, which makes for fun game days in October.  One of his proudest moments with the Mustang Band was conducting the national anthem at the Rose Bowl for the 1994 SMU-UCLA  game.
