Frank Mann, Owner

BS Finance, 1981 University of Alabama. Frank spent 18 years in the Convenience Store industry with 7-Eleven, then with equipment suppliers, then with a smaller (55 store) chain in the Deep South. Transitioning to the related downstream fuel industry, he spent 12 years in the fleet fueling business, ending up with a company he founded that provided specialized fueling services following weather disasters, working in the aftermaths of Hurricanes Ivan, Katrina, Gustav, Ike, Irene, and Isaac, as well as several winter storms. Naturally, opening a Mathnasium was the logical next career for Frank! Frank has 3 kids, two of them Eagle scouts, all of them musically gifted! Married 30 years (to the same wonderfully understanding, ever-patient wife, Deborah), Frank has owned over 40 interesting cars, and if you ever want to know something about Hawaii, please ask, because that is one of his favorite subjects. Frank owns two additional Mathnasium Learning Centers - Mathnasium of North Dallas and Mathnasium of Tyler. Frank apparently likes driving on I-20 a lot.
