Bill Ingram knows a thing or two about a good burger. As president and CEO of White Castle Systems, Ingram is the head of White Castle Hamburgers. He began working for the company in high school and trained as a counter clerk after graduating from BGSU. From there, he moved into the accounting department. Ingram was elected White Castle’s assistant treasurer in 1975 and was named CEO in 1979. He succeeded his father in running the Columbus-based chain, which was started by his grandfather more than 75 years ago.
