BISMARCK, N.D. - Four generations have been keeping the tradition alive at A&B Pizza.
Fifty years ago, Alvin Heier and Barb Barth founded the company.
It's now expanded to four locations in Bismarck and Mandan, and the family runs them all.
"It's really awesome that it made it 50 years. Family has been working at it the whole time. It's pretty impressive that we all stuck together and made it this far," said Nick Barth, manager.
A big celebration is planned for Monday through Thursday next week.
