What is the history of Altana?
We’re glad you asked! The Altana story is one of our favorites, starting in 1949 when 9 guys in a box car each tossed a 5-dollar bill into a cigar box. The rest, as they say, is history and we’ve been spreading smiles in our communities ever since. Learn more about all things Altana here.
