It was post war 1946 when D.J. Lanahan founded Lanahan Lumber Company. The construction industry was at an all-time high in Jacksonville, Florida and Lanahan wanted to contribute to the city he loved. Lanahan had a simple philosophy. Offer the best! It was and is today the Lanahan way: employ the best-trained people, offer the best product, guarantee the best service, and deliver the best quality at the best price. The company continues its family-ownership, with CEO Michael J. Lanahan.
