Between the years 1973 and 1977 the entrepreneur Aderson da Costa Gomes, the Casas Guri, clothing store and varieties that worked at Rua Maciel Pinheiro, becomes president of the CDL.  It was a time of great change in the entity, which was growing and gaining more space thanks to its hard work in favor of the development of local trade. The entity was in the process of acquiring its own building and Aderson shared its attention in the administration of the then "Club of shopkeepers" and also of its store.
