Upon his return from the United States, Verano started a career as a business administrator, combined with his militancy in the Colombian Liberal Party.
In December 1990, representing the Colombian Liberal Party under the support of Horacio Serpa, Verano ran for a seat in the Constituent Assembly of Colombia and was elected.
Between 1992 and 1994, Verano served as general manager of the Corporación Eléctrica de la Costa, Corelca, the electric company that controlled the energy in most of the Caribbean Region of Colombia.
After the triumph of Liberal party candidate Ernesto Samper for the presidency of Colombia in 1994, Verano postulated himself for the Mayorship of Barranquilla but was defeated by Edgar George.
Verano then decided to participate in the 2007 Colombian regional and municipal elections of 28 October by postulating his name for the Governorship of Atlántico Department.
