In the early 1960s, after his release from prison, Dominique went to work as a program host and cultural commentator at Haiti's first independent radio station, Radio Haïti, interviewing writers and scholars. In 1972, he purchased the lease to the station from Ricardo Widmaïer and renamed it Radio Haiti-Inter. It was the first radio station in Haiti to broadcast political analysis, interviews, and investigative reporting in Haitian Creole, the language spoken by the entire population of Haiti, in addition to French, which was the language of the ruling elite.
