Armando Pérez Roura got his start in radio at the young age of 15 in his native Matanzas, where he was a journalist and radio host at Radio Reloj. He fled the island in 1962 and arrived to the United States

In the 1980s, he founded Radio Mambí in an effort to spew news and commentary that would topple Castro’s regime. Known as a hard-line Cuban exile, Roura made waves across the Cuban community and eventually impressed the larger Hispanic media as well. Purchased and then powered by Univision, Radio Mambí became one of the foremost anti-communist radio stations in Miami.
