[1] After Bachillerato studies in Matanzas, he trained as a dental surgeon and practiced as such for three years (1954–1957), dividing time between the job and his literary vocation.
[4] After directing an adaptation of Lope de Vega's La discreta enamorada, he wrote La dolorosa historia del amor secreto de Don José Jacinto Milanés, a literary work that required him to do complex research into Spanish colonial Cuba.
At this point his output constituted an intimate journey through the intricacies of the human being as part, for good and for bad, of that social structure that is the family, the core on which Estorino focuses to look at the reality of society as a whole.
This explains why many of his plays were successfully performed in theaters in Europe (Norway, Sweden, Spain) and the Americas (United States, Chile, Venezuela).
In the 1980s, his works included Ni un sí ni un no, Pachencho vivo o muerto, Que el diablo te acompañe (1987), Las penas saben nadar (1989), and Morir del cuento, whose production was awarded in Spain, at the Theater Festival of Havana,[4] and by the National Union of Writers and Artists of Cuba.
