Colegio San Benito ("CSB") is a private Roman Catholic, university-preparatory and elementary school, founded in Mayagüez, Puerto Rico in 1965.

During the conversation, General Trujillo offered to establish in the Republic of Santo Domingo in the Dominican government's expense, a Technical College, to later donate it to the community of Samos.

Residing in Humacao, they'd established contact with the industrial Ramón Arbona, who shows them the idea of a school in Mayagüez, in honor of his son, who died in a plane crash.

In order to have closer relations these two parents moved to Mayagüez, and Bishop McManus put in charge of the church of the Sacred Heart.

Thanks to the devotion of parents who gave the opportunity to their sons to be educated in the first school for boys in the city and the group of teachers who were pioneers in determining the start of San Benito made the new institution very welcomed as it has been for years.
