All this work was done in an inadequate building beside the church of San Hipólito. Father Olleta conceived the idea to build a school only for the hearing impaired with specialized personnel. Father Olleta collected money from religious and non-religious organizations and people. In 1949, he bought a small piece of land and started to build the first Catholic School for the Deaf.

Unfortunately, Father Olleta´s project was interrupted in 1950 because of his death, and the construction plans were stopped. Afterwards, Father Manuel Fierro adopted Father Olleta´s labour, and in his memory founded the Academy Rosendo Olleta for the Deaf in 1955.

At that time the work with the Deaf was focused in two aspects:

1. Religious services, instruction and giving of sacraments.
2. Academic. Elementary education (language, geometry, mathematics, drawing, grammar, spelling, calligraphy and typing), and job training.

In April 1967 Father Fierro was replaced by Father Angel Alegre another devoted clergy. For the firs time the academy had a project and a budget, with personnel and improved facilities to give high quality attention to the school community. During the period of Father Fierro, the Rosendo Olleta Academy had a great technical and organizational impulse. After Father Fierro´s death in 1985, Father Macario Sánchez took the control of the Academy supported by a group of lay people, seminarians, and members of the Deaf community of San Hipólito church. At this time the Academy became Rosendo Olleta Institute.

The Institute has had administrative, technical and operational reorganization. Criteria for student admission since 1985 was created, group of students of similar abilities were formed, and specialized personnel was hired. A pre elementary program was established and standardized curriculum from the Public Education Ministry was implemented. The religious activities of the school were separated from the academic activities.

In 1994, due to the small capacity of the building in downtown, the pre-school and elementary levels were moved to a new location on Del Valle neighborhood. At the building downtown the programs of adult education and job training were continued.The new location was beneficial and the activities of the Rosendo Olleta Institute continued to be based on respect for the language and culture of the Deaf, and promotion of their total development. This was possible with the unconditional help from Fathers Aníbal Carballo and Fracisco Díaz.

The Rosendo Olleta Institute was pioneer institution in using Mexican Sign Language and for promoting services for the Deaf, but in January 1999 the Claretian Missionaries announced the withdraw of their economic support for the Institute and handed it over to the staff and parents from the Del Valle location. Staff and parents decided in August of the same year to create the civil association Institute for the Integral Formation of the Deaf (Instituto para la Formación Integral del Sordo), with the objective to continue the work done by Father Olleta, and to extend the services and perspectives of the Rosendo Olleta Institute.

Now the Rosendo Olleta Institute is administered through the Institute for the Integral Formation of the Deaf, and is totally independent of Claretian Missionaries. The school on Del Valle neighborhood is still named Rosendo Olleta Institute even though the Civil Association manages it. The programs in the building in downtown changed their name to Clotet´s Center.
