Our History

San Roberto International School opened doors as a preschool in 1982, founded by Monica Sada, under the name Instituto San Roberto. Activities began in a small rented house in San Pedro Garza García, Nuevo León. The name “San Roberto” was chosen in honor of Mr. Roberto G. Sada Jr., one of Monterrey’s most distinguished businessmen and father of Mrs. Sada. Success in the preschool levels led to the opening of the elementary levels a year later, adding a bilingual program.

The increase in the student body and the need for new facilities led to Mrs. Cristina Sada, the founder’s sister, to join the school as an investor. The new San Agustín opened in November 1984. Middle school levels opened in 1989.

To serve the growing population in the southern part of the city, Valle Alto opened its doors in September 1994.

Both campuses were accredited by the Southern Association of Colleges and Schools (SACS) in December 2002, and currently hold the accreditation by SACS, now as a division of AdvancED.

Since the beginning, ISR has been a values-focused institution, and the robust Values and Character Education currently in place is a result of more than 30 years of mastering this subject.

La Gloria Project is a key part of the ongoing social responsibility activities that take place at the school. La Gloria is an underdeveloped community in Coahuila, Mexico that San Roberto has been helping since 2007.

ISR’s values and character education pledge goes beyond the classroom, and aims to create awareness of the social responsibility and commitment needed to construct a better Mexico.

As a solution to this pledge, the ISR Values Conference was created in 2012. Middle school students from all over the country attend this yearly event, which combines keynote presentations, workshops, and activities revolving around themes like: character education, social responsibility, and values. Notable past keynote speakers include: Kim Phuc,Katie SpotzDr. Sameer Hinduja, and former first lady of Mexico, Margarita Zavala de Calderón.

In June 2015, San Roberto joined Nord Anglia Education, the world's leading premium schools organization. Now, we are part of a global family of 73 international schools, providing outstanding education to over 67,000 students in 30 different countries from preschool through to the end of secondary education.

As part of Nord Anglia Education, our students and staff became a part of a vibrant global community, have access to expanded resources and benefit from the support of world-leading educational experts.

Under the leadership of Nord Anglia Education, Instituto San Roberto transforms to become San Roberto International School as of September 2015.
