Director of Preschool and Primary

Priscilla Alvarado

My name is Priscilla Alvarado, since I was a little girl, I knew my life was going to be surrounded by children who will fill my days with joy, knowledge and love. My higher education was at the University of Costa Rica, where I could develop two big passions for me which are Arts and Education. I obtained academic degrees in both of them. I first started working in education back in the year 1988 at Metodista School. In 1988, I began working for IEM and then in 2012, I began working at Saint Gregory. I worked first as a teacher and in 2013 as the Elementary Coordinator. During all these years in the administrative area, I have also been actively working as a teacher, giving support to students and teachers and also learning from them.

Saint Gregory has been part of my family since 1999 when my daughter began her academic life. All through my years of teaching, I have worked with children from all ages from preschool to high school, and I have had the opportunity of growing as an educator in both areas, artistic and academic.
