Meet Cecilia
Spanish teacher, author and creator of Mamaestra. From Ecuador to San Francisco.
It all started with a game
Cecilia Guerrero began this bilingual challenge as an au pair for two families. She also supported students with young children at home to start this journey on their own.
She has taught Spanish for 20 years and owns the Middle of the World Spanish School. Mamaestra is the program she created to help parents and teachers support their children's bilingualism, combining original materials, real family experiences and years of supporting Bay Area families.
A linguistics specialist and author, Cecilia loves teaching with the Mamaestra ToyBook to make lessons real and fun. Parents learn Spanish together with their little ones, and teachers use the ToyBook in hands-on lessons.
Every book touches more lives
Our toybooks are handmade by Ecuadorian women. Through this project we want to fund social projects that improve the well-being of women and sponsor more handmade educational products.
Building bridges. Touching lives. That is what Retobilinguismo means to us.
What we believe
With repetition
Practice to master. Small moments, daily practice.
Learn together
Connection comes first. Give your child your attention and a warm voice.
Make it personal
Grow at your own pace. You don't need perfect Spanish.
