Our Team

The goal of Lango San Francisco is to bring quality classes, which foster academic excellence to parents throughout San Francisco. Our classes are held during the week and weekends at convenient locations. At our classes we ensure that your children will have fun while learning a foreign language. What truly makes our classes successful, however, is most definitely our devoted and tireless teachers. Lango's teachers make our classes truly exceptional. In our selection process, we look for five distinct qualities: native/bilingual fluency, limitless positive energy, creativity, teaching experience with relevant age groups and finally, outstanding communication skills with both children and their parents. Beyond these qualities, though, our teachers bring unique cultural perspectives and professional backgrounds that enable them to create rich, engaging experiences in the classroom.

Born and raised in Mexico City, Ana holds a BA in Communications and Public Relations, with seven years of experience in Marketing, Advertising, and Public Relations. Ana moved to the US in February 2006. Since then, she has been teaching Spanish to kids in private and public settings, where she's well known for the enormous creativity, energy, and enthusiasm she brings to her classes. Ana believes that every child deserves the opportunity to learn a second language, which instills self-confidence, helps develop valuable social skills, and cultivates an understanding and deep appreciation for other cultures and people the world over. Working at Lango has been a most enriching life experience. The Lango Method has given her the opportunity to expose children to different languages, to not only teach them but bring them together. Our success is measured by the success of our children.
