Sergio es un profesor fantástico. Cada clase era interesante y estaba bien preparada! Estoy muy contenta de poder seguir aprendiendo con Sergio!

Sergio is a fantastic teacher. Very patient and educated person. He is an experienced teacher. He uses a lot of different materials to help me review and practice grammar and develop such skills as conversation and writing. I’m planning to continue my regular classes with him, and will not hesitate to recommend him to any student of Spanish.

Muy contento, me lo recomendó una amiga para tener un mínimo de ingles para mi viaje a Indonesia y me fue genial, super agradecido Sergio.
