He is a great teacher, well educated and the level of his teaching is different, at the academic level mixed with history and literature and other interesting topics.

Ruben is the best Spanish language tutor I’ve had. He is incredibly knowledgeable and educated about many different topics and was brilliant at communicating in an interesting and intellectually stimulating way. Very grateful to learn so much from him.

¡Qué alegría volver a verte!

Ruben is an excellent tutor. He's patient, very informed, and experienced. I'm so glad to have found him. Highly recommended.

Rubén es un profesor muy dedicado y responsable, que se prepara a fondo para cada clase, lo cual es muy gratificante para quienes quieren aprender sobre la historia y la cultura de Bolivia.

Ruben tried hard to teach me. I am just a beginner.
