Bolivia has been tutoring me for years and she is an excellent teacher! My Spanish has improved greatly, as she always has relevant examples, and is very patient with me. I have workbooks that I use, and she supplements those with appropriate materials for my level. Bolivia has an excellent command of the English language, which is very useful when trying to explain subtle differences and nuances in meaning. And she is very friendly and fun to work with - we even met up once in Mexico for a casual class at the bar, when we both happened to be in the same city! Muchas Gracias!
