Guillermo is one of the nicest people I have ever met! Though I am at a C2 level in Spanish, I wanted to immerse myself in the unique variety of Spanish (castellano) that is spoken in Argentina. Guillermo has been such a blast to work with in this cultural and linguistic experience! His vast erudition and professionalism consistently exceeds my expectations. Never a dull moment. We can talk incessantly for hours about the vast nuances and clear distinctions that characterize Spanish spoken in Argentina 🇦🇷. I am endlessly enthralled. ¡Muchísimas gracias, Guillermo! ¡Che, sos el mejor!

Guillermo is the epitome of a dedicated teacher! He takes time to plan his lessons and make sure that I learn something new every time. I appreciate how his lessons fuse together language acquisition with cultural education. Gracias un montón!

Every class with Guillermo is a joy. No subject seems off the table — from language and culture to current events and personal insights, his range is incredible. He's a gifted conversationalist: patient, curious, and always generous with his knowledge. I leave every session not only inspired but with new words and expressions that stick with me. Jede Stunde mit Guillermo ist eine Freude. Es gibt kein Thema, das nicht besprochen werden kann – von Sprache und Kultur bis hin zu aktuellen Ereignissen und persönlichen Einsichten. Sein Themenspektrum ist beeindruckend. Er ist ein großartiger Gesprächspartner: geduldig, neugierig und immer großzügig mit seinem Wissen. Nach jeder Klasse bin ich nicht nur inspiriert, sondern nehme auch neue Wörter und Redewendungen mit, die mir im Gedächtnis bleiben.

Znakomity nauczyciel.

I've had several classes with Guillermo, and he is an amazing teacher! My goal was to advance my Spanish more so I could talk about political topics with ease, and each class has been a wealth of information. The little assignments he gives me are so useful, and I learn so much new vocabulary. Mil gracias, Guillermo!!
