I’ve had over 10 classes with Guillermo and I plan to continue. He is professional, methodical, organized, and friendly. This is obviously not a side job or hobby for him, it is a job that he takes seriously and is very good at doing. He has a plan for teaching you Spanish and he executes it. Like most things, to get the most out of his classes it is vital that you prepare beforehand and focus. But if you do that he really helps you learn. He’s both a learning partner and facilitator. I highly recommend if you want someone mature, methodical, and professional.

Ich habe bei Guillermo mittlerweile unendlich viel gelernt. Von Vokabular, über Grammatik, bis hin zu Kultur und Geschichte hat er für jede Frage eine Antwort parat. Dank seinem Unterricht fühle ich mich für jede alltägliche Situation bestens vorbereitet.

Guillermo is very popular. And with good reason. He is intelligent, super knowledgable, and writes corrections like no one else. You will be lucky to snag a class with him!

Guillermo continues to be truly exceptional. He is one of the best teachers I’ve ever had in any language. He’s intelligent, engaging, and has a wonderful sense of humor that makes every class both enjoyable and productive. What I appreciate most is his clear, systematic, and well-organized approach to language learning. He has an incredible ability to explain complex grammar and subtle nuances in ways that make them easy to understand and remember. Every lesson feels thoughtfully structured yet natural, and his enthusiasm for teaching is contagious. I’ve learned so much from him and feel lucky to have found such a gifted profesor!

Einfach perfekt, wie immer …

I had an awesome first lesson with Guillermo. He's an excellent conversationalist and provides real time feedback and corrections without interrupting. Definitely looking forward to more.
