Another great lesson with Arnold! He is an amazing teacher, he is always well prepared for the lesson and is very interactive. He is very patient, easy to talk to, and encouraging, and makes me feel confident to speak in Spanish even when I make mistakes. The lessons are dynamic and fun, and I enjoy how he always keeps me speaking with different questions and topics. I also really appreciate that he takes my interests into account during the lessons and tailors the class to me and my level. He covers the topics that I indicate I want to work on and provides notes of the lesson to explain things and keep track of new vocabulary. He is also really great at explaining grammatical concepts by using visual aids to help me remember! I recommend him to everyone! I will definitely be continuing my studies with him. Thanks Arnold!

Professor Sierra is outstanding. As a retired college professor, I know good teaching when I see it! Professor Sierra is very patient, kind, and professional. I encourage prospective students at any level to take classes with Professor Sierra.

I just love my classes with Arnold, he is such a great teacher. He has a special ability to pull lesson ideas from conversation, and he seems to know when he can push me to try a bit harder. Our classes were always great, but now from having had months of weekly classes with him, his friendship and attitude alows him to push my learning further. Thanks Arnold!
