I am originally from Germany and have made several attempts to learn Spanish and always found it difficult to find the right approach/teacher/motivation etc. During my first lesson with Sergio, I already felt more comfortable to learn Spanish than before, which was a major reason for me to continue lessons with him. I have finished my first round of ten lessons with Sergio, and just have signed up for another 10 lessons which I look forward to completing and improving my Spanish.
He is extremely easy to understand, goes at a great pace, and is patient. He pushes/motivates you to speak more in Spanish, but without being pushy/placing an uncomfortable amount of pressure. What I really appreciate is that he is always prepared, however not rigid. Although he has a customized agenda for students, he has the ability to adjust when necessary. Due to his experience, he can evaluate your level properly and therefore has a certain flexibility to his teaching style, which I really enjoy and find helpful. I do not think anyone would regret learning Spanish with Sergio. I highly recommend him for all learning styles.
