Sierra is a good, kind English teacher. Actually, I enjoy every lesson with her. I like her style of teaching because she uses the topics that I choose and prepares materiel for the next lesson. She asks me again or checks if I understand what I learned before. I recognize my improvement after 3 weeks with her. I will continue with Sierra and she makes learning fun
