I took her lesson for Callan for Business. Her pronunciation is clear and it would be good for beginners. However, speed and fluency of her speaking are not good enough for intermediate/advanced students. After the reading, she told me that my reading was very fluent but there were some mistakes in pronunciation. She did not tell which words I pronounced incorrectly and did not stop my reading to correct them. Her comment does not help at all if she does not tell which words to be corrected and it just sounded mean at the end of the lesson.
