At least she is a real professional piano teacher. My kid is learning piano with her. She can find some problem in your kid's performance which other teachers may not be able to find for years. and she knows how to make your kid play beautifully. She is nice and responsible.

Of course, that is just my opinion. I feel that is also some other parents' opinion here. I donot know the teacher is still taking students or not because I think she already has a lots of students.

If she still takes new students, you can try a few times if you want. I donot think you have anything to lose. In the worst case, you kid can learn something from this experience, especially, your kid is at higher piano grad, because she really knows music and how to play piano.

Hope this help you a bit.
