Seeking a great vocal/voice teacher

Hello,

I would love any recommendations for an amazing vocal coach/mentor to take my daughter to the next level. She is a accomplished singer and has performed numerous times. She needs a teacher to further train her and help her get where she wants to with her singing. This is for my 12 year old and she does not sing classical music-more musical theater and pop. We live in SF, so any teachers who can commute or live here would be best

thank you so much in advance!
