[Highland Park] violin lessons/children's choral groups/orthodontists

Hello Neighbors, I saved up all my querries for one big email. My children aged 5 (almost 6) and 8 are showing a lot of interest in learning an instrument and singing. They actually both have very decent singing voices. I have thought of musical theater but the time and financial committments are too great. Does anyone know of a children's choral group that does not meet after 6:30 pm? Also, suzuki violin lessons or flute lessons. Yes, for some reason they are interested in those instruments. Lastly, recommendations for orthodontists and oral surgeons for the children - we are looking at lots of orthodontia. I'll compile a list of recommendations and post for others. Thank you!
