ISO Vocal Coach (Saint Louis)

Looking for a vocal coach in the Saint Louis area, preferably in-person sessions every 1-2 weeks, I'll drive to you.
I'm an alto looking to open up the higher end of my range (A4-D5 belting especially), control and belting.
I regularly practice on my own and am a vocalist in a band, but I don't have any formal training (that's where you come in).
I can give some samples if needed.
I will also take suggestions if you know a good vocal coach!
