Rock/Metal Vocal coaches in HTX?

As title says, I’m wondering if there are any vocal coaches who specialize in that style of singing because I’ve always wanted to learn and be better at using my diaphragm and just get better at singing. I haven’t found a coach in HTX who does that though and all the vocal coaches I’ve found who specialize in this all do it online 😭. Much help would be appreciated it 🙏
