Recommend a Pitching Coach In Dallas/North Texas

I’m looking for a really good pitching coach for my son (15 years old). We live in Dallas, so I need someone who is in Dallas - or at least in the North Texas region. I’ve kind of lost confidence in the standard pitching coach who sits on a bucket behind home plate and gives advice while he also plays catcher for my son. I’m looking for someone who uses video and other tools to really analyze and improve mechanics.
