I highly recommend Bill Hileman and Kelli Metzger out of Alliance with the Maddogs organization. They've been doing it for a long time and I personally don't think you'll find anyone better. Granted, they're not for everyone - Bill can be tough, but he's excellent and they really care about their girls. There's a 2 hour clinic every Monday starting in October. Prior to that, they may be able to get some individual lessons in, but you would have to contact them for that. My daughter has spent 5 winters there and wouldn't be the fraction of the catcher she is without them.
Billy Dome 9439 Moulin Ave Alliance - though for a while they may be located at Sportzone in Alliance due to renovations on their building.
