Carl Miller’s Gym is in Santa Fe, New Mexico, so I don’t know how practical it would be for you.
If you can get there, it’s great. Carl’s credentials and personal accomplishments are just about as impressive as they come, and he has several USAW-certified coaches at his gym. Shane Miller, his son, handles a lot of the day-to-day coaching and has an extremely good eye for technique; I’ve benefited immmensely from his observations and corrections.
Membership is expensive; you might call them up and try to set up a meeting for a couple sessions to work on technique. Google ‘Carl and Sandra’s Physical Conditioning Center’ for their website.
