"Natural Horsemanship" type clinics in OK, TX, AR

[TBFAN]

Could someone suggest some good, low key, natural horsemanship trainers I could clinic with in this area?
I have an OTTB who had some bad handling before I got him and has been difficult to reform - we did very well riding with Buck Brannaman in 2013 and would like something similar to further our groundwork and basic obedience.

I’m normally an event rider, but this particular horse has responded so well to the things we learned with Buck, that I’d like to do more of it. I just don’t know who is worth trying out. I don’t want to overwhelm him (or me) with the “wrong” kind of NH person.
I’ve got videos and books but I really need some hands on help.

Everyone that has been recommended to me is a full day or two trailer ride away and I was hoping to find some recommendations closer to us. I’m in the Tulsa, OK area but don’t mind trailering 6 hours or less.

Brent Graef out of Canyon, TX is good. Might see if you can find one of his clinics near you.

When you find somebody let me know. I’ve got a green bean I’d like somebody to put some miles on. . . I know buck is coming to Stillwater in February. I’m going to try and audit, but don’t know if I’ll make it.
