Have you considered Gray Cook? I think he’s in West Virginia. That’s closer than ATL, but still not very close to NH. Gray Cook isn’t a follower of Kstarr. His approach is different, but his body of work is impressive. .
I am looking for a similar provider here in NC. Have you asked the coaches/owners of your local Crossfit box? That’s what I did and I was pointed to a local chiro who does Active Release Therapy for my knee pain. ART really helped me! Basically, the chiro moved my leg in different positions and inserted his fingers between my muscles to free things up. It wasn’t pleasant, but it really worked.
