To get someone good with the Thompson technique and upper cervical proficiency, is there a particular chiropractic school(s) that I can use for a first cut to decide on who to try? I heard that Life was good for upper cervical. I've had 3 chiropractors in the last year and all three do quick motions on C1 & C2. Usually the upper cervical adjustment doesn't do much for me except give me a headache. (BTW - I have to change again because of insurance changes. My company decreased our insurance quality and the chiropractor I've been going to doesn't want to deal with my insurance company.)
