As I said, he must get a lot of work from the WC and personal injury liability insurance companies.

His writing does not meet the Daubert Standard of evidence which is the court standard in Texas. The Daubert Standard is used to prevent 'junk' science from being used in court.

I wonder if this article was published in a peer reviewed journal.

In his CV, I see he was a WC examiner back in 1998-2003.

He appears to be a jack of all trades. They are usually a master of no trades but he does seem to have extensive work with head aches. I do not see any works of a serious nature regarding concussion.

He appears to have double jointed shoulders from patting himself on the back.
