Run as search here for Dr. Ahn. In TOS section, MANY people have had dealings with Ahn.

One, he left UCLA.

Two, there are all sorts of reasons why he would either not do YOUR AME, or, do AMEs anymore at all. Sometimes, docs just want to wean out of the work comp system, and that includes getting out of the AMEs, QMEs.

This may not be personal.

I do hope you have an attorney as this is NOT a do it yourself system in CA. Too many ways of losing it all, and the ins. co.s here are out for BLOOD.
