Right off the bat, I found an attorney who might be a good resource. Check out http://www.brandilaw.com/CM/Cases/Co...onworkSite.asp

I have no personal experience or knowledge of this firm. They just came up with a google for concussion and San Francisco. Often, law firms are a good source of physician referrals. I can't tell if they do WComp law.

Here are some MD's who are expert witnesses regarding concussion. They may be good resources too. http://www.hg.org/medical-experts/Me...Concussion.asp

It's a start. Let me know how you do. USSF Medical School may be a good resource too. Medical schools often have interns and residents who are working on special projects that may include your needs.

My best to you.
