Sorry for the long delay in my response to you.
These sort of cases require a high damage factor as well as reasonable certainty of winning because it requires a lot of money to do a medical malpractice case. The expert fees alone that the law firm would have to pay for a case like this can be well over $10,000.00-$50,000.00. This is a hard problem for you to over come, as you really need to have an attorney do the case and you want an attorney who is willing to take the risk.
We cannot directly refer you to a specific attorney. The kind of attorney's you need to look at are of course medical malpractice attorneys. However, you should also broaden your search to include Plaintiff's personal injury
attorneys. Sometimes you can find a firm or lawyer which may not do medical malpractice all the time, but are willing to try your case.
I also suggest contacting the State Bar's lawyer referral service at: http://www.calbar.ca.gov/Public/LawyerReferralServicesLRS.aspx
You can also find local attorneys at www.martindale.com
In the long run, you may need to meet with many different attorneys to find one to take the case. This may be very difficult and take a while, but I encourage you to give it a try.
