Need Referral for Personal Injury Defense Attorney

An uninsured worker fell in our home due to their own negligence, and has now retained counsel. Our insurance company is fielding the initial request and we did have both an additional Commercial Liability Policy and an Umbrella policy in addition to our homeowners policy, though we're not sure these will help in CA. We are seeking a top notch personal injury defense attorney in the event our insurance refuses to pay out and he pursues us directly. Thank you in advance.
