    I endorse Jose Mata. We worked together on multiple cases in both Oregon and California. His insight, detailed analysis, and reasoning make him a great advocate for his client. While working together, I relied heavily on his advice regarding how and when to use experts in litigation. I have found that Mr. Mata represents his clients well whether in court or in written briefs and highly recommend his services.
