"As a former defense attorney, I have been proud to help level the playing field on behalf of my injured clients. I particularly enjoy working with clients to tell their stories in a way that will resonate will judges and juries. And I am especially proud of serving on a trial team in the 3M litigation, helping injured veterans secure justice against a giant company, 3M, that deceptively marketed defective earplugs to our nation’s armed forces.
