Ann Johnson

Ann Johnson

Ann Johnson grew up in her family's law firm, Johnson Law Firm PC,  started more than 50-years ago,  where co-workers were family, and clients and their families were always welcome.  "We  took folks' cases many others would turn away.  They taught me to listen, work hard and treat others as you would want to be treated. It was always my greatest pleasure to watch my father stand with a client or victim and speak with twelve members of our community to determine what's best." Ann says:  "My passion is the same. During many of my criminal trials, I'd notice my dad would have quietly walked into the courtroom to watch me try the case.  I love being a trial lawyer. "  

Ann continued to expand this family legacy by making history of her own, representing a 13-year old child who had been prosecuted for prostitution before the Texas Supreme Court, successfully arguing for the landmark decision protecting child victims of prostitution and sexual exploitation.        

Ana Martinez
