With over eighteen years of civil litigation experience in state and federal courts, he has handled a wide variety of cases all over the State of Texas before his appointment as Presiding Judge of the 224thDistrict Court of Bexar County by Governor Rick Perry in 2004. Judge Diaz has achieved Martindale-Hubbell's highest Peer Review Rating (AV) for his ethical standards and legal ability and was listed in "The Scene in SA Magazine" Best Lawyers in San Antonio each year from 2007 through 2014.

He is a member of the San Antonio Hispanic Chamber of Commerce.

Judge Diaz attended the University of Virginia for his Bachelor’s Degree in International Relations and Latin American Studies and received both his Master’s Degree in Public Policy and his Juris Doctor from Regent University.
