David Lopez began his legal career in 1988 as an attorney with the San Antonio Community Law Center, a private non-profit legal services organization that he co-founded and that continues to serve working poor families even today. In 1990, Mr. Lopez moved to Los Angeles, California, to work as a litigation associate at Gibson, Dunn & Crutcher, California’s largest law firm. During that time, he worked on various lawsuits, including several major class actions.

In 1992, Mr. Lopez returned to San Antonio to work as a trial lawyer at Davis, Adami & Cedillo. In 1993, he left private practice to join the faculty at St. Mary’s Law School, teaching in the areas of litigation and international law. Between 1993 and 2001, Mr. Lopez was promoted to Professor of Law with tenure, taught over a thousand law students, served as the Law School’s first Associate Dean for Administration, and published various books and articles (including texts on Mexican law and NAFTA). Mr. Lopez also served as a visiting faculty member at the University of California-Davis (1997-1998) and in Baylor Law School’s summer program in Guadalajara, Mexico (1996-2000).

Mr. Lopez returned to law practice in June 2001, initially serving Of Counsel to the law firm of Davis, Cedillo & Mendoza, and then as a partner at the firm from January 2003 until December 2007. During this period, Mr. Lopez worked primarily as a defense lawyer, representing companies, organizations and individuals in complex litigation in Texas and elsewhere. He devoted most of 2007 to representing plaintiffs in a complex dispute involving one of the nation’s largest banks.
