Highly Skilled & Successful Trial Attorney

In over a decade of legal practice, Sergio Ybarra has devoted himself to achieving excellent results for his clients.

As a misdemeanor prosecutor with the Bexar County District Attorney’s Office, Sergio distinguished himself by winning numerous jury trials. He was soon promoted as a felony prosecutor, and eventually found himself assigned to the District Attorney’s DWI Task Force – where Sergio thrived prosecuting felony-level Intoxication Offenses. During his tenure as an Assistant District Attorney, Sergio learned as much as he could about the strategies and methods of the prosecution from the most seasoned mentors possible.

Armed with this knowledge, Sergio entered private practice with the goal of advocating for people who find themselves up against an often-oppressive justice system. With his colleagues at Calfas Law Group, Sergio continues to learn everything he can about the best, and most cutting-edge approaches to the law and trial advocacy.

Sergio believes his purpose in life is to take his clients’ problems off their shoulders, using his skill and experience to guide them through the legal process and achieve the best possible results. By continuing to win jury trials for the Defense, he is pleased to know that every day he makes his purpose a reality. Sergio knows that as long as people need his help, his job will never be finished, and he would not have it any other way.
