About Mario A.
Mario A. Olivarez earned his law degree from Texas Tech University School of Law, graduating with a J.D. in 2014. Before law school he completed a Bachelor of Arts in history at Texas A&M University in 2009. Those academic years framed his early legal interests and provided the training he would use back in Texas once he entered practice.
After law school Olivarez began practicing in Texas, the jurisdiction in which he is licensed. He joined local professional organizations soon after, becoming a member of the Costal Bend Criminal Defense Lawyers Association and the Hidalgo County Bar Association in 2015. Those memberships have been a steady part of his professional life and connect him to lawyers across the region.
His work has been anchored in criminal defense. Membership in a criminal defense lawyers association reflects that orientation, and his practice involves representing clients in criminal matters in Texas courts. He handles the sorts of procedural and substantive issues that arise in criminal cases, from pretrial motions to courtroom proceedings. Colleagues describe him as attentive to case details and practitioner-minded in approach.
Olivarez’s background in history shows through in his approach to legal problems. He tends to follow the record closely and to build context around events. That habit can matter in contested criminal matters where timelines, witness statements and documentary evidence shape outcomes. He has continued his professional development through local bar activity and association events since 2015.
Today Olivarez maintains a practice in Texas. He remains active in the Costal Bend Criminal Defense Lawyers Association and the Hidalgo County Bar Association, and he represents clients in criminal cases and related matters across the state.
