Katy, TX Criminal Defense & DWI Attorney Cynthia Guerra
Protecting a client's constitutional rights requires a skilled and experienced attorney with a passion for justice — willing to fight against the entire weight of the state's prosecution team.
Get to know Cynthia Guerra
Cynthia Guerra is an attorney and counselor at law with over three decades of Texas legal experience. Admitted to the State Bar of Texas in 1991, Cynthia practices in both state and federal courts, including admission to the U.S. Court of Appeals for the Fifth Circuit and the U.S. District Court for the Southern District of Texas — federal forums where the stakes and procedural rigor are highest.
Cynthia's practice focuses on criminal defense, DWI, and family law, where her trial preparation and cross-examination skills are her greatest tools. On the family law side, she represents Katy and Houston-area clients through divorce, child custody, child support, and family-related matters — including families navigating the legal complexities that come with owning a small business. She is a member of the Texas Criminal Lawyers Association, the Harris County Criminal Lawyers Association, and the American Association of Premier DUI Attorneys. Her advanced training in cross-examining police officers in DWI cases gives her a specialized edge that often makes the difference in drunk driving prosecutions.
For Katy and Houston-area clients facing criminal charges or family law disputes, Cynthia brings the experience of seeing how cases play out in courtrooms across Harris and Fort Bend County — knowledge that translates directly into smarter motions, sharper cross-examinations, and better outcomes for the people she represents.
