  • Board Certified in Civil Appellate Law by the Texas Board of Legal Specialization


Board Certified in Civil Appellate Law, Amy Maddux is dedicated to serving clients in appeals before the Texas Supreme Court, the Fifth Circuit, and numerous other state and federal courts of appeals. Her appellate practice includes not only traditional appeals, but also mandamus petitions, interlocutory appeals, and amicus briefing. At the trial court level, she has extensive experience in briefing and trial support, particularly relating to summary judgment motions, the jury charge, post-judgment motions, and preservation of error issues.

One of the hallmarks of Shipley Snell attorneys is the broad experience each brings to the table. Not only does Ms. Maddux’s experience include service as a briefing attorney for the Supreme Court of Texas, her trial and appellate career has included such diverse areas of law as commercial disputes, shareholder actions, energy litigation, class actions, personal injury claims, property disputes, toxic torts, insurance issues, and employment law.

Like Mr. Shipley, Ms. Maddux is a former partner in the Houston office of Baker Botts. She has found that working on engaging matters for exceptional clients in a small firm environment enables her to focus more closely on the unique needs of each client and case. And she is able to do what she loves – research, writing, legal analysis, and strategy – in a highly collaborative environment.

With two sets of twins at home and a busy work schedule, Ms. Maddux wishes she had more time to indulge her passion for writing – something other than legal briefs.
