Jadd F. Masso


Jadd Masso represents clients from many industries on appeal and frequently joins trial teams to handle procedural or strategic matters, dispositive motions, jury charge issues, and preservation of error at trial.

Clients value Jadd’s experience, big-picture perspective, and ability to distill complex legal issues through oral and written advocacy. Trial lawyers—from both within and outside the firm—regularly call on Jadd to develop creative litigation strategies and to tackle law-intensive issues in court, often accelerating results for clients. A former trial lawyer himself, Jadd’s involvement as appellate counsel at trial results in a seamless transition from trial to appeal.

Like most appellate lawyers, Jadd’s practice covers a wide-range of subject matters, and has included cases involving business and commercial matters, oil and gas, corporate governance, lender liability, real estate, bankruptcy, attorney malpractice, and maritime law.

Jadd is Board Certified in Civil Appellate Law by the Texas Board of Legal Specialization.
