Partner, Attorney

Attorney Jason Oxner primarily practices civil law, with a focus on Estate Planning, Business Litigation and Transactions, Probate, and Civil Law.

Attorney Oxner is a Canadian citizen who moved to the United States on an academic and athletic (hockey) scholarship at the Groton School. Jason graduated from Trinity College in Connecticut, following which, Jason attended Thurgood Marshall School of Law where he was an associate editor on Law Review, elected as Mr. Thurgood Marshall School of Law, a Real Property tutor, and graduated Summa Cum Laude in the top 5% of the class. During Jason’s final year of law school, he worked in the school’s prestigious Wills, Probate, and Guardianship Clinic where he assisted low-income members of the community in planning their estates, representing them in probate matters, and representing incapacitated adults in guardianship hearings. After receiving his Juris Doctor, Jason received a scholarship to attend St. John’s University School of Law in New York, where he obtained his LL.M. (Masters of Law).

Prior to cofounding Oxner Legha, PLLC, Jason interned in the Athletic Department at West Virginia University, where he worked directly under the Athletic Director, Oliver Luck, to secure a minor league baseball stadium agreement among other major transactions. Jason then moved back to Texas and began his litigation career in personal injury and business disputes at the prestigious law firm, Abraham Watkins.

Jason has worked for Baylor College of Medicine where he represented doctors and researchers at St. Luke’s Hospital and Texas Children’s Hospital during the negotiation phase of new drugs and devices with private pharmaceutical companies.

Today, Attorney Jason Oxner is a founding partner at Oxner Legha Law Firm in Cypress, Texas where he primarily focuses on Estate Planning and Probate Law. Jason’s clients appreciate his background in business law and property law, which gives him special knowledge on protecting clients’ assets during their lifetime and thereafter.
