John Hennan loves to advocate. He seeks out clients who deserve dedicated and calculated representation. John began his practice as a trial lawyer in civil and commercial litigation, but now applies his litigation skills to the pursuit of family cases. John has experience in both trial and appellate courts, and has been named a Super Lawyers Rising Star for the last five years in a row. John is also a Certified Mediator in the State of Texas.

John relishes international travel, enjoys reading and studying medieval and renaissance history, listens to all kinds of music (from Iron Maiden to Amy Winehouse), and spends extended periods of time roughhousing with his two dogs, Bruni and Perla. He enjoys being active, working out, running, and playing rugby. John earned his law degree from the University of Texas School of Law, and earned a Master of Laws while studying at University College London.

While John consistently practices all areas of family law, he finds particular purpose in advocating for the following clients and cases:

  • Victims of family violence
  • Tracing separate property interests and developing reimbursement claims between parties’ separate and community estates
  • Jury trials
  • Serving as mediator for parties and attorneys in divorce and custody litigation
