T. Coulter McMahen


Coulter McMahen joined Taylor Porter after clerking for Chief Judge S. Maurice Hicks, Jr. of the United States District Court for the Western District of Louisiana. Coulter represents clients across a wide spectrum of industries including public utilities, education, healthcare, insurance and financial institutions.

Coulter’s representative experience includes:


  • Defense of an industrial services company against claims of employee misconduct involving trade secret violations, unfair trade practices, non-compete violations, Computer Fraud and Abuse Act issues, breach of fiduciary duty, and related disputes.
  • Navigating clients through the NCAA infractions process and compliance-related matters.
  • Drafting contracts for coaches and athletic administrators.
  • Representation of banks, financial institutions and other lenders in commercial collection and foreclosure actions, including use of Louisiana’s unique “executory process” procedures.
  • Representing and advising insurers/insureds in tort litigation involving personal injuries, deaths, property damage, insurance coverage disputes, and bad faith. 
  • Representing and advising the State of Louisiana in disputes involving the Louisiana Motion Picture Tax Incentive Act.
  • Multiple successful defenses of premises liability lawsuits at the summary judgment stage.

  • The Miracle League at Cypress Mounds volunteer coach. This nonprofit organization provides children with any type of disability or special needs the opportunity to play baseball as part of team and an organized league.
