Attorney John Grinnan
John Grinnan is a trial lawyer who never backs down unless his clients get the best results possible. He came to Arnold & Itkin in 2021 with nearly a decade of experience standing up to the world’s largest companies on behalf of individuals harmed by their negligence. His legal work focuses on wrongful death and catastrophic injuries.
John grew up in Dallas, where he attended Jesuit College Preparatory School. His undergraduate studies took him to Austin to study government at the University of Texas. He then continued his studies at the South Texas College of Law.
While in law school, John developed his passion for trial advocacy while participating in the school’s nationally-ranked moot court program. There, he was privileged to learn from the late Thomas Gerald Treece.
John’s academic performance earned two awards, including one for finishing with the highest grade in the school’s Advanced Products Liability Course. He was also included on the Dean’s List for four consecutive semesters.
John finished law school cum laude in the top 15 percent of his class. His graduating honors included admittance into the Order of the Lytae and an Academic Merit Scholarship.
After being admitted to the State Bar of Texas, John immediately began his trial work. He spent nearly a decade taking on some of the largest companies to make sure they answered for harming regular people. This experience helped make John a great fit at Arnold & Itkin.
When he isn’t working, John can be found with his wife Sarah and his daughter Clare. He also golfs and loves to support his favorite football, basketball, and baseball teams.
