We Fight for You

Sean A McConnell



West Lake Hills, TX





“All of my clients have suffered a tragedy, but none of them ever give up. I channel that bravery and grit and fight hard to get my clients justice.” 

Heart is the word that describes Sean’s approach to his clients’ cases. Sean is sensitive to the personal struggles and inspired by the resilience of those who have been seriously injured or lost a loved one due to negligence. He is compassionate to the challenges his clients face and channels their determination when advocating in the courtroom.

Sean comes to us by way of New York City, where he was born and raised.  He received his JD from Benjamin N. Cardozo School of Law in 2009 and his Bachelor of Arts degree from Catholic University of America in 2006, where he graduated Magna Cum Laude. In law school, Sean was named a Public Interest Fellow and interned at the Manhattan District Attorney’s Office.

After law school, Sean worked for a well-respected New York Supreme Court Judge and then joined a premier plaintiff’s personal injury firm in Manhattan. There, he focused on medical malpractice cases and second-chaired two high profile trials – one of which resulted in one of the largest personal injury verdicts in New York history.

Sean is admitted to the Texas and New York State Bars, and has handled all types of personal injury cases, including medical malpractice, wrongful death, products liability, and car and 18-wheeler truck accidents.  He has recovered substantial settlements and verdicts for his clients.

Sean was named a “Top 40 Under 40” by the National Trial Lawyers Association and has been named a Rising Star by Super Lawyers. Super Lawyers is a rating service of outstanding lawyers from more than 70 practice areas who have attained a high degree of peer recognition and professional achievement. The selection process includes independent research, peer nominations and peer evaluations.  The “rising star” designation is awarded to those under the age of forty.

Outside of the office, Sean enjoys traveling the world with his wife and is an avid fan and player of basketball.
