About Us



The O’Brien Law Firm was founded in 2006 by Aaron J. O’Brien and Christina M. O’Brien, a husband and wife team. While still partners in life, Christy began working at Henderson Franklin in 2013.


The O’Brien Law Firm is located on the Third Floor of the historic Richard’s Building located at 1617 Hendry Street in Fort Myers. We are centrally located within a short walking distance of the Lee County Justice Center, the Federal Courthouse, City Hall, Lee County Mediation, Lee County Administration and all downtown buildings.


 The O’Brien Law Firm office is open Monday through Friday, with availability on the weekends when necessary. When not in the office, we can be contacted 24/7 through our telephone answering service.




Aaron O’Brien vigorously represents people of all kinds in all kinds of predicaments. He has earned a reputation for a tenacious style and success in the courtroom.


Aaron O’Brien has appeared on Closing Arguments with Nancy Grace (mercifully there was a guest host that day), Both Sides with Vinnie Politan, Catherine Crier Live, Trial Heat, Open Court, Daybreak, the News-Press, Bonita Banner, Naples Daily News, Cape Coral Breeze, and more.


You can be sure that no matter what your circumstances are, Aaron O’Brien will not judge you, but zealously represent you and fight for you. He will spend the time necessary to listen to you, to fully understand you, and to achieve the best possible result for you.


In his off time, Aaron O’Brien trains for, and competes in, marathons and other races. He enjoys time with family, boating, fishing, hiking, biking, hunting, music, reading and advocating for limited government, freedom and liberty.
