Mr. Ourso has been actively involved in the International Trademark Association for over twenty years and the Intellectual Property Section of the American Bar Association for fifteen years, having served as a chair or vice chair of various committees. See details on his INTA committee work here and his ABA IPL work here.  He was selected in 2013 to the inaugural edition of IP Stars, an international guide to leading IP firms and lawyers published by Managing Intellectual Property, and in each succeeding year through 2016.  In 2016, he was selected by Best Lawyers as the Trademark Lawyer of the Year for Baton Rouge.  He was also selected to Who’s Who Legal:  Trademarks in 2015, the only Louisiana trademark lawyer selected. 

Community Service

For a period of nine years, from the fall of 2002 through the spring of 2011, Mr. Ourso devoted a substantial amount of time to coaching a recreational soccer team with the Baton Rouge Soccer Association, beginning with boys under the age of five.  He coached a total of 33 boys, nine of whom were on the team from five to nine years. All who tried out were selected to a premier team when the team stopped playing. 

Mr. Ourso’s other community service has included serving on the Board of Directors of the South Side Civic Association for three years; as chair or co-chair for the committee at his church responsible for adult retreats and speaking programs for three years; as a solicitor for and as chair of the corporate division of fundraising for the annual giving program for Mary Bird Perkins Cancer Center; as chair of the Parents Annual Giving Campaign for Catholic High School, after serving as a grade level chair for four years; as a major donor solicitor for a capital campaign for St. Joseph’s Academy; a major donor solicitor for Trinity Episcopal School in New Orleans; as a solicitor in two capital campaigns for the University of Virginia School of Law; and on an advisory board for the Literary Circle of Louisiana State University. 


Justin and his wife Ann have reared three daughters and a son through college and to marriage–one is an investment banker in Atlanta, one a managing director of TIAA in Charlotte, one the Congressional Affairs and Public Relations manager for a federal agency in Washington, D. C., and one a Human Resources manager for a software company in New York City.  Justin coached the two youngest in little league baseball and all four on various soccer teams.  Ann worked her magic on the rest of their lives.
