After a two-year clerkship with the late Hon. Wallace A. Edwards of the First Circuit Court of Appeal, Joe Mac, to use his preferred informal name, officially began his legal career 39 years ago on June 3, 1985 when he joined Deutsch Kerrigan as an associate in the Firm’s Construction Department.
He had the honor and privilege of learning “how to be a lawyer” under the tutelage of some of New Orlean’s truly great construction lawyers, including the late Ralph L. Kaskell, the late Frederic “Fritz” Bott, the late Charles F. Seeman, Jr., the late Victor Stilwell, as well as his contemporary Terrence L. Brennan, who actually interviewed him for the job in his slave quarter apartment on a Saturday morning. For the first ten years, his practice included all aspects of liability defense for architects, engineers, contractors, and sureties.
From that experience, including his work as an appellate clerk, his practice grew to encompass nearly all of the Firm’s practice areas at the trial and appellate level, including professional liability of attorneys, surveyors, and insurance agents, toxic tort (asbestos and silicosis), insurance coverage defense, products liability, construction defects, and what may be his singular talent and interest, appellate law and practice.
The successful appeal in 2000 in a case he tried with Robert Kerrigan involving the fire at the Fair Grounds Racetrack led to the highlight of his career. The Firm was engaged to appeal a $154 million jury verdict against a French Parent company which included a $120 million punitive damage award. He seized the opportunity to collaborate on the appeal with Marian Mayer Berkett , a true legal legend and brilliant appellate lawyer who was the first woman hired by a Louisiana law firm, Deutsch Kerrigan, in 1937. The collaboration was a proud success. After a six-year legal battle, the judgment was reversed by the Louisiana Supreme Court, completely exonerating the French Company from liability.
He served on the Firm’s Management Committee for ten years. He founded the firm's Diversity Committee and has long championed the importance of creating a workplace where every voice is heard and respected. His dedication to these efforts stems from his personal journey as a pioneer of the Coming Out movement in the 1980s. Joseph firmly believes that fostering a diverse and inclusive workplace is essential for driving innovation, creativity, and success. His leadership in both legal matters and diversity initiatives has been instrumental in shaping Deutsch Kerrigan into a welcoming and forward-thinking community where everyone can thrive.
He has assisted with teaching a course on Legal Aspects of Architecture for the College of Architecture and Design at Tulane University and a seminar on Construction Law at Loyola University Law School. He has served as adjunct professor at Louisiana State University Paul M. Hebert Law Center teaching appellate advocacy.
In his free time, Joe Mac enjoys woodworking, furniture making, home renovating, and walking his dog Paris (named for the Trojan not the city).
