Our History

Gachassin Law Firm’s success began with its founder, Nicholas Gachassin, Jr. Nick Jr. was born and raised in New Iberia, Louisiana, and graduated from Catholic High. He attended undergraduate studies at the University of Southwestern Louisiana and law school at Tulane University. Upon admission to the Louisiana bar in 1970 and after practicing with a local firm in Lafayette for the first 7 years of his career, Nick Jr. ventured out to develop his own firm.  Initially, Nick Jr.’s practice involved clientele from the oil and gas industry, maritime defense and personal injury. After the oil bust in the 1980’s, Nick Jr. pivoted towards medical malpractice defense and continued to grow the Gachassin Law Firm at a newly constructed office located at 1026 St. John Street in downtown Lafayette, of which he developed. He also served as First Assistant Attorney General for the State of Louisiana from 2004 to 2008 and worked closely with Governor Kathleen Babineaux Blanco in legal and political matters involved in the recovery from Hurricane Katrina.

Nick Jr.’s son, Nicholas Gachassin, III, now the primary partner at Gachassin Law Firm, has been practicing for over 25 years. Nick III also began practicing medical malpractice defense, but his true passion was discovered when obtaining his LL.M. in heath law from Loyola University Chicago School of Law. Nick III’s vision for complementing existing clients’ malpractice needs with regulatory and transactional matters developed the corporate and regulatory practice for the Gachassin Law Firm which has continued to grow through his leadership. This same vision, dedication and expertise landed Nick III with LHC Group, Inc. where he has served as its Executive Vice President and General Counsel since 2019.

In 2020, the Gachassin Law Firm relocated to its current location within Park Towers in Lafayette, Louisiana, and Nick Jr. was honored by the Louisiana Bar Association and Tulane Law School for having practiced law for 50 years. In 2021, Gachassin Law Firm introduced Gary Delahoussaye, Benjamin Gaines and Lanzi Meyers as partners.
