About Thomas
Thomas Thomassie built his legal foundation at Louisiana State University in Baton Rouge, earning a J.D. in 2005. He moved into private practice soon after and has spent his career working in Louisiana courts and federal districts across the state. He balances litigation and dispute resolution work, and he has served in both advocate and neutral roles.
He joined Guglielmo, Lopez, Tuttle, Hunter and Jarrell LLP in 2008. That year gave him exposure to firm-based practice and courtroom work. In 2009 he launched his own firm, Thomas Thomassie, LLC. Around the same time he accepted appointments as an arbitrator for the Better Business Bureau. His role there has involved handling consumer and business disputes through the bureau's procedures.
Thomassie is also certified as an Auto Line Arbitrator by the Better Business Bureau. That certification authorizes him to serve on panels that review automobile disputes through established arbitration programs. The certification complements his work as a private practitioner and adds a neutral dispute-resolution credential to his resume.
His admissions cover the state of Louisiana and three federal districts: the Eastern, Western and Middle Districts of Louisiana. Those credentials allow him to file and argue cases in state courts and in federal court across much of the state. He has cultivated a practice that regularly appears before judges and arbitration panels within those jurisdictions.
Office locations for his practice include Lafayette and Opelousas. Those offices serve clients from a mix of urban and rural communities in south Louisiana. He manages files, appears in hearings, and conducts arbitration sessions from those bases.
People who encounter Thomassie in court or at an arbitration panel find a lawyer who has worked in both firm and solo settings. He has moved between representation and neutral roles, adapting to the different demands of advocacy and arbitration. The path from a 2005 law degree to private practice and service as an arbitrator shows a steady, local career in Louisiana law.
He currently practices from offices in Lafayette and Opelousas, handling matters in state and federal courts across Louisiana.
