Originally from Charleston, South Carolina, Mia Devillier is the Director of Operations and co-
owner of La Petite Grocery. Devillier moved to New Orleans in 1996 to attend Loyola University, where she earned a degree in Business Management and Marketing. She began her career in management at Martin Wine Cellar, later returning to the University of New Orleans for a Master’s in Accounting and spending three years as a tax accountant with Deloitte & Touche.

Even while building her professional foundation in business and finance, Mia cultivated her lifelong passion for hospitality, holding positions across the service industry for more than 25 years — including with the House of Blues and restaurants such as Lilette, Juan’s Flying Burrito, and Marigny Brasserie. She joined La Petite Grocery in 2009 as General Manager and, alongside her husband, Chef Justin Devillier, became co-owner in 2010. Under their leadership, La Petite Grocery has earned consistent acclaim, including spots on The Times-Picayune’s “New Orleans’ Top 10 Restaurants” list from 2011–2017, Eater’s list of “38 Best Restaurants in America”, and in 2016 Justin was honored with the James Beard Award for Best Chef: South. Mia’s purpose is to create welcoming spaces where joy, genuine service, and meaningful growth thrive. Guided by integrity, compassion, and attention to detail, she fosters teams and environments that celebrate hospitality while supporting professional opportunity and development.

Outside of her professional work, Mia is blessed with three beautiful daughters, two dogs, and two cats. A dedicated practitioner of Pilates, she finds balance and strength in the same way she approaches hospitality — with intention, discipline, and joy.

Rooted in her Italian heritage, Mia credits her passion for food and wine to her Italian Mother, Cheryle, and late Father, Harley, and her deep sense of Southern hospitality to her late Grandmother, Peggy. In their honor, Mia continues her pursuit of providing memorable dining experiences that bring people together while shaping a culture of hospitality rooted in service, learning, and connection.
