about

Justin Devillier

Director of Culinary/Partner

Chef Justin Devillier is the Chef/Owner of La Petite Grocery in New Orleans and the 2016 James Beard Award winner for Best Chef: South.

Devillier was raised in Dana Point, California, a small beach town in South Orange County. He spent summers fishing for Yellowtail and Albacore tuna, and in the fall and winter he would dive for lobsters just steps from his front door. This bounty of local seafood inspired him to enter the culinary industry, and after working in local restaurants right out of high school he decided to focus all of his time on becoming a chef. In 2003, Devillier moved to New Orleans in search of a vibrant restaurant community. He cooked in the kitchens of Bacco, Stella and Peristyle, where he learned the intricacies of French cuisine from his mentor, Chef Anne Kearny-Sands.

In 2004, Devillier joined the team at La Petite Grocery as a line cook and was promoted to Sous Chef after one year. Following Hurricane Katrina, he helped re-build the restaurant’s infrastructure, and in 2007 was promoted to Executive Chef. A short three years later, Devillier and his wife, Mia, took over ownership of the restaurant, housed in a century-old building with a storied history. At La Petite Grocery, Devillier puts his creative spin on traditional New Orleans cuisine with dishes like Turtle Bolognese, Panéed Rabbit, and Blue Crab Beignets. In 2014, he was awarded “Chef of the Year” by New Orleans Magazine.

In his free time, Devillier is an avid practitioner of Jiu Jitsu, a golfer, fisherman and hunter, and loves spending time at the beach with his wife and three young daughters.

Mia Devillier

Director of Operations/Partner

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.

Joseph Tiedmann

Executive Chef

Joseph Tiedmann grew up in the rural town of Warren, Connecticut, where he helped his family maintain their large vegetable garden and raise animals such as cows, lambs, pigs, chickens, ducks, and geese. It was this exposure to fresh, organic ingredients and life on a working farm that first sparked his interest in the culinary world; however, it wasn’t until college – and his first job at a local pub – that he fell in love with restaurant life. 

After graduating from New England College in Henniker, New Hampshire, Tiedmann visited New Orleans for the first time to volunteer in the aftermath of Hurricane Katrina. In September 2008, he returned to New Orleans to realize his dream of a career in fine dining. He was hired at La Petite Grocery as a line cook and was promoted to Sous Chef in 2012. Over the next seven years, he gained valuable experience, learning how to manage staff, create menus, and maintain food cost and quality; he also assumed the responsibility of executing all private and offsite events. In 2019, Tiedmann accepted the position of Executive Chef of the restaurant, expanding his role to include managing many of the restaurant’s logistics and menu R&D. At La Petite Grocery, Tiedmann strives to provide each guest with a memorable experience. He is proud to work in a restaurant that has grown significantly and crossed many milestones since its opening. 

When he’s not in the kitchen, Tiedmann enjoys seeing live music, reading history and science fiction, and spending time with his wife.
