Our Chefs

We believe passionately in our teams and the creative minds of our acclaimed and Michelin-starred executive chefs


Executive Chef at The Woodward, Geneva

Originally from Valence, France, Olivier Jean always knew he wanted to become a chef, and it was not without a lot of hard work that the impossible suddenly became possible. Trained among the best, Chef Jean began his career in the kitchens of the celebrated chef Alain Ducasse, first meeting his future mentor at his famed restaurant Le Louis XV in Paris.

Chef Jean joined the Joël Robuchon family in 2010, first at Joël Robuchon Monte-Carlo, then as sous-chef at Atelier de Joël Robuchon Étoile in Paris, and eventually moving to Taiwan to further develop his skills at L’Atelier Taipei, where Chef Jean, at the age of 27, became the youngest executive chef in the history of the Robuchon group.

After more than seven years in Taiwan, and overseeing openings in Montreal and New York, Chef Jean joined The Woodrow Hotel in Geneva as an Executive Chef overseeing L'Atelier de Joël Robuchon and Le Jardinier – both of which will open their doors as the first Swiss addresses for each of these concepts.

Chef Jean has found great success in adapting his native cuisine to the local palate while remaining faithful to the Robuchon brand and philosophy.


Corporate Pastry Chef

A longtime protégé of the legendary Chef Joël Robuchon, Martone serves as Corporate Pastry Chef, overseeing the bakery and dessert programs for all of the restaurants of The Bastion Collection across New York, Houston and Miami. He is behind the Michelin-star winning desserts served at L’Atelier de Joel Robuchon** and Le Jardinier*, and leads creative efforts at our chocolatier Stettler-Castricher.

Prior to joining The Bastion Collection, Martone was the Executive Pastry Chef at the three Michelin starred Joël Robuchon Restaurant and the Michelin starred L’Atelier de Joël Robuchon at the MGM Grand Hotel & Casino in Las Vegas, a position for which he was initially recruited when it first opened in 2005, moving up the ranks from Executive Pastry Sous-chef to Executive Pastry Chef in 2010.

Prior to working in Las Vegas, Martone served as Pastry Chef at the two Michelin starred L’Atelier de Joël Robuchon at the Four Seasons Hotel in New York City. Renowned for his highly creative, whimsical, and delectable plates, Martone’s technical mastery allows him to combine aesthetics and flavor—resulting in desserts that are both visually stunning and delicious. He will often spend months conceptualizing and perfecting a dish, creating custom serviceware and new technique sin order to execute his vision.

A native of Naples, Italy, Martone began his education at the Hotelery School in Naples, Italy, and later attended Instituto Superiore Arti Culinarie in Venice. He came to the United States to pursue his passion for pastry-making and attended the French Pastry School: Art de La Patisserie in Chicago, Illinois, the only culinary school in the country dedicated exclusively to teaching pastry technique. Chef Martone has garnered numerous accolades over the course of his career. He received a James Beard Award nomination for Best Pastry Chef in 2015, was named one of the Top 10 Pastry Chefs in America by Dessert Professionalin 2015, and won the 3rd Annual StarChefs.com International Pastry Competition in 2012.

Renowned for his exquisite and visually striking pastry creations, Martone most recently created and opened Frohzen, an innovative ice cream shop. Frohzen offers unique treats, including our signature ice cream cupcakes, macaron ice cream sandwiches, and cakesicles.


Corporate Executive Chef

With a career spanning more than three decades, Chef Jonathan Benno has worked in some of the world’s finest restaurants and is considered one of the top chefs in the country. As chef and partner for The Bastion Collection, he developed and oversees Leonelli Restaurant & Bar New York, a Roman-inspired trattoria; Leonelli Bakery New York, a bakery and café inspired by the bakeries of Rome; Benno, a fine-dining restaurant serving Mediterranean cuisine; and mostly recently Cafe Leonelli at The Museum of Fine Arts, Houston. Chef Jonathan Benno also serves as a key collaborator for several other concepts of the group. 

Growing up surrounded by farms in rural Connecticut, Benno developed a strong appreciation for food and agriculture from an early age. “My grandmother was the primary cook in the family. She was of Italian descent and taught me respect for ingredients—that they taste best when you pick them yourself. I vividly remember her eggplant parmigiana, especially in the summer when she used eggplant from our garden.”

After high school, Benno enrolled at the Culinary Institute of America in Hyde Park, NY, where he completed an externship at the famed Greenbrier resort in West Virginia. He then worked at the Mayflower Inn and Spa in Washington, CT for the exacting Chef John Farnsworth. “My dad was a carpenter and like a young apprentice looks up to a master, John was a tremendous teacher. He encouraged me to work for great chefs and gave me the push to get out the door,” he recalls.

Upon graduating in 1993, Benno relocated to the Bay Area where he worked under Chef Michael Mina at Aqua, and later moved to Napa Valley to join Chef Thomas Keller at The French Laundry. Chef Keller became an important influence in Benno’s life, helping to shape his philosophy about food and dining, and instilling in him the drive to settle for nothing less than excellence.

Benno then returned home to the East Coast where he gained experience at legendary Chef Daniel Boulud’s eponymous restaurant Daniel in Manhattan; followed by a stretch at the three Michelin-starred Auberge du Vieux Puits in the South of France; and then back to New York as poissonier at Les Celebrites at the Essex House under Chef Christian Delouvrier. Benno then spent two years with Chef Tom Colicchio at Gramercy Tavern, one of which was devoted entirely to pastry. From there, he helped open Craft with Marco Canora. Finally, when Chef Keller was preparing to open his East Coast flagship, Per Se, he recruited his former protégé to serve as Chef de Cuisine.

Benno spent six years at Per Se (2004-2009), overseeing all aspects of the kitchen, and working with Chef Keller to cultivate his distinctive brand of American cuisine and service. Under Benno, Per Se received top marks from the New York Times and three Michelin stars. During this time, Benno was named a StarChefs “Rising Star” (2005), and “Best New Chef” from Food & Wine magazine (2006).

In 2010 when he felt it was time to move on from Per Se, Benno knew he needed to do something completely different if he was going to stay in New York; Italian cuisine was a natural choice. “Since I was a kid I’ve always had a love affair with Italian food, and have traveled to Italy many times over the years.”

Benno went on to open Lincoln Ristorante at New York’s iconic Lincoln Center, where he spent six years as Executive Chef. During this time, he gained acclaim for his contemporary Italian cuisine, including earning a Michelin star, and receiving accolades from notable publications including Esquire, GQ, and the New York Times.

In 2018 the newly redesigned landmark The Evelyn hotel, located in New York’s vibrant NoMad neighborhood, became home to the next chapter in Chef Benno’s culinary epoch. He introduced three distinct, yet complementary concepts: Leonelli Restaurant & Bar, a casual Roman-inspired trattoria; Leonelli Bakery, a bakery and café inspired by the great bakeries of Rome and New York’s rich history of Italian-American pastry shops; and his first eponymous project, Benno, a fine-dining restaurant serving Mediterranean cuisine, which received 3 stars from The New York Times and 1 star from the 2020 and 2021 Michelin Guide. Having assembled expert culinary, beverage, and service teams—many of whom are alumni of Per Se and Lincoln Ristorante—these projects represent the culmination of Chef Benno’s life-long dedication to the hospitality profession which he is excited to continue with his newest endeavor, Cafe Leonelli at The Museum of Fine Arts, Houston.
