Meet our Artists

We work with a select group of exceptional artists whose talent, unique styles, and relentless drive make them a powerful force in the art world. Their work pushes boundaries, delivering pieces that captivate and stand out in any space.

Guillaume Cavalier

Guillaume Cavalier, a self-taught artist born in Nice in 1994, left his studies in 2014 to pursue art in London. Immersed in the city's dynamic art scene, he developed his distinctive style, which led to his first solo exhibition, "L'Homme en Vrac," in 2016. Mentored by Jean Ferrero, he became part of the École de Nice and Nouveau Réalisme movements.

Guillaume's work has been exhibited across France and Europe, with notable shows in Paris, Saint-Tropez, and Barcelona, and in 2020, his paintings reached American audiences in Palm Beach and Beverly Hills. He collaborates with prestigious hotels and galleries, including Le Méridien and Cyril Kamar’s Montreal gallery.

Guillaume’s art, celebrated for its cultural diversity and respect for all forms of creativity, continues to evolve, with upcoming solo exhibitions and new global partnerships.

Rebekah MacKay

Rebekah MacKay is an American abstract artist based in Nice, France, known for creating expansive, layered works that explore paradox through paint, texture, and line. With a B.F.A. in Fine Art from Syracuse University and an M.S. in Photography, she blends innate talent with years of focused study.

Before dedicating herself fully to her art, Rebekah worked in creative services at Ralph Lauren, curating global showroom installations and producing photo campaigns for brands like Prada and Walmart. In 2017, she founded her own creative agency, where she led projects for major clients like Elle France and Jet.com.

Her return to abstract expressionism marks a powerful evolution, with each piece capturing the passage of time and the interplay of chaos and serenity. Rebekah invites viewers to experience the beauty of contradiction, where every canvas unfolds a unique narrative.

John Mejia

John Mejia, a self-taught artist born in 1976 in Cali, Colombia, moved to Paris in 1998, where he immersed himself in the city’s vibrant art scene. Inspired by the Louvre, Musée d'Orsay, and Montmartre’s portrait artists, he developed a unique style that blends Latin passion with French sensuality.

Now based in Mougins, France, Mejia’s work captures the essence of people and places with a distinctive balance of color, atmosphere, and mystery. Influenced by masters like Picasso, Matisse, and Chagall, his art has been exhibited in prestigious galleries and hotels from Cannes to Miami.

In 2016, Mejia gained international recognition for his powerful interpretation of the July 14th attack. In 2024, he presents "Les Grands Maîtres" at the Antibes Art Fair, showcasing his mastery of charcoal and expressive techniques in a new chapter of his artistic journey.
