While practicing architecture, his penchant for exotic travel and his affinity for eastern cultures often drew him to the Far East, where in 1996 he produced his first collection of handwoven Tibetan rugs made in small ateliers in Nepal. He also launched a collection of hand made tiles for Carocim in Aix-en Provence, his place of birth, based on a hundred-year-old French technique. Then in 2003 while working with a local artisan in Nepal, Colomb began experimenting with Mongolian cashmere, the finest in the world, designing the first of his incredible hand loomed blankets. Soon he discovered new workshops, all the while refining texture, color and technique for a group of exquisite scarves, shawls and wraps.
In 2004, his company Denis Colomb lifestyle was formed with his wife and collaborator, Erica Lennard, the renowned photographer. Four years later their company has grown to include a collection of handknitted sweaters and a full range of knitwear, and is sold in the finest international boutiques around the world. When they are not overseeing the design and production of their collections in Nepal, Denis Colomb and Erica Lennard divide their time between Los Angeles and Aix-en Provence with their cat Neptune.
