His arrival at the Ballets de Monte-Carlo set the company on a new path that quickly developed the level of maturity and excellence for which this company of 50 dancers has been renowned for 20 years. He has created almost 40 ballets for the company, some of which, such as Vers un pays sage (1995), Romeo and Juliet (1996), Cinderella (1999) La Belle (2001), Le Songe (2005), Altro Canto (2006), Faust (2007), LAC (2011), CHORE (2013) and Casse-Noisette Compagnie (2013) have forged the reputation of the Ballets de Monte-Carlo across the world. Several of these works are now included in the repertoires of major international ballet companies, such as the Grands Ballets Canadiens, the Royal Swedish Ballet, the Korean National Ballet, the Stuttgart Ballet, the Royal Danish Ballet, the Ballet du Grand Théâtre de Genève, the Pacific Northwest Ballet, the American Ballet Theatre and the Béjart Ballet Lausanne. In 2014, he creates La Mégère Apprivoisée for the Ballet of Bolshoi Theatre.
Also aware of the work of other artists, Jean-Christophe Maillot is known for his spirit of openness and his commitment to inviting choreographers with a different style to create for the company. In 2000, this same desire to present the choreographic art in all its many forms led him to create the Monaco Dance Forum, an international showcase for dance which presents an eclectic proliferation of shows, exhibitions, workshops and conferences.
In 2007, he produced his first stage opera, Faust for the Hessisches Staatstheater and in 2009 Norma for the Monte-Carlo Opera. In 2007, he created his first choreographic film with Cinderella then Le Songe in 2008. In 2009, he developed the content and coordinated the Centenary of the Ballets Russes in Monaco, which would see over 50 companies and choreographers pass through the Principality in one year, providing entertainment for 60,000 audience members. In 2011, dance in Monaco underwent a major and historical change. Under the presidency of H.R.H. the Princess of Hanover, the Ballets de Monte-Carlo now incorporates the Ballets de Monte-Carlo Company, the Monaco Dance Forum and the Princess Grace Academy under a single organisation. Jean-Christophe Maillot was appointed head of this organisation which now unites the excellence of an international company, the benefits of a multi-format festival and the potential of a high-level school.
