Madrid. In 2012 they expanded and opened a gallery in London's Mayfair district. Coll and Cortés had already sold works of art to more than 40 museums, including the

Picón, formerly the curator in charge of the Department of Greek and Roman Art at The Metropolitan Museum of Art. In October 2017, Coll and his business partner Nicolas Cortés established the Colnaghi Foundation, a not-for-profit organisation aiming to promote historic art to a 21st-century audience. Coll is on the board of trustees of
The European Fine Art Fair (TEFAF), and also serves on the boards of the International Council of the Wallace Collection, London Art Week and the International Advisory Council of the Hispanic Museum and Library. In 2017, he was listed in 40 Under 40 feature in
