Leonardo E. Marmol is an artist and architect based in Los Angeles. Marmol received his Bachelor of Architecture with a Minor in Philosophy from California Polytechnic State University in 1987, was elevated to the College of the Fellows of the American Institute of Architects in 2007, and was inducted into the Interior Design Hall of Fame in 2009.

A founding partner of Marmol Radziner, Marmol oversees all aspects of the unique design-build practice offered by the innovative architecture firm. Marmol lectures widely on the topics of modernism and restoration; Marmol also serves on the Board of Trustees of the Palm Springs Art Museum.

As a painter, Marmol explores affect, abstraction, and personal history. Marmol’s first solo show, Los Colores de Assimilation, focused on what he calls his "search for heritage"; as the American-born child of Cuban parents. Since then, his practice has delved deeper into the formal yet gestural modes of expression characteristic of the Abstract Expressionist movement. Working primarily with oil paint and cold wax medium, Marmol’s negotiation of material is vital to his fine art practice, but the search for meaning is paramount.
