After receiving a BFA in Painting and Printmaking from the San Francisco Art Institute (he had previously studied Spanish Literature at the University Of Colorado), Martinez acted as one of the Clarion Alley Mural Project directors in SF’s Mission District for nearly a decade.

His paintings have been exhibited in various institutions and galleries, including Syracuse University, Facebook HQ, MACLA(Museo de Arte y Cultura Latino Americana), Mesa Center for the Arts, SomArts, SF Arts Commission Gallery, White Walls, Project1 SF, and 111 Minna.

His work has been featured in the New York Times and other well-respected publications and books. In addition, the artist’s murals grace the walls of many public streets in the US and abroad in major cities, including Oaxaca, Mexico; Zurich, Switzerland; and Florianopolis, Brazil. His murals have been commissioned by Facebook, Tipping Point Foundation, Red Bull, and Climate Works Foundation. SF General Hospital recently commissioned a public piece for its new emergency department through the SF Arts Commission.
