Diego was born and raised in Spain, where he graduated in Cinematography. Fascinated by photography while working on films and television commercials, he began assisting the leading Spanish photographers of the time. In early 1998 he moved to New York City where he began working with famous fashion and celebrity photographer Tom Munro as his first full-time assistant for over three years. After that time, he began his own independent career.

Almost seven years later, Diego moved to London, where he began building a client list that included: GQ Magazine, Financial Times, Persol, Next, Mister Porter, Hackett, Esquire, Harrods, The Rake, and H&M, to name a few.
