Mark J. Sullivan is a New York-based editorial photographer working across fashion, culture and public life. He photographs runway, presentations, backstage, street style, portraits and editorial fashion, with an approach that combines clean composition, close observation and documentary judgment.

His fashion coverage follows the complete visual story—from fittings, hair and makeup, model preparation and backstage production to the runway and presentation. He works discreetly and efficiently in fast-moving environments, creating polished, publication-ready imagery for designers, producers, PR agencies, publications and talent.

Alongside his fashion work, Sullivan maintains ongoing coverage at the United Nations, where he has been credentialed through Zuma Press Wire since 2021. His photography is distributed internationally through Zuma Press Wire, with downstream availability through Reuters Connect, supplying editorial imagery to newsrooms and institutional clients worldwide.

Based in New York City, he is available for assignments and commissions throughout the United States.
