I've directed creative and brand strategy for major institutions — leading a twelve-person creative team across Cleary Gottlieb Steen & Hamilton's U.S., European, Asian, and South American offices, then serving seven years as Hamilton College's Executive Director of Visual Communication. My work has earned three CASE Gold Circle Awards for campaign and brand system development, and I've taught graphic design at Parsons School of Design and presented at conferences and institutions including Hamilton College and the CASE Editor’s conference.

Since 2023, I've run Mark Mullin Design as an independent consultancy, taking on brand strategy, editorial design, and campaign work for clients including the Miss M Productions (Bette Midler) Asia Society, and John Jay College of Criminal Justice.
