Dermot Mac Cormack

Before co-founding 21xdesign with his wife Patricia in 1997, Dermot honed his skills in various design studios in Europe and Philadelphia. His passion for communicating visually through design and technology has helped 21xdesign to create lasting relationships with national and international clients. If ever there was a renaissance man this is him. As well as being a consummate designer and illustrator, Dermot has written several books, plays and short stories. He also loves to paint and thrives on music in all its forms. He is also is an avid reader, and pretty much devours books. Oh, and did I mention he is a professor in Graphic & Interactive Design at Tyler School of Art, Temple University, where he is also the chair of the department.

Patricia McElroy

Patricia hates to admit to being a perfectionist, instead, she pours that energy into her work. Her passion for design developed as she grew up in Ireland and Philadelphia. At 21xdesign she brought her experience to bare not only in the artistic side of things but in developing solid client relationships that continue to produce successful and fruitful results. As art director at 21xdesign, her leadership has garnered many awards and recognition for the studio. She also has an insatiable interest in art of many forms. It’s no surprise that she shares Dermot’s interests in the eclectic! Patricia is also a photographer and is seldom without a camera to capture the next image that is always coming her way.
