Most notably, his careful handling of Titanic: The Artifact Exhibition during his tenure from 1999 to 2009 with Premier Exhibitions led to the successful production of over 100 international and domestic Titanic exhibitions, making Titanic the world’s most popular exhibition with over 25 million visitors worldwide.

A writer and visual artist by training, John transforms the written word into compelling visitor focused imagery that articulates and unifies the central themes of each exhibition. He captures the essence of complex collections, brands, and multi-layered messages, and distills them into clear and comprehensive narratives. Together, John and his hand-picked design team strike a careful balance between nuance and halo moments to conceive memorable and meaningful educational experiences.

John has been the major creative force behind some of the world’s most celebrated and successful exhibitions, including Titanic: The Artifact Exhibition, Bodies: The Exhibition, and Bodies Revealed. More recently, John developed several blockbusters for Imagine Exhibitions and its global partners, such as Jurassic World: The Exhibition, REAL BODIES, Dinosaurs Around the World, Sea Monsters Revealed, and SPY: The Secret World of Espionage.

In addition to playing a major role in the creative development of 12 traveling exhibitions, many of which are currently touring the world, John’s focus on education, experience and messaging inspired the New York Times to label his design work as “genius.” With a deep dedication to the power of storytelling, John delivers immersive and engaging exhibitions for budgets both large and small.

John has also created unparalleled location-based experiences for Bugatti, Volkswagen Group, Manchester United, FIFA and, most recently, St. Louis Union Station, for which he received a Thea Award.
