Since joining HGA in 1997, John has been instrumental to the development of several high-profile, award-winning museum and cultural projects. Recognized for his technical design skills, he is adept at resolving complex programs and researching innovative materials, building systems, and structural solutions. 

With partner Joan Soranno, FAIA, he has established a small in-house design studio within the larger structure of HGA that serves as an incubator for innovative design, producing aesthetically driven, and technically challenging work. Together, they have won four national AIA Architecture Awards, including Marlboro Music Reich Hall Rehearsal Building & Music Library (2023), Walker Art Center Expansion (2021), Lakewood Cemetery Garden Mausoleum (2014), and Bigelow Chapel at United Theological Seminary of the Twin Cities (2006). 

Throughout his career, John also has partnered with other leading international architects, artists, and landscape architects—including Frank Gehry, Herzog & de Meuron, David Chipperfield, James Turrell, and Michel DesVigne and Petra Blaisse—to push the limits of aesthetics, engineering, and technology.
