With Grimshaw since 1996, Juan has played a foundational role in the practice's international expansion and reputation for design excellence, particularly in civic scale projects and the transportation planning and design sector. Based originally in London, Juan helped open the New York studio in 2001 and established the practice's Middle East presence in 2011 before returning to New York.

Juan is passionate about humane design that is both practical and lifts the spirit of its users and the wider community. He believes that such architecture is a result of the purposeful collaboration of architects, engineers, specialists and clients. He has experience across a wide range of building sectors and has demonstrated leadership in realizing creative solutions that exceed client expectations.

Air, rail, mass transit and their associated development has been a focus for Juan since his earliest days at Grimshaw, when he worked on the redevelopment of Paddington Station → in London. He has since applied that expertise to award-winning projects around the world, including the Fulton Street Transit Center →, Grimshaw's first commission in New York City.

Since becoming a partner in 2012, Juan has provided leadership on many significant projects in North America and around the world, including the recently completed tram stops for the Education City Tram Stops → in Qatar and the Metro-North Railroad Enhanced Station Program, comprised of updating the MNRR Design Guidelines and station renovations to White Plains, Harlem-125th St., Crestwood, Port Chester and Riverdale.

Additionally, Juan is currently leading landside development as part of the 2050 Master Plan for John F. Kennedy International Airport → for PANYNJ; concept design for the East Harbour multi-modal transit hub in Toronto; and a family of three signature bridges for Toronto's Port Lands →, accommodating vehicles, trams, pedestrians and cyclists. Previous experience includes the Vaughan Metropolitan Centre Subway Station →, also in Toronto, and the modernization of the Washington D.C. Union Station Concourse →.

Outside of the transportation sector, Juan excels in the design of engaging and sustainable architecture in arts, culture and housing. He was a key designer on the Eden Biomes →, Caixa Galicia Art Foundation → in Spain, Queens Museum → in New York City and the Experimental Media and Performing Arts Center → in Troy, NY.

He was also a designer on the Via Verde → mixed-income housing development in the Bronx and was partner in charge of The Silva →, a luxury multi-family rental building in the historic Meridian Hill district of Washington, D.C.
