H3 is a collaborative community of professionals guided by three principals: Ariel Fausto, AIA, LEED AP; John Fontillas, AIA, LEED AP; and Daria Pizzetta, FAIA.  They carry forward the legacy of the firm’s founder and renowned theater architect, Hugh Hardy, who established the predecessor of H3 in 1962. H3's talented team continues to deliver a distinctive and successful approach to planning and design, fostering a dialogue among history, innovation, and contemporary use.
 
Our focus on public building types informs a design approach responsive to context. We honor the cultural heritage of a community, adapting our architecture with each project. Energy-efficient facilities and LEED-accredited professionals confirm our commitment to the built environment, its landscape, sustainability and renewal. Our restrained size permits tailored attention to a select number of clients. We keep our client relationships intentionally one-on-one, and encourage their involvement from a project’s beginning to end. 

In 2017, H3 became the independent Performing Arts, Cultural and Academic Building Studio of Arquitectonica International Corporation benefitting from the firm's global presence and design leadership.
