With a professional working relationship spanning three decades, Gary F Martinez FAIA and Thomas E Johnson FAIA founded Martinez+Johnson Architecture in 1994 to bring their design sensitivities to institutional and cultural projects in urban locations. The 25-architect firm has since established an expertise in three main architectural areas – the restoration and adaptive reuse of historic structures, institutional buildings in urban areas and community settings, and the design and planning of performing arts venues.

Known for a thoughtful design approach to public facilities, M+J develops an intimate understanding of the needs of users, patrons, and operators destined to inhabit the projects of the firm. M+J looks to the future in their design aesthetic even when the context may be firmly rooted in the past and executes creative solutions to facilities both new and historic, where flexibility, ease of operation, and high but versatile performance characteristics are requisite. Venues express aspirational values and goals of the communities within which they are located, and at the same time conform to issues of economic value at the highest levels of environmental sustainability.
