Marmon Mok Architecture is a San Antonio firm founded in 1953 by Harvey V. Marmon Jr. and Edward Mok. It works from offices on Northeast Loop 410 in San Antonio and on East Sixth Street in Austin, offering architecture, interior design and master planning. Its sectors include healthcare and medical education, higher education, K-12 schools, civic and government buildings, sports and recreation, and public assembly. Projects on its site include the Henry B. Gonzalez Convention Center, the Tobin Center for the Performing Arts, University Health’s Women’s and Children’s Hospital, UTSA’s Roadrunner Athletics Center of Excellence and TxDOT’s Stassney campus. At San Antonio International Airport, Marmon Mok designed the ground transportation center, which is under construction and expected to add about 2,500 on-site parking spaces by mid-2027.
One line on the services page is more revealing than any project list: the firm says that designing on sound principles of land use, material use and resource conservation is its goal on every project, regardless of formal certification intent. In other words performance is treated as the default and LEED or similar certification as a client choice – a distinction that matters to public owners who want efficient buildings without paying for the certification process.
The published project set shows how broad a long-established regional practice becomes. Alongside the convention centre and performing arts work, the portfolio includes the Texas Organ Sharing Alliance corporate headquarters, Southwest ISD’s aquatic centre, the Bexar County Public Works Mission Reach office building, the Clarity Child Guidance Center, and the New Braunfels Utilities headquarters, which broke ground recently. A paediatric behavioural health facility, a utility headquarters, a school district aquatic centre and a county public works building are four genuinely different design problems.
Recognition has been running on the interiors side. The firm was named a winner in the 2024 IIDA Healthcare Design Awards, and its people take on industry roles – Meghan Lannom served as a NeoCon juror, and the firm publicised Stephanie De Luna becoming a registered architect, which is the sort of milestone a practice only publishes if growing its own staff is part of how it operates.
The site is structured around work, services, expertise, on-the-boards projects, people, culture, awards and testimonials. The on-the-boards section is worth a look for a prospective client, since it shows current rather than completed work – a better guide to present capacity and staffing than a finished portfolio.
Services are the three a full-service architecture practice needs for institutional clients: architecture, interior design and master planning, with the firm describing design as starting from a sketch or a jotting and ending with something built. Offices are on Northeast Loop 410 in San Antonio and East Sixth Street in Austin, with a front desk contact published for immediate inquiries.
