DeMunbrun Scarnato Associates, Inc. (DSA) celebrates 70 years of providing professional architectural services in the San Antonio and South Texas area. The firm was established in 1953 as a two-man partnership when Bruce Johnson and Charles Dempsey began their architectural practice in San Antonio, Texas. In 1972 the firm was reorganized as Johnson-Dempsey & Associates, Inc. (JDA).

In 1982 Richard Demunbrun merged his firm and became a partner and Senior Vice President of JDA. Tony Scarnato came to JDA as part of the merger and was promoted to Vice President in 1994. In July 1998, JDA began doing business as DeMunbrun Scarnato Associates, Inc. (DSA).

Bruce Johnson passed away in 1988 followed by the death of Charles Dempsey in April 1992. Richard DeMunbrun passed away in December 2018, at which time Tony Scarnato became President of the firm.

We continue to build on the legacy of the firm under the leadership of Tony Scarnato. While we respect our past, DSA continues to expand with many new faces and partnerships. Over these 68 years DSA has built a solid reputation for good design, sound management, and the production of economical projects for our clients, but most of all we have built a reputation for honest dealings with clients, consultants, and contractors.

We approach sustainability as a dynamic evolution that provides synergy between disciplines, not a LEED checklist. Our methodical approach is holistic in nature that delivers greater value at lower cost, improves efficiency, includes a healthy environment for occupants, and reduces operational and maintenance costs, thereby yielding benefits to our clients.

We believe good architecture takes into account all aspects of design, including sustainability. Therefore, we encourage clients to create environments that use simulation analysis for energy, day-lighting, renewable energy and water usage. We use this information to provide a deeper understanding of the metrics and how they affect the life of the building and its users. Our process takes into account the materials and how they are generated and used, thereby fully understanding their true life cycle and carbon footprint.

With over 70 years of service in the architectural field, our firm prides itself on providing exceptional client service, design, and attention to detail from programing through construction administration. Every member of our team is fully committed to a client’s project from conception through completion.
