“We see that the combined DNA of Jackson | Main Architecture will step up creativity along with our goal to be on the leading edge of new design technologies and project delivery systems” said JMA managing partner, Brett Cato


Formed in 2015 by the merger between PKJB Architectural Group and Stricker Cato Murphy Architects, Jackson | Main Architecture brings together two strong lineages stretching back several decades. JMA is located in the recently renovated historic Maud Building in the heart of the Pioneer Square District of downtown Seattle, Washington, with a second location in Kansas City, Missouri. JMA is a mid-sized firm led by principals Brett Cato, Gregg Percich, Robert Kroese, Robin Murphy, Matt Laase, Tim Black, and Darren Orender, with support of associates Katerina Prochaska and Jeff Wasserman, and a staff of fifty. JMA includes licensed architects, intern architects, interior designers, LEED professionals, and a technical and support staff that specialize in multi-family, commercial, mission critical, institutional, retail, single family, and health care design.



JMA provides design services in architecture, master planning, interior design, space planning, and building renovation. We also offer pre-design studies for project feasibility including site evaluations, site utilization and comparative analysis, such as remodel/ renovation versus new construction and reviews for the adaptation of older structures to new and intriguing uses. Collectively, JMA principals are experienced working throughout the United States. JMA inspires with our design, helping our clients succeed by improving people’s interaction with the built environment, emphasizing human needs and responsible stewardship of natural resources.


The evolution of JMA began with the founding of Jean Fraley Architects in 1967. Current partners Robin Murphy and Brett Cato were added in 1991 and 1994 respectively, forming the core of SCMA. Partners Gregg Percich and Robert Kroese opened the doors of PKJB in 1991, starting a successful 25+ year run for the architectural firm founded on an attention to detail and service to their clients. JMA still serves clients who came to the firms over 45 years ago. From Robin Murphy, “We have based our core values on becoming trusted advisors to all of our clients, helping them to build and expand their businesses.” JMA is native to Seattle, with local, regional and national successes in a diverse range of projects.
