About Us

Founded in 1985, JSA Architects was born from a vision to serve the evolving needs of the Permian Basin and the surrounding region. In the wake of the early 1980s oil bust, local institutions such as Ector County Independent School District, the City of Odessa, and Ector County turned to JSA to address their facilities and long-term planning. In those early years, JSA also expanded its reach with projects in religious and healthcare design, laying the groundwork for a diverse portfolio.

As the community grew, so did JSA. Building on a reputation for responsiveness and creativity, the firm became Odessa’s longest-standing generalist architecture practice—one that continues to thrive. Today, JSA serves clients across West Texas, the South Plains, the Panhandle, the Hill Country, and Greater Houston.

Beyond the Blueprint

Designing for communities for four decades.
