History
Founded in 1983 by Jim Stidham, P.E., JSA was initially created to address the growing need for engineering and hydrological services in response to increasing governmental regulations. The firm quickly established itself as a reliable partner for local businesses seeking innovative solutions.
In 2004, Bill Rollins and Rick Kelly acquired ownership of JSA following Jim Stidham’s retirement, further expanding the firm’s reach and capabilities. Under their leadership, the firm grew to include a team of professional engineers, geologists, and water chemistry specialists, as well as an environmental drilling division.
After the retirements of Mr. Rollins and Mr. Kelly, the firm continued to thrive under the leadership of Ben Rush, Scott Sigler, and Anthony Holley. With a forward-thinking approach, they have led JSA into a new era of expansion, broadening the company’s reach nationally and reinforcing its reputation for excellence in engineering and environmental services.
At JSA, we pride ourselves on our commitment to environmental stewardship, technical expertise, and exceptional customer service. Whether you’re a local business or a large industrial client, we’re here to help you navigate the complexities of your engineering projects with precision and professionalism.
