Established by Ronnie Rone in 1972, Rone quickly became recognized as a leader in the geotechnical engineering field with Ronnie at the helm and his focus on managing the highly expansive clay soils in the region, with a particular focus on the Las Colinas Urban Center in Irving, Texas. Rone has maintained a focus on control of ground movement as is evidenced throughout the history of the firm, both in our project portfolio, as well as our internal commitment to solving issues related to ground movement.

In 1984, Rone moved from its original location in Arlington, Texas and opened two locations with one in Dallas and one in Fort Worth. Environmental services were added to the core geotechnical and construction materials service lines during the 1990’s. In 1998, Richard and Harold Leigh acquired Rone and Ronnie Rone retired shortly thereafter. With addition of Larry Bracken in 1999 and Mark Gray in 2001, the company ownership was restructured with Richard Leigh, Mark Gray and Larry Bracken becoming the managing partners of the firm.

Through the early 2000’s, Rone experienced significant growth and expanded into central and south Texas with new office locations in Austin and Houston.

In November 2023, Rone expanded its resources and capabilities by joining forces with RMA Companies, a national organization with nearly 1,500 professionals across 40 offices in 15 states. This partnership enhances our ability to offer greater staffing flexibility, broadened technical expertise, and an expanded range of geotechnical services. As part of this larger network, Rone continues to provide the high level of attention and care that our clients have come to expect ensuring the same commitment to quality, responsiveness, and practical solutions that define Rone’s legacy.
