About Us

What makes us great.

Founded in 1972 by four graduates from the University of Tulsa College of Law, Riggs Abney is one of Oklahoma’s largest law firms. Riggs, Abney, Neal & Turpen, merged with the firm Robinson, Lewis, Orbison, Smith and Coyle in 1994 to become Riggs, Abney, Neal, Turpen, Orbison & Lewis. Today, the firm is known simply as Riggs Abney, with offices in Tulsa, Oklahoma City and Denver, providing broad based legal counsel and representation in all aspects of law.

Public Service

At the very core of our ethos is the call to public service. Through the firm, our attorneys and staff are involved in numerous charitable organizations.
