The Harrelson Law Firm is a deliniation of Boyd Tackett, the father-in-law of Gene Harrelson and the maternal grandfather of Jeff and Steve Harrelson.  Boyd was a well-known attorney and politician who practiced law all over Texarkana and southwest Arkansas and served in the United States Congress from 1948-1952.  Upon his defeat for the Arkansas governorship in 1952, Tackett began private practice in Texarkana in what would now be known as the Harrelson Law Firm.

Upon Gene Harrelson's graduation from law school in 1969, he joined Tackett, Damon Young, and Nick Patton prior to fulfilling his duties in Vietnam.  At that time, the firm's office was located in the 5th Floor of the State First National Bank Building in downtown Texarkana (now known as the Landmark Building).  The firm moved to the 500 block of Hickory Street in 1970 and added Wayne Dowd and J.O. Moore in 1971.  Marshall Moore was added as a partner upon his graduation from law school, and the firm remained on Hickory Street until Tackett's retirement in 1980, at which time it moved to 1206 State Line Avenue.  In 1987, the firm added Greg Giles as a partner.  Jeff Harrelson joined the firm in 1996, and Steve Harrelson joined the firm in 2002.

The firm was a mainstay on North State Line Avenue -- then known as Dowd, Harrelson, Moore & Giles -- until 2006, when Gene, Jeff, and Steve Harrelson moved into the renovated Foreman Building in downtown Texarkana.  These new offices allow the firm to serve its clients with state of the art facilities and the latest in technology.  The firm is proud to be a part of Texarkana history for more than 50 years.
