In 1958, founding member Stanley Efron, after completing his military service, joined Bob Rice to form the firm of Rice and Efron. The firm would later become known as Efron & Kittler.
In 1967, founding member Bob Henson, after leaving the Gray Plant Mooty law firm, joined Duke Tully to form Henson & Tully.
In 1976, Henson & Efron was officially founded. The November 1 merger combined Henson & Tully and Efron & Kittler, a seven-person firm with a primary emphasis on litigation and a three-person firm with a principal focus in the corporate and tax law areas, respectively. The merger greatly expanded the expertise and capabilities of the new law firm and provided the firm’s clients with superior service. The firm’s first office was at 1200 Title Insurance Building in downtown Minneapolis; Joseph T. Dixon served as Managing Partner.
In 2002, after years of growth, Henson & Efron expanded its office space into the 18th and 19th floors of the U.S. Bank Plaza Building.
In 2008, in the firm’s third decade, Clark D. Opdahl took over as Managing Partner. The firm continues to focus on delivering smart solutions in its six practice areas: family law; estate, trust and probate; business law; tax; litigation; and real estate.
