The Origins of Our Firm


The origins of the law firm of Mossman Law Firm, date back to the 1800s, beginning with the practice of Judge G. M. Gilchrist, Senator W. P. Whipple and Judge E. F. Brown.

Hugh Mossman
(1873-1956) joined the firm of Whipple & Brown in December of 1908 after graduating from the University of Missouri Law School. Hugh served as Benton County Attorney, was a leader in the Republican Party and was widely known as an orator of great skill. He was a cousin to Republican presidential candidate Alfred Mossman Landon. His father, Benjamin Franklin Mossman, had been the Benton County Clerk of Court. Deeply religious and community-minded, he was involved in the Methodist Church and Masonic Lodge for many years and was a director of St. Luke’s Hospital in Cedar Rapids.


Following service in World War II as a Navy pilot, Keith Mossman (1921-2011) graduated from the University of Illinois Law School in 1948.He joined his father, Hugh, in the Vinton practice in June of that year. Keith was elected Benton County Attorney in 1950 and served for 18 years. He was president of the Iowa County Attorneys’ Association and the National District Attorneys’ Association, as well as Chairman of the American Bar Association Judiciary Committee. An orator like his father, he spoke in nearly every state of the union promoting new criminal justice standards. Keith practiced for 62 years before retiring in 2010.


Mark Mossman retired in the fall of 2021 after practicing for over 46 years. He spent his career practicing with both his father and son. Mark went to law school at Drake University after receiving his undergraduate degree from University of Iowa. Mark’s practice focused primarily on estate planning, probate, trust administration, real estate and taxation. Mark continues to support his community and has been involved in several organizations including Virginia Gay Hospital, Vinton Shellsburg School Foundation, Palace Theatre, Vinton Parks and Rec Department.

Our Attorneys are proud to carry on the strong foundation created by Hugh, Keith, and Mark are widely recognized for obtaining the optimal solution for their clients.
