Christofferson, a native of Cache Valley, served in the Army, participating in several campaigns in the Philippines. Long involved in the American Legion, he is the senior member of its National Executive Committee.
He was one of the leading advocates who got the Utah Veterans Memorial Park built in Bluffdale decades ago, and he began working as early as 1966 to get a nursing home built. The 81-bed nursing home adjacent to the George E. Wahlen Veterans Affairs Medical Center was finished in 1998.
Since then, the Utah Department of Veterans Affairs has built a nursing home in Ogden and is finishing two others in Ivins and Spanish Fork.
