David Carl Nordlund, aged 80, passed away on Sunday, October 1, 2023, in Sioux Falls, South Dakota.

Dave was a highly educated and accomplished individual. Born on July 4, 1943, to Sigurd Carl "Sig" and Helen Augusta (Depner) Nordlund, he was raised in Billings, Montana, and graduated from Billings Central Catholic High in 1961.

Dave continued his education and earned a Bachelor's degree in Physical Education from Eastern Montana College (now known as Montana State University) in Billings. Following college, Dave initially taught biology and coached basketball at Shepherd High School. He then went on to be the principal of Ellesian Elementary School.

After teaching for a few years, Dave enlisted with the United States Marine Corps, where he served his country with distinction and ultimately retired as a Colonel. Dave continued to serve in the Marine Corps Reserve for several years and remained active in the Marine Corps League, assisting other veterans and serving his community.

On December 26, 1966, David married Lana Helgeson in Billings. They resided in Billings and Glendive, MT, and had two children, Heidi and Paul. After 25 years of marriage, Dave and Lana divorced. Later, Dave married Helen Laurente O'Keefe on August 6, 2018.

After serving his country, Dave began his career in communications and was a known expert in the field. He started selling two-way radios in the oil fields, and then, when new technology emerged, he worked in the cell phone industry. He began his career with Motorola, worked his way up to Regional Manager for US West Cellular (Verizon), and later owned and managed several cell phone stores before he retired.

In 1985 Dave and his family moved to Sioux Falls, South Dakota. Dave was an active Marine Corps League Detachment 659 member in Sioux Falls, joined Rolling Thunder Motorcycle Club and was involved in the Dakota Region Porsche Club. Dave enjoyed driving sports cars, fishing with his grandson, and riding his Harley.
