Roger was born on August 18, 1935, in Brookings, SD, to Ralph and Mabel Seas. He grew up on the family farm, located nine miles northeast of Brookings. During his younger years, Roger attended Rural School District #13 through the eighth grade before continuing his education at Volga High School. Following high school, he furthered his education by attending night classes at South Dakota State University.

On October 19, 1957, Roger was united in marriage to Beverly J. Ahnberg. Together, they built a life centered around family, hard work, and the many memories they shared throughout the years.

Throughout his working years, Roger dedicated his career to the telecommunications industry, working for two local telephone companies. His commitment to his work reflected the strong work ethic he developed while growing up on the family farm.

Roger was a longtime member of Ascension Lutheran Church in Brookings, where his faith remained an important part of his life. He was also a member of the Elks, Brookings Fire Department and proudly served in the Army National Guard.

Outside of work, Roger enjoyed staying busy with a variety of hobbies and interests. He had a passion for restoring cars and took great pride in bringing older vehicles back to life. This was a passion both Roger and Scott had, spending may hours together on cars. He also enjoyed spending time on the golf course, traveling, and experiencing new places. Above all, Roger cherished the time he spent with his family, creating memories that will be treasured by those who knew and loved him.

Roger is survived by his three children, Tamara G. Seas, Scott A. (Marsha) Seas, and Shawna R. (Tim) Riedemann; four grandchildren, Jacalyn Paradis, Chelsie Seas, Emily Riedemann, and Nick Riedemann; and four great-grandchildren.
