Guests are encouraged to bring a memory of Keith to share at a memory time to be held between 5:30 p.m. and 6:30 p.m. Keith was born on March 10, 1943, in Minot, N.D., to Leroy and Lucille (Allers) Larsen. Keith graduated from Moorhead High School in 1961. He earned a basketball scholarship to Concordia College in Moorhead where he majored in biology.  He was an outstanding basketball player and also ran track where he broke the standing MIAC record time in the high hurdles.  Keith enjoyed his experience at Concordia and proudly wore his Cobber ring throughout his life.  He graduated from Concordia in 1965.  He received his Master of Science degree in educational psychology from Winona State University in 1971.  After graduation, Keith taught science in Kapak, Mich., for a year and then at Lincoln High School in Lake City for three years before choosing a career as a sales rep for Kraft Foods. Through his work, he and his wife Karen enjoyed trips to Hawaii, Hilton Head Island and Puerto Rico. On Aug. 17, 1968, Keith married the love of his life, Karen Kay Brandhorst, and they shared a remarkable 48-year adventure. Left to cherish his memory are his wife, Karen; sisters, Patricia (John) Miller and Mardi (Ronn) Overland; sisters-in-law, Betty Buswell, Marcia (Marcel) Kulas, Sandra (Mark) Bestul, Peggy (Steve) Erwin as well as many nieces, nephews, and extended family.  Keith was preceded in death by his parents, sisters, Joyce Barkus and Detta Nelson, brother, Kenneth, niece, Patty, nephew, David and his parents-in-law, Frederick and Ruth Brandhorst.  Keith loved sparring over politics whether with his daily coffee pals, Dick, Craig, and Jerry, at the YMCA steam room, on the phone with Garon, or with anyone whom he could engage in argument.  He was a lifetime member of the NRA and the Pine Island White Pines Gun Club where he enjoyed trapshooting.  For many years, he enjoyed hunting, fishing, and boating. He always had time for his nephews and nieces who truly loved their Uncle Keith and taught them to catch and clean fish.  A special place in his life was his cabin near Siren, Wis. He especially loved his playdates with his three little buddies, Avery, Leo and Jake. Keith will be dearly missed and remembered as a kindhearted, gentle caring friend to many.  Keith's family thanks the medical personnel and all who cared for Keith at St. Mary's 6B ICU.  Their devoted and kind care was exceptional.  In lieu of flowers, the family requests memorials directed to the Bohris Valley Cemetery, a small country cemetery near Karen's family home where Keith will rest, to Concordia College in Moorhead. or a .
