Karen worked in advertising, marketing and promotion from 1973 to present for radio, TV, and newspaper, as well as concert and band promotion. She was a lover of all things music and good vibes. She would be the first one to help out anyone in need and always believed in the good in people. She received the nickname Ma by her friends because she treated them so motherly and lovingly. She never met a stranger and if she did, they immediately became part of her family. She is survived by daughter, Crystal Kletchka and husband Matt of Augusta, KS; son, Charley Horst of El Dorado, KS; grandchildren, Brandon and Dylan Kletchka, and Olivia Horst; sister, Carol Scullawl of Port Orchard, WA; 3 generations of nieces and nephews; a beloved pet, Ms. Kitty; and a multitude of friends.

Because of COVID, a Celebration of Life will take place at a later date.
