Marty Osentowski

May 21, 1963 — July 18, 2020

Marty Kay (Evans) Osentowski was born May 21, 1963 in Rapid City, SD to Marion and Berteen (Trask) Evans. She passed away suddenly July 18, 2020. 

Marty moved to the Sandhills in 1977 and her love for the area kept her here.  She married Gaylen Osentowski on December 2, 1984. On March 17, 1991 they welcomed their son Kolt. 

One would be hard-pressed to think of a time when Marty did not have at least one dog.  She loved her dogs, horses, playing golf, and watching Kolt rope.  She was fiercely competitive in a game of pool or cribbage and spent many evenings challenging friends and family. 

Marty is survived by her husband Gaylen, son and daughter-in-law Kolt and Gina Osentowski, brothers Bill (Barb) Evans and Kelly (Carla) Evans, sisters Becky (Lonnie) Bell, Carol (Ron) Knapp, Jeanny (Lonny) Parmely, and Heather (Jeff) Penner, Numerous nieces, nephews and great nieces and nephews, her dogs Abby, Babe Hazel, and Toots, and a large extended family.

She was preceded in death by her father Marion, mother Berteen, father-in-law Max, mother-in-law Hattie, many good dogs, and a few good horses. 

Marty will always be remembered for living life her own way and for never knowing a stranger.  She will be missed by many. 

The family suggests memorials to the Pelican Beach Golf Club or to a memorial of the donor’s choice.

Memorial Service will be held Friday, July 24, 2020 at 4:00 p.m. MT at the Hyannis Fairgrounds in Hyannis, NE with A.B. Cox officiating. Mullen Funeral Home is in charge of arrangements. An Online guest book may be signed at
