Cleo grew up in Sandy, Utah, and graduated from West Jordan High School. Cleo married Harold Arthur “Duke” Sorensen on January 3, 1949, and started a family. She was married to her husband until his passing on February 4, 2003. After her marriage, she lived in Wichita, Kansas; Murray, Utah; Buena Park, California; Midvale Utah, and settled in Las Vegas, Nevada in 1967. Cleo most recently resided with her daughter, K Ann, and her family in North Las Vegas.
Cleo was a housewife, worked as a bookkeeper and held several positions in different retail organizations. As a young woman in Utah, Cleo participated in the Visiting Teacher program organized by the Relief Society of the Church of the Latter-Day Saints. While in Las Vegas, she was a member of the Red Hat Society; a group of ladies that focused on friendship, fun, and freedom while wearing the signature red hat and purple clothing. They had weekly luncheons and enjoyed discussing their families.
Cleo is survived by three of her children; Bradley Harold Sorensen (Brenda), K Ann (Sorensen) Montague (Craig) and Richard Bell Sorensen (Gloria). She is also survived by her grandchildren Monika Cooke (Aaron), Michelle Sharkey, Monte Montague (Heather), Marcus Montague, Michael Minniear (Stephanie), Tonya Hosier (Colby), Tasha Frehner, and Christopher Frehner, as well as her great grandchildren: Ayden Montague, Coleton Cooke, Nolan Cooke, Audrina Montague, Talon Montague, Leela Sharkey, Lucy Sharkey, Michelle Minnier, Alyssa Minnier, Hegan Hosier, Nash Hosier, Nash Hosier, Faith Scolari, and Ty Scolari . She is also survived by her brother-in-law, Robert Sorensen.
Cleo was predeceased by her parents John Thomas Bolliger and Martha Melissa Cundick, her four siblings (Glenden John Bolliger, Noal Wilbur Bolliger, Milo Bolliger and Gene Merlin Bolliger), her husband, and son, Berry Scott Sorensen.
Cleo enjoyed watching college basketball and was a big fan of the UNLV men’s team and the former coach, Jerry “Tark the Shark” Tarkanian. Later, when her vision degraded from macular degeneration, she liked to listen to old black and white movies that were shown on television.
Cleo was feisty, fun loving, big hearted, family oriented, and she enjoyed spending time with her children, grandchildren and great grandchildren. She may have been all of 4’ 9” but she was so feisty she thought she was 6’ 8”. She enjoyed reggae music saying it was “happy music” and enthusiastically danced in the middle of the dance floor to a Bob Marley song during the wedding reception of a granddaughter. She also enjoyed going on rides such as roller coasters and spinning teacups in amusement parks with all her children. If there was a ride that ended with splashing into a pool of water and someone getting soaked, Cleo would be in the front seat with whomever was (un)fortunate enough to ride with her to ensure they got the full experience of the ride. She also floated down the Snake River on an innertube during a camping trip with her family in Idaho, rode an innertube down the side of a snow-covered mountain in Utah along with her family and took a the boat tour of the Chesapeake Bay in Maryland with her husband. Cleo also loved animals. Her house always seemed to have at least one dog and numerous cats. Any stray animal that wandered into the yard became family.
Cleo will always be remembered for her big heart, generous spirit, and devotion to her family. She was always willing to help others and placed the needs of those she loved before her own. Her compassion, kindness and unwavering love touched the lives of everyone fortunate enough to know her.
