It is with heavy hearts that we announce the passing of Karen Hackleman Dahlen, who left this world on October 4^th, 2025, at the age of 84. Our beloved wife, mother, grandmother, great-grandmother, sister, and friend was a beacon of love and strength, whose energy touched everyone fortunate enough to know her.

Born on July 3^rd, 1941, in Mt. Pleasant, UT. Karen was a treasured daughter of Beth Wilcox and Wells Thursby. She grew up with a deep appreciation for family and education. Her boundless curiosity and passion for learning began with Wasatch Academy in Mt. Pleasant. This led her to the Utah Historical Society and to receive a Bachelor of Science, Political Science degree from the University of Utah, as well as her Master of Library Science degree from Oklahoma University (OU), where she cultivated the skills and vision that would guide her throughout her life.

Karen married the love of her life, Roger Dahlen, in May of 1986, and together they built a life filled with work, travel, and devotion. As a mother to two children, Karen was a source of endless love, encouragement and motivation. Her family was her greatest joy, and she took immense pride in their accomplishments and happiness.

Her commitment to many, many charities was a testament to her selfless spirit and desire to make the world a better place.

In her free time, Karen found joy in travelling with family, flowers and yard work. Whether she was planting trees for each of her four grandsons or six great-grandchildren, Karen was always focused on family.
