Cynthia "Cyndi" Clontz was born on March 2, 1942, at St. Anthony's Hospital in Denver, Colorado, to Margaret and Woodrow Cook. She was the oldest of four children-Orville "Butch," Robert "Bob," and Nola-collectively known as the "CORN" kids." She spent her childhood in Denver before her family moved to Evergreen, where she graduated from Evergreen High School in 1960.
On August 8, 1964, Cyndi married the love of her life, James "Don" Clontz. Together they built a life in Arvada and later Westminster, where they raised their two daughters, Danette and Janelle. A devoted homemaker, Cyndi also became a skilled income tax preparer and faithfully helped many families through countless tax seasons.
Family was the center of Cyndi's life, and her love for them was unconditional. Her grandchildren and great-grandchildren brought her endless joy and never failed to make her smile. Family gatherings were filled with laughter, card games, and spirited rounds of the board game Sorry!, creating memories that will be treasured for generations.
Cyndi was a talented and creative woman who spent countless hours sewing beautiful clothing, quilts, and many other handcrafted projects. She also enjoyed crocheting, knitting, chocolate, and was a devoted fan of Elvis Presley. Throughout her life, she cherished many lifelong friendships and looked forward to spending time with friends over lunch. In her later years, she made her home at Covenant Living, where she enjoyed the friendships she formed and the many activities that enriched her days.
Cyndi is survived by her daughter, Janelle (Chris); her granddaughters, Meghan (Charles) and Kylee (Jason); and her grandson, Taylor. She also leaves behind her beloved great-granddaughters, Dakota, Reya, Josie, and Hallie, and her great-grandson, Nathaniel. She is also survived by her brothers, Butch and Bob, her sister, Nola, and loving nephews and nieces.
Cyndi touched countless lives with her kindness, generosity, and unwavering love for her family and friends. She will be deeply missed, lovingly remembered, and forever held in the hearts of those who knew and loved her.
