Sharon Kay Hammer Treacy – June 22, 1944 – June 3, 2026
Sharon Kay Hammer Treacy, (aka, SK) passed away peacefully at home on June 3, 2026, surrounded by the love of her family and held in the arms of her devoted husband and daughters.
Born on June 22, 1944, in Austin, Texas, Sharon Kay was the second of three daughters born to Bert and Oneida Hammer. From the very beginning, she was winsome, gentle, and charming—a beloved companion to her older sister and a joy to all who knew her. She graduated from William B. Travis High School in 1962 and briefly attended the University of Texas.
Sharon married, became a dental assistant, and welcomed two daughters, Laura Kay and Janene Lynette Caldwell. In 1974, she and her family moved to Aspen, Colorado. Following the end of her first marriage, Sharon began a partnership with Paul Brian Treacy that would span more than 50 years. Paul was truly the love of her life. The two were married in Maui in 1986 and shared 40 wonderful years of marriage filled with adventure, creativity, and unwavering devotion to one another.
Together, Sharon and Paul owned and operated KIDSPORT, a children’s ski shop in Vail, Colorado, from 1978 until they sold the business in 2012. They embraced life fully, spending their years creating, skiing, windsurfing, traveling, and building a life centered on love and companionship.
Sharon brought joy wherever she went. Her wisdom, creativity, strength, vivacious spirit, and generous heart touched everyone she encountered. She was cherished throughout her community for her kindness, beauty, warmth, and delightful sense of humor. In the words of poet Maya Angelou, “People will forget what you said, people will forget what you did, but people will never forget how you made them feel.” Sharon made everyone feel loved, welcomed, and valued, and she will never be forgotten.
An expert seamstress, Sharon had an extraordinary eye for detail. Even as a teenager, she could transform yards of taffeta and net into elegant formal gowns for herself, her sisters, and her sisters-in-law. With remarkable talent, she could walk through a department store, sketch a garment pattern from memory, and recreate it as wearable art. The beautiful dresses she made provided countless hours of dress-up fun and treasured memories for her daughters and nieces. Sharon Kay also utilized her sewing skills at KIDSPORT, by insuring that children of all shapes had clothing that helped them experience the thrill of their first winter sports adventure and kept them warm, earning the appreciation of countless families.
Throughout her life, Sharon wore many hats to provide for her family. She approached every challenge with determination and confidence, believing she could accomplish anything she set her mind to. That spirit of self-reliance became one of the many gifts she passed on to her daughters. She also had a special way of making family and friends feel loved and valued—whether through heartfelt words, thoughtful handmade gifts, or her beloved homemade cran-apple jam.
Sharon was the crown jewel of her family, and her absence leaves an immeasurable void. She will be missed deeply and remembered always.
Sharon was preceded in death by her parents, Bert Hammer and Oneida Loney Hammer, as well as her cherished mothers-in-law, Francis Treacy and Nettye McGee Caldwell.
She is survived by her loving husband, Paul Brian Treacy of Vail, Colorado; her daughters, Laura Caldwell-Guenzi (m. John Guenzi) of Merino, Colorado, and Janene Caldwell-Witherite (m. Michael Witherite) of Victor, Idaho; and her sisters, Jacqueline Hammer Caldcleugh and Marcia Hammer Patterson, both of Austin, Texas.
She was a proud and devoted grandmother to three grandsons: Brayden Guenzi and Scott Guenzi (m. Jayden Guenzi) of Sterling, Colorado, and Willis Witherite of Victor, Idaho; and one granddaughter, Dylan Kay Witherite of Victor, Idaho, Sharon’s beloved namesake.
She is also survived by her brother-in-law, Hal Caldcleugh, Brian and Stewart Treacy; nephews Bill Patterson; nieces Elizabeth Caldcleugh-Ginsberg and Jennifer Caldcleugh-Anand; as well as many treasured cousins from the Valk, Loney, Reissig, and Hammer families.
A celebration of life will be organized at a later date. We invite all who knew Sharon to share their cherished memories and photographs on her memorial page. The joy she brought to our lives is a gift we can continue to share in her memory.
