Agnes Kalthoff

Lifelong Colorado resident, Aggie Kalthoff was born on November 22,1952 in Boulder and passed away in her home in Superior on April 17, 2024. She leaves behind her son, Steve Kalthoff, her daughter, Lora Kalthoff, and her daughter-in-law, Maalikah Hartley.

Aggie was beautiful and bright, and extremely warm and kind to anyone who crossed her path. In her later years she took heart in being with her kids, their animals, and her communities.

Aggie was one of four daughters born to her German mother and Polish father. The Lecinski family had immigrated from Germany after WWII and settled in Nederland, Colorado. Aggie loved documenting her family history, including her father’s remarkable escape from a forced labor camp as a POW. She would also travel back to Germany in her 20’s to visit relatives and enjoy her first Octoberfest.

The Lecinski family moved to Boulder where Aggie would attend Sacred Heart Elementary, followed by Boulder High School class of ‘70. Aggie later attended CU Boulder, where she received her BA in German and Literature and minor in History. Aggie would also acquire a secondary teaching certificate and enjoy working as a German teacher’s assistant for a brief stint of time.

In 1976 Aggie met her husband, Greg Kalthoff, while they were simultaneously working in the same block of Pearl Street and Broadway. Aggie and Greg were adventurers who loved to travel the country, camp, ski, and hike. If you look to the Front Range, almost every peak was summited by the two. Married at the age of 29 in1982 in the mountains of Ward, Colorado, Aggie was wed for 2 years by the time her first child, Steve came along (she initially thought the labor was indigestion from a heavy Thanksgiving dinner). Her daughter Lora would soon follow. Aggie loved to spend time with her family, whether it be downtime at home, skiing in the mountains, or trips to see relatives in California.

Her beloved Greg would suddenly depart just a few years later in 1992. Taking on the role of a single mother of young kids was incredibly difficult, but Aggie managed to do it. She recreated the good times she had with Greg by taking her kids on massive road trips across the country, including most all of the Western states and their beautiful national parks. As her children grew up, Aggie was extremely supportive and proud, and the three remained a close-knit family, up until her final day.

In her adult career, Aggie pivoted to working in technology at StorageTek from 1979 until 2006 where she would also enjoy international travel to places like Japan, Puerto Rico, London, and the Netherlands. After StorageTek, Aggie would go back to school and receive her BS degree in Accounting, where she would specialize in tax work. Aggie then dedicated the rest of her working years at Always Best Care, where she would selflessly help care for elderly patients.

Aggie had a fun sense of humor and was always a treasure to have around! She loved telling stories, food, family get-togethers, holidays, all her fur-baby grandkids, and everything science and science fiction. Her warmth and kindness were palpable, and we are thankful this timeline saw such a loving human being. We remember Aggie as a nurturer, a friend, a mother, a sister, an aunt, and a beautiful soul.
