By Atascadero News · Fri Feb 06 2026

Walter Ring Nielsen passed away peacefully in his home on January 29, 2026. He was born to Walter Ring Nielsen, Sr., and Alice Flaccus Nielsen in Pittsburgh, Pennsylvania, during World War II on December 16, 1942. Due to the war, he did not meet his father until he was almost two years old.

Walt was raised in Southern California and attended college at the University of Arizona, where he met his wife, Pamela Twist Nielsen. They married on November 27, 1965. They started their family while Walt was teaching junior high science in Las Vegas, Nevada. They spent every summer on a ranch in the Smoky Valley in central Nevada. They hosted many visitors, held 4th of July rodeos, and even ran a boys camp for several years. 

In 1978, they relocated to the Twist Ranch on Creston Road outside of Paso Robles, where Walt was able to be a full-time rancher. The Twist Ranch specialized in registered Red Brangus cattle and also had a vineyard. Walt was honored as SLO’s Cattleman of the Year and later as Agriculturalist of the Year. He particularly enjoyed his work with the Ag in the Classroom committee. 

Walt’s flexible schedule allowed him to be a very involved parent. He never missed his kids’ sporting events and spent many Friday nights cheering on the Bearcats football team. Walt was happiest when he was barbecuing tri-tip with the Cattlemen at the fair or for gatherings of family and friends.

The Twist Ranch was sold in 2013, and after Pam’s death in 2016, Walt retired to Anthem, Arizona, where he enjoyed the warm weather and spent time with his family. He will be remembered as a loving and generous father, a strong advocate for agriculture, and a solid cribbage player. 

He was preceded in death by his parents and in-laws (Basil and Audrey Twist) and his wife, Pam. He is survived by his children, Laura (Rich), Eric (Ellen), and Amber, his grandchildren Ben, Rachel, Nick, and Audrey, as well as two brothers, Robert and David and their families. He will be missed.

No services are currently planned. In lieu of flowers, donations can be made to the SLO County Agricultural Education Committee.
