Deborrah Ann Grieve Best

Deborrah Ann (Grieve) Best was born to parents, Frank and Paula Grieve on February 23, 1966, at Hill Air Force Base in Ogden, Utah. She passed away on December 27, 2024, in Great Falls, Montana due to natural causes.

Debbie was the eldest of three sisters and attended Centerville High School. She was an excellent student, an avid barrel racer, and was active in the color guard. After graduation, she earned an associate’s degree in applied sciences from the Veterinary Technology Program at Eastern Wyoming College and later married Lt. Col. (ret.) Michael Best at the Malmstrom Air Force Base Chapel. She joined him for assignments around the United States and raised her two children, Ryan and Kaleigh. After Mike’s retirement from the Air Force, they returned home to Montana in 2004. The couple divorced in 2012, and Debbie chose to remain in Great Falls, near her family.

Debbie was self-driven, intelligent, and loving. She was a talented artist, cook, baker, and animal lover who enjoyed supporting her family and community with her talents. Unfortunately, despite her family’s unwavering support and efforts to help her with health conditions and mental disorders, she passed away due to complications related to her health and is now at peace.

She is survived by her children, Ryan Best (Gianna Best) of Star, Idaho and Kaleigh Best of Sylva, North Carolina; her parents, Frank and Paula Grieve of Sand Coulee, Montana; sisters, Katherine (Grieve) Campbell of Floweree, Montana, and Cindy (Grieve) Brashear (Shane Brashear) of Drummond, Montana; several nieces and nephews; and two grandchildren.

No funeral service will be offered; however, a private family gathering will be held at a later date. In lieu of flowers, the family is asking for donations to be made in her name to either the National Alliance on Mental Illness or The Brain and Behavior Research Foundation.
