Tiffany was born on March 8, 1980, in Dell Rapids, SD to Jeff and Coleen (Callahan) Sutton. At the time, the family lived in Colman, SD. Growing up in a military family took Tiffany to Oklahoma, Alaska, North Dakota and Wisconsin until she joined the U.S. Air Force, where she met the love of her life, her husband Tom.  They moved to Montana and eventually back to Alaska. They lived in Alaska for over 22 years as she served in the Alaska Air National Guard, reaching the rank of Chief Master Sergeant while assigned to the 176th Medical Group at Joint Base Elmendorf-Richardson, Alaska, completing her Bachelor's Degree in Biology and her Master's Degree in Business Administration. As she stated a great deal of times, her most significant achievement in life was her family, her husband Thomas Gregory, son Brenden (20) and daughter Makenzie (17). Tom and Tiffany retired from the military and the family moved to Flandreau, SD in 2022. She truly loved watching Brenden play basketball and baseball at Dakota Wesleyan University and Makenzie playing softball and cheering at Flandreau High School. Some of her favorite hobbies included traveling, gardening, camping, playing cards, reading, watching movies, crafting and spending time with friends and family.

Tiffany is survived by her husband Thomas Gregory; son, Brenden Gregory; and daughter, Makenzie Gregory of Flandreau, SD; parents, Jeff and Coleen (Callahan) Sutton, Flandreau, SD; and siblings Tyler (Nicole) Sutton, Anchorage, AK and Travis (Rachel) Sutton, Little Chute, WI; and all her nieces and nephews. She was preceded in death by her grandparents, Emmett and Lois Sutton, Flandreau SD and Joe and Patricia Callahan, Colman SD.
