Theresa Caroline Siren, 63, of Rawlins, Wyoming, passed away peacefully on June 9, 2026, surrounded by her loving family. 

     Theresa was born on March 26, 1963, in Rawlins, Wyoming, to Roberta R. James and Wayne C. Siren. She spent her childhood in Rawlins and graduated from Rawlins Senior High in 1981. She later moved with her partner, Kevin Johnson, to Montana, where they spent several years, before she returned to Rawlins. 

     Theresa spent her life building strong connections with her family, friends, and community. It is no surprise she chose to work most of her life in customer service, where she enjoyed meeting new people and sharing conversations with customers from all walks of life. Known for her warm and caring nature, Theresa was the kind of person who would do anything for anyone. She had a remarkable ability to bring a smile to someone’s face, even on their hardest days. Her bright spirit and welcoming personality meant she never met a stranger. She was often described as a wonderful grandmother, a compassionate friend, and an amazing cook whose meals brought everyone together. She especially enjoyed family gatherings, potluck dinners, and spending quality time with those she loved. 

     Theresa was preceded in death by her life partner, Kevin Johnson; brother, Shayne Siren; Stepmother, Linda Siren; and Stepfather, Ron Davis. She is survived by her son, Kobe Johnson (Jasmyn); her grandchildren, Zion and Zenleigh; her mother, Roberta Davis; her father, Wayne C. Siren; her sisters, Julie Davis, Kathy Sanchez, Vickie Haggit, Kimberlee Green, and Rhonda Madden; her brothers, Ken Green, Kelvin Green, and Tyrone Siren, along with numerous beloved cousins, aunts, uncles, and cherished friends. 

     A Celebration of Life will be held at 4:00 p.m., July 22, 2026 at the Depot in Rawlins, Wyoming. In honor of Theresa’s love for gathering with family and friends, a potluck will follow. Theresa’s favorite color was yellow, so please feel free to wear yellow as we celebrate her life.
