Diana Sue Rangel-Duncan was born in San Antonio, Texas on December 9, 1953.  She graduated from San Antonio Highlands High School and from St. Mary's University, where she attained a Master's Degree in Counseling. While at St. Mary's, Diana was a member of the Beta Epsilon Lambda sorority, also known as the "belles of St. Mary's." She was married February 14, 2009 to the love of her life, David A. Duncan.

Diana started her professional life in social service with the City of San Antonio Youth Services and she helped found the St. Mary's Church Downtown Youth Drop-In Center serving at-risk youth. She then moved into education where she worked as a classroom teacher and eventually became a counselor. She became a High School counselor at McCollum High School, where she served for over 28 years. In 2012, Diana was inducted into the Harlandale I.S.D Hall of Fame in recognition of her outstanding work with the students, parents, and educators within the Harlandale I.S.D. June 11, 2020, Diana officially retired; however, as recently as the current Fall 2021 Semester, Diana returned to McCollum High School in order to assist a colleague who was out on maternity leave.

Diana was a tireless supporter of youth and her encouragement of countless young people and their families made her well-known in the community. She truly lived her life in service to anyone who was in need and once she helped a person, she often stayed in contact throughout their lives, offering words of support and encouragement.

In numerous Facebook posts, former students of Diana wrote of the tremendous positive impact her guidance had on their lives. Many people credited Diana with their successful graduation from high school, entrance into college, attainment of professional goals, and victory over various personal problems. There was never any judgement in Diana – she truly loved every person she met and she only ever wanted to be loved in return. And loved she was! She could rarely go anywhere in public in San Antonio without running into former students, co-workers, or their families and she had a way of making you feel like you were the most important person in the world to her every time you spoke with her. Her words of encouragement were always powerful because they came from a place of love, empathy, and unconditional acceptance of each and every person she encountered. She truly saw the face of Jesus in every person and they, in turn, saw Christ in her.

Nowhere was this more evident than in the fierce love she showed for her family, especially her nieces, nephews, and Godchildren. Diana was truly a "Super Aunt/Madrina" and she spent a large part of her precious time off attending ball games of all kinds, choir/band concerts, and plays to see her "kids." She enjoyed travel and made numerous road trips. Even when family members no longer lived in San Antonio, Diana made the effort to go and see their games and events. She set the example for the rest of the family with her prayer life, as well! Diana was always the first one to offer to drive to San Juan del Valle or Rockport to make pilgrimages to pray for special intentions or to say thank you for favors and grace received.

Louise Locker, who has led the "Elf Louise Christmas Project" in San Antonio to provide Christmas joy to San Antonio's underprivileged kids since 1969, said that her project has Diana and Diana's parents to thank for helping to get it off the ground in the early days. Louise and Diana were both young college students with jobs and full class loads and together, they made the runs to deliver the donated gifts to children all over San Antonio. Diana's mother Guadalupe took all the phone messages and her father Henry (a SA firefighter) helped find streets, deliver presents, and even played Santa Claus! Louise said the Diana helped plant the seeds of what is now a part of San Antonio's Annual Christmas traditions that has benefitted thousands of local children over the years. She truly walked the walk!

Diana is survived by her beloved husband David A. Duncan, her son Ricky Rangel, her step-daughter Toni White, her step-son Sean Duncan (Lucy); her grandchildren Marisol, Sabrina, Bailey, Rowan, Oran, and Nolan; her brothers Henry (Carol) Rangel, Tony (Cindy) Rangel; her sisters Sr. Rosemary Rangel, RGS, Betty Ann Delgado, and Gloria Salsedo. She is also survived by numerous nieces, nephews and cousins, all of whom will miss her dearly.  Diana was proceeded in death by her parents Henry and Guadalupe Rangel, sister-in-law Rebecca Rangel and brothers–in-law Domingo Delgado and Anthony "Jerry" Salsedo.
