Teresa was born and raised in Arkansas. She graduated from the University of Arkansas at Little Rock where she met her husband, Steve. She worked full-time in the Records and Registration Office at UALR until she became pregnant with their first child, Tyler.
Tyler was born on February 4, 2009, and she became a stay-at-home mom. When Tyler was two and a half years old, he was diagnosed with autism. From that point on, Teresa became his advocate and grew into helping local autism families and creating a local autism support group called Autism Connections. She also worked part-time as a Family Care Navigator at the Dennis Developmental Center at Arkansas Children's Hospital, where she was able to help newly diagnosed families get the resources they needed.
In 2018, tragedy hit her family when their son, Tyler, suddenly passed away from flu complications. To help keep Tyler's legacy alive (he loved helping others), Steve and Teresa established a non-profit organization called the Tyler Dannaway Foundation where she is the Executive Director.
In May 2023, Teresa graduated from the Arkansas Alliance for Disability Advocacy’s Partners in Policymaking Program. This program has helped her become a better advocate for the disability community and made her more interested in politics. She is also on the Arkansas Alliance for Disability Advocacy's 2023-2024 Advocacy Advisory Council.
