Amanda Gammon is a board-certified genetic counselor with a master’s degree in genetic counseling from University of Colorado at Denver Health Sciences Center. She received her bachelor’s degree from the University of Colorado at Boulder in molecular, cellular, and developmental biology and English literature. While completing her education, Amanda worked at Rocky Mountain Cancer Centers. She began working at Huntsman Cancer Institute in July 2007. She provides genetic counseling regarding hereditary cancer risk to patients in the Family Cancer Assessment Clinic. In 2022, she was promoted to Clinical Lead Genetic Counselor to assist with the implementation of new clinical processes and management of the genetic counseling team.

She has also been involved with cancer genetics research, providing genetic counseling for two National Institutes of Health-funded studies, as well as the High Risk Breast Cancer Clinic (a research site of the international Breast Cancer Family Registries). For the FCARE study, she discussed familial colorectal cancer risk with individuals by telephone in rural Utah and Idaho to assess effectiveness of telephone intervention versus written risk information in encouraging individuals to pursue colonoscopy. For the REACH study, she provided hereditary breast and ovarian cancer counseling to women in rural Utah both by phone and in-person to assess equivalency. Her main research interests include hereditary breast cancer, alternative genetic counseling models/methods, and genetics education.

Amanda is highly involved with genetics education. She served as the Assistant Director for the University of Utah Graduate Program in Genetic Counseling (UUGPGC) from 2016-2019. She continues to teach and provide clinical supervision at Huntsman Cancer Institute for UUGPGC students, as well as serve on the curriculum, research oversight, and clinical supervision committees. She also provides teaching or clinical supervision/shadowing for other medical providers, including fellows and DNP students.
