Meet Rachael

Rachael Bradshaw graduated from the University of Cincinnati with her MS in Genetic Counseling in 2004. She has been working as a prenatal genetic counselor in St. Louis since her graduation, first at Washington University School of Medicine (WUSM) and later at Saint Louis University School of Medicine. She has served as a senior genetic counselor and Assistant Professor of Pediatrics at Saint Louis University (SLU) since 2012 and an Adjunct Assistant Professor at WUSM since 2019. Rachael has been involved in the development of prenatal telehealth genetic counseling services and implementation of cell-free DNA screening across the hospital system. She has a passion for the field of Fetal Care and Intervention, and currently focuses her clinical work at the St. Louis Fetal Care Institute at SSM Cardinal Glennon Children’s Hospital. In partnership with a colleague, she has twice secured a grant to fund post-mortem genetic testing for families who experience fetal and neonatal losses, providing crucial answers to dozens of families in the area.

Rachael is also passionate about education. At SLU, she teaches medical students, residents, fellows, and attending physicians on a variety of topics related to prenatal genetics, fetal care, and clinical interviewing techniques. Year 1 SLU medical students have rated her in the top 5% of instructors based on overall quality of teaching. It is her ultimate career goal to establish and help lead a genetic counseling graduate training program, and she is thrilled to be serving as Program Director for the Program in Genetic Counseling at Washington University.

Rachael is committed to the issues of diversity, equity, and inclusion. She is also dedicated to addressing racial health disparities. Since 2012 she has served as Co-Leader of the Fetal & Infant Mortality Review through the community organization, Generate Health, which is dedicated to achieving zero racial disparities in infant mortality in the St. Louis region. She served as Executive Coordinator of the St. Louis Pod of 500 Women Scientists from 2016-2019 and remains an active member, working to increase representation of women, and especially women of color, in STEM. She is actively involved with NSGC, ACGC, and AGCPD, serving on many committees for these organizations.

In her spare time, Rachael enjoys living in the heart of the city of St. Louis with her husband and son. She loves to cook with the ingredients her husband, a sustainable gardener, and her chickens provide. She also likes biking, camping, reading, spending time with friends and family, and watching escapist TV.

Erin Linnenbringer, PhD, MS, CGC
Assistant Program Director

Interdisciplinary population health researcher with the heart and mind of a genetic counselor. Runner/baker/reader. Mom of 2 kids. Co-resident with 2 cats.

Meet Erin

Erin’s interest in genetic counseling research took flight while she was a Postbaccalaureate Intramural Research Training Award fellow in the Medical Genetics Branch at the National Human Genome Research Institute. She went on to complete her MS in Genetic Counseling at Northwestern University in 2003 and started her career as a genetic counselor and research project manager for the Risk Evaluation and Education for Alzheimer’s Disease (REVEAL) study at Boston University. While at BU, Erin was involved in the development of their genetic counseling training program, serving as the inaugural coordinator and lead instructor for the Genetic Counseling Research Seminar Series.

Erin’s passion for research lead her to pursue a PhD in Health Behavior and Health Education at the University of Michigan where she continued to work on the REVEAL Study before transitioning to a predoctoral fellowship at the Population Studies Center. As part of this transition, Erin’s research focus shifted to explorations of how racially stratified social environments may “get under the skin” and shape disparities in breast cancer subtypes. While completing her dissertation, Erin received the Richard Janz Memorial Fund Award from the Department of Health Behavior and Health Education and support from the Population Studies Center’s New Initiatives Fund.

Upon completion of her PhD in 2014, Erin joined the faculty of the Division of Public Health Sciences at Washington University School of Medicine. Her research explores the complex interplay among social, behavioral, and genetic factors, and their subsequent implications for population health and health disparities. Erin is also developing new lines of research that will examine the impact of emerging precision medicine & genetic counseling approaches on the health and well-being of medically underserved populations. She is thrilled to serve as Assistant Director and Research Coordinator for the program, and looks forward to involving genetic counseling students in her research. More information about Erin’s research activities can be found on her faculty website.

Erin is an active member of the NSGC having served in leadership positions for regional conferences and national short courses prior to obtaining her PhD. She is currently a member of the Jane Engelberg Memorial Fellowship Advisory Group, which supports the professional development of genetic counselors and students via research grant funding. Reflecting her public health training and clinical interests, Erin is also a member of the Interdisciplinary Association for Population Health Science and the American Association for Cancer Research.  

In her free time, Erin enjoys running in Forest Park, baking cakes (but not cookies!), reading & discussing literary fiction, and in normal times, travelling with her husband and two children.
