Erin is proud to call herself a BJH/WashU lifer. Her journey began in 2005 as a night-shift patient care technician in the MICU, and this year, she is celebrating 20 years at BJH, now serving as an assistant professor in the School of Medicine. Over the years, she has held a variety of roles, including patient care technician, ICU nurse, student nurse, and now faculty. She feels incredibly fortunate to have had these opportunities and to work alongside such exceptional colleagues in a remarkable and inspiring department. Along the way, she has built lifelong friendships and connected with many incredible people.
A native St. Louisan and proud resident of the city, Erin can often be seen commuting to work—rain, shine, or cold—on her signature mint-green Vespa. She lives in the Shaw neighborhood with her husband, daughter, two dogs, and a giant African sulcata tortoise. She enjoys spending time outdoors, exploring her vibrant neighborhood, and walking through Tower Grove Park.
Outside of her professional life, Erin stays busy coaching soccer and leading a Girl Scout troop. She has a passion for traveling with friends and family, discovering new restaurants, and staying active at the gym. For her, working at WashU has been a cornerstone of her career, and she couldn’t imagine being anywhere else.
