She has worked as an EMT in the field, and a nurse in Emergency Department, PACU, Stress Lab, and the Cardiac Cath Lab. She also has taught paramedic and EMT students as a clinical instructor for three decades, and is well-known in southern Florida as an "ECG guru". She insists, however, that she is not THE "ECG Guru" - the site is. This site is made up of all the ECG gurus out there, coming together to help other teachers and students. Dawn has also done pediatric nursing, home health nursing, and medical-legal consulting.
