Dr Aranda Ferrante's academic career took her through some of the country's most respected institutions. She trained in anaesthesiology at USC and Stanford, completed a critical care fellowship at Stanford, and went on to hold assistant professor posts at the University of Pennsylvania across three departments (anaesthesiology, surgery/traumatology and radiology), where she wrote three million dollars in NIH grants. She later served as interim Chief of Anaesthesiology at the Philadelphia Veterans Administration, and as assistant professor at UCLA's Department of Anaesthesiology, alongside a staff physician role at the West Los Angeles VA. In 2002 she was appointed Honorary Professor at Seoul University's Department of Anaesthesiology.

She holds a PhD in Forensic Science and completed a fellowship in age management medicine in Beverly Hills. Since 2018 she has run Aranda MD Enterprises, where her clinical focus has turned to Covid care, post-vaccine injury and cancer recovery, work informed in no small part by her own recovery from a traumatic brain injury and dysautonomia.

Dr Aranda Ferrante is a published author several times over, with titles including Guidebook to Low Back Pain: Diagnosis and Treatment, No More Tears: A Physician-Turned-Patient Inspires Recovery, and the Little Missy Two-Shoes children's series. Her work has featured at events including the American Librarian Association and the World Council for Health's International Covid Summit alongside Dr Robert Malone.

She continues to write and speak widely, including on her Substack publications The Rebel Patient, Renew and Refresh, and Dr Margaret Aranda, where she recently reported on a new legal filing from the Vires Law Group naming Anthony Fauci and others in hospital-related criminal prosecutions across all 50 states.
