Dr. Doreen DeStefano, DNP, APRN, NHD, is a nationally recognized integrative medicine expert whose work was forged through advanced clinical training and a deeply personal experience. Her father became her “patient zero,” driving her to question conventional assumptions about disease. By combining relentless research, metabolic medicine, and personalized interventions, she helped him navigate cancer in a way that challenged traditional expectations.
Her father is still here today, 7 years later, and that experience became the foundation for Root Causes Holistic Health and Medicine. For over two decades, Dr. DeStefano has helped patients facing cancer, chronic illness, and autoimmune diseases address the true biological root causes driving illness.
Widely known for her groundbreaking “Terrain First, Tumor Second™” philosophy, she focuses on optimizing the body's internal environment. Her work integrates advanced diagnostics with cutting-edge therapies, including metabolic optimization, hyperbaric oxygen, and local regional hyperthermia. A certified practitioner in the Metabolic Approach to Cancer and an instructor for A4M, she is the author of the forthcoming book Biohacking Cancer. Dr. DeStefano remains a trusted voice for patients seeking an innovative, hopeful path forward.
