Roger Morrison, MD (born 1954), is an American physician and internationally respected teacher of classical homeopathy.
He was born in Rochester, New York, and grew up in Tennessee, USA, where he studied medicine and later worked for several years as an emergency physician.
In 1978 he attended a seminar on homeopathy that profoundly influenced his professional path. Inspired by this experience, he traveled to Greece to study at the Athenian Center for Homeopathic Medicine under the guidance of Prof. George Vithoulkas. Because the program was conducted in Greek, Morrison spent four years learning the language before completing his training.
In 1984 he received his diploma from the Athenian Center and returned to the United States. That same year he helped establish the Hahnemann Medical Clinic and the Hahnemann College of Homeopathy, institutions dedicated to the teaching and clinical practice of classical homeopathy.
Dr. Morrison is widely known as an outstanding practitioner and teacher who communicates complex homeopathic knowledge in a clear and practical way. His books have become standard references for homeopathic practitioners worldwide and have been translated into several languages.
