André Saine lives and works in Montreal. In 1976, he began studying homeopathy, with teachers including Robin Murphy, Bill Gray, George Vithoulkas, Francisco Eizayaga, and John Bastyr. However, he himself says that he learned the most from the works of the old masters, especially Samuel Hahnemann, Constantin Hering, P.P. Wells, and Adolph Lippe, but also from several others.
André Saine is one of the most sought-after teachers of homeopathy. Anyone who meets him in person can feel that André Saine is a homeopath through and through, with a deep conviction for Hahnemann's method.

Since 1986, André Saine has been teaching philosophy, principles, and materia medica of homeopathy clearly and convincingly at congresses and seminars on the American and European continents. He is a lecturer at the National Center of Homeopathy in Washington, D.C., Dean and senior instructor at the Canadian Academy of Homeopathy in Toronto, Ontario, and President of the Quebec Association of Naturopathic Physicians.

André Saine is an expert on the golden age of North American homeopathy in the 19th and 20th centuries and on the works of Adolph Lippe, whose Collected Writings he is working on. His own publications deal with, among other things, the treatment of severe pathologies and the term „Pure Homoeopathy“ which he coined.

In his large practice in Montreal, Dr. Saine treats almost exclusively severely ill patients with psychiatric illnesses, AIDS, multiple sclerosis, epilepsy, autoimmune diseases, kidney failure, and cancer. He is always striving to expand the scope and possibilities of homeopathy.
