George Vithoulkas is one of the leading practitioners and teachers of homeopathy. He teaches and lives in Greece.

Dr Farokh Master is a rare gem. He has managed to integrate three realms: a traditional, rigorous Hahnemannian approach to prescribing; a deep knowledge of pathology and biological science; and cutting edge insights into the human psyche and disease causation. Dr Master is not a "homeopathic guru." He humbly deals with real pathologies and gets real results.  - Dr Asa Hershoff
