Psychosynthesis began in 1910 with the early work of Italian psychiatrist, Roberto Assagioli, M.D. Dr. Assagioli was a colleague of Sigmund Freud, C.G. Jung and Abraham Maslow. Assagioli's work combined methods from Western psychology with spiritually oriented Eastern traditions.  

Edith Stauffer, Ph.D., a student of Assagioli, taught Psychosynthesis at High Point Foundation in Pasadena, CA, from 1965 until 1980. In 1981 she founded Psychosynthesis International so that people in remote or urban areas throughout the world could study and benefit from Psychosynthesis.
