Ann Weiser Cornell (born Ann Weiser on October 6, 1949) is an American author, educator, and worldwide authority on Focusing, the self-inquiry psychotherapeutic technique developed by Eugene Gendlin.

[4] Ann Weiser Cornell received a PhD in Linguistics in 1975 at the University of Chicago, on a Woodrow Wilson Fellowship from the National Science Foundation.

[5] While still a graduate student at the University of Chicago, in 1972 she met psychologist Eugene Gendlin, and learned the psychotherapeutic technique he had discovered and developed, called Focusing.

In the early 1990s Cornell also began developing and teaching processes that emphasized the radical acceptance and allowance of all aspects, however negative, of the personality – and the ability to be present with whatever negativity comes up during Focusing – in order to return to a place of wholeness.

[1][12][13] In the early 2000s Cornell and McGavin also developed a theory and process called Treasure Maps to the Soul, an application of Focusing to difficult areas of life,[1] which they detailed in the book The Radical Acceptance of Everything (2005) along with Inner Relationship Focusing.
