Kenja Communication, or simply Kenja, is an Australian company co-founded in 1982 by Ken Dyers and his partner, Jan Hamilton. The word 'Kenja' is derived from the first letters of their names. There are four Kenja centres, in Sydney, Greater Western Sydney, Melbourne and Canberra. Kenja Communication runs classes, workshops and one-to-one sessions, as well as events and activities at different venues around Australia. It has gained public attention through court trials involving various members of the group, leader Ken Dyers' suicide following allegations of child sexual abuse, and the group's alleged involvement in the Cornelia Rau case.
