In 1988 during a visit at  a  (residential ) psychologist at the children's home Helper Haven in Groningen, Jimmy was told he received experimental therapy aimed at the life of baby's, when he was between the age of three and four years old (1964-1965).

Jimmy Groen never was allowed to grow up as a normal, real boy during  his childhood. His life turned out to become completely different in many ways. 

At age 27,  Jimmy is photographed with his mother, called Mark (image left)  who became  an  indivisible part of his identity and who never left him

Jimmy11 (image left)  is present from 2004, after Jimmy phinished a pastel portrait of a seven year old boy, becoming his identity. It marked his new name and a new period in life.
