In 1985 Osnat began her professional career as a Science Teacher. This field of science includes among others, the human body and its functioning, the subject that interested her very much. In her capacity as a school teacher, Osnat worked not only with regular students, but also with special needs students, including those with ADHD syndrome or children with various of physical difficulties and disabilities. In course of her work, Osnat noticed that body disorganization in many cases resulted in low self-esteem image that had ultimately prevented children from succeeding in their studies and achieving academic degrees. She came to understanding that in order to help older children, one has to start from birth, and she started to look for a field that deals with the sensory-motor development.
After receiving warm recommendations for Dr. Chava Shelhav and her method called Child'Space, she began her studies at the training program at Assaf Harofeh Hospital and in 2011 she graduated as a Child'Space practitioner.
