An intervenor provides one to one support to an individual with sight and hearing impairments caused by congenital Deaf-blindness.

Through various methods the intervenor will encourage the individual to experience the world around them. Some congenitally Deaf-blind people find it difficult to interact with others and their surroundings and so through the use of an intervenor they are able to access experiences with the ultimate aim of broadening their world whilst gaining and developing new skills.

Support is not only limited to the family home. Intervenors can provide access within the workplace, in education or the community.

Usually the intervenor will be a part of a multi-agency team working together to create achievable targets for the individual. These targets are bespoke dependent on what the individual is wanting to achieve or access. An example may be something as simple as maintaining eye contact through to more complex goals such as travel training.

The intervenor can adjust surroundings and environments to them as conducive as possible in matching the needs for both hearing and sight loss but also in terms of achieving goals.

Qualified intervenors have been intensively trained by specialists in the work they do to support Deaf-blind people to access the world around them.
