This resource offers a comprehensive introduction to Support Service Providers (SSPs)—specially trained individuals who provide essential access to the environment for people who are DeafBlind. Working at the direction of the DeafBlind individual, SSPs use a range of communication strategies and guiding techniques determined by the person they support. With this access, DeafBlind individuals can actively participate in daily life, including social events, shopping, errands, recreational activities, and more. The resource outlines the key roles and responsibilities of SSPs, explains the difference between Agency SSPs and Personal SSPs, and offers guidance on how to advocate for SSP services to promote independence, inclusion, and self-determination.
