Our Staff

STEP has offices strategically located across TN to ensure that families from all 95 counties in TN can be well served including both urban and rural. Of the project staff, seventy-one percent are parents of children with disabilities, while others are family members of a person with a disability, and some staff are individuals with a disability.
