Our Story
Built for this community.
By this community.
CORE Foundations was founded by Tony and Sunshine Castaneda, who have spent their careers supporting adults with intellectual and developmental disabilities in this community.
Tony brings 18 years in I/DD services, working his way from Direct Support Professional to Director of Business Operations before founding CORE Foundations. Sunshine brings compassion, program leadership, and an unwavering commitment to dignity in every interaction.
"Every person who walks through our doors deserves support that sees them as a whole human being — not a diagnosis, not a billing code, not a case number."
Together, they built CORE Foundations on two commitments: people first, standards always. We are proud to serve adults with intellectual and developmental disabilities in Topeka and Shawnee County through the HCBS I/DD Waiver.
