The mission of the 321 Society is to bring together individuals with Down syndrome and young business and community professionals in a collaborative effort to foster leadership, mentorship, and community engagement. Members of the 321 Society will participate in community presentations to promote awareness and advocacy for Down syndrome. Additionally, they will organize two annual events for teens and adults with Down syndrome. Modeled after a junior board, the 321 Society serves as a supportive and dynamic extension of the DSPNT board.​​

Applications are currently closed for the 2025 year.
