Colorado's Veterinary Workforce Just Got a Major Change with New VPA Law. On May 30, 2025, Governor Jared Polis signed HB25-1285 into law, officially establishing the role of the Veterinary Professional Associate (VPA). This new mid-level veterinary position is designed to work under the supervision of a licensed veterinarian, with the goal of increasing access to care and addressing workforce challenges. The law takes effect on January 1, 2026.
