HB 3509 Missouri House · 2026 Regular Session

Prohibits certain mental health professionals from engaging in conversion therapy with minors

HB 3509 prohibits licensed mental health professionals (such as psychologists and counselors) from performing conversion therapy on minors. The bill defines conversion therapy as any practice seeking to change a minor’s sexual orientation or gender identity, excluding supportive counseling that accepts a minor’s identity or addresses unsafe behaviors without attempting change. This prohibition is added as a specific reason for disciplinary action against license holders under the state’s licensing regulations. The law directly affects minors receiving mental health services and licensed practitioners who may face penalties for violating this provision.
