Since 1920, the American College Health Association (ACHA) has linked college health professionals throughout the nation (and more recently around the globe), forming a powerful, collaborative networking base. This unique synthesis of vision and knowledge, of practice and policy, can guide and support you and your health service, your health programs, and your professional development. ACHA's nearly 3,000 individual and 800 institutional members are why we are "the recognized voice of expertise in college health."
