ACHS Program Advisory Councils (PACs)

ACHS's close ties with the aromatherapy, herbal medicine, holistic nutrition, and holistic health industries is key to our success and high quality. We want our students and graduates to have a worthwhile experience as a student that then transitions to the workplace. Leaders, educators, and employers in the holistic health and wellness industry have a strong self-interest in helping holistic health education improve and in helping students succeed. Well-trained competent graduates not only are more effective employees, salespeople, and ambassadors, they reduce compliance costs and liability exposure and help advance the industry. 

One of the most effective ways of providing a link between industry and colleges is through the ACHS Program Advisory Councils (PACs). ACHS PACs are essential to successful programs and play an important role in guiding, strengthening, and improving existing programs. Learn more about our Program Advisory Councils online here.
