On June 25, 1986, Corinne Butler-Williams, with behind the scene assistance from Jay Sapanaro, founded a board comprising of a group of Substance Abuse Treatment and Mental Health Professionals in Philadelphia, Pennsylvania and New Jersey; A Certification Board that is now known as the National Association of Drug and Alcohol Interventionists (N.A.D.A.I.).

N.A.D.A.I. was established to set and certify compliance with standards of conduct and performance of Substance Abuse Treatment, Prevention and Intervention professionals.

NADAI has grown from providing certifications to Substance Abuse Counselors and Clinicians in the Northeast Corridor to providing them nationwide, and now worldwide, with credential holders in Africa, Japan, Bermuda, Puerto Rico, England, Canada, Holland, Germany, and more!

NADAI's Certification Standards are created to assure an acceptable level of competency for those in the field of addiction and/or mental health /family/pastoral counseling. The mission and purpose of N.A.D.A.I. is to protect the public seeking substance abuse treatment, prevention, and intervention services by assessing the competency of each applicant and awarding a credential attesting to a counselor or therapist having met the requirements necessary to practice.

N.A.D.A.I. recognizes the whole person in the credentialing process. Work experience, life experience, and professional training are all taken into consideration in the competency assessment process. NADAI also provides training and seminars to help ensure that NADAI-certified counselors, therapists, technicians, and specialists are kept abreast of the best practices and methodologies available.

Mission Statement: The National Association of Drug and Alcohol Interventionists is committed to the principle of inclusion by honoring the lifelong experience, academic training, and innate abilities of every applicant.

We believe that these attributes are representative of the whole person and are recognized as integral elements of the professional credentialing process.
