Where we came from.

Association Headquarters (AH) was founded by Bill MacMillan in a one-bedroom apartment in Moorestown, New Jersey. Bill’s largest client, the Juvenile Products Manufacturers Association, remains a client today, after almost 45 years. AH was built on the vision to be the most innovative and trusted management partner to our client organizations and we have lived that vision with every turn. Each time we adapt to changing landscapes, embark on new endeavors, and experience significant growth, our vision remains clear. AH is proud to be the authoritative voice of association sustainability and growth through experience, education, and foresight. From that one-bedroom apartment to a 40,000-square-foot state-of-the-art office facility, our 170+ staff members are what help AH to remain the most innovative and trusted management partner today.
