Association Headquarters was founded in 1978 and since 2015, the red chair has been a beacon of AH’s unwavering commitment to supporting, achieving, and celebrating the non-profit community. Associations, societies, and credentialing bodies are doing great things to better society and our job is to support them on their journey to greatness, remembering to pause and celebrate when they’ve achieved it, and be with them as they press on confidently to their next success.

The red chair symbolizes our client partners’ seat at the table. It is where they sit while they write their story, make a difference, and advance their mission and cause. Our seat at the table is where we enable them to be their best.

Our clients’ stories are our stories.

We don’t build rockets or cure disease, but we enable those who do. That’s the red chair philosophy.

Our Clients’ Stories are Our Stories.

Where we came from.

Association Headquarters (AH) was founded by Bill MacMillan in 1978 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.
