Who We Are

AH is a professional-services firm that specializes in helping non-profit organizations achieve their mission, create value, and advance their causes, industries, and professions. We have four main divisions within AH — a full-service association management company (AMC); a marketing and communications agency; a meetings and events management team; and a division that focuses on other custom solutions, such as strategic planning, website builds, database integrations, accounting, recruitment, public affairs and lobbying, certification management, and growing non-dues revenue.



A young Bill MacMillan watched his father work in the association management industry and, over the years, it kindled the dream of starting his own company. After serving proudly in the U.S. Navy, Bill decided to make his vision a reality, and started AH in a one-bedroom apartment in Moorestown, New Jersey, in 1978.

Things began modestly, with only five employees and a few associations to manage. The Juvenile Products Manufacturers Association (JPMA) and the Pencil Makers Association (PMA) — which eventually merged with the Writing Instrument Manufacturers Association (WIMA) — were among AH’s early client partners. Small and focused, the underdog, AH, started to scrabble together new clients and a growing industry buzz.

The Excitement was Contagious
Bob Waller joined AH in 1987, working closely with Bill and shooting up the ranks to president in 1998. AH expanded its reach with more and more industries, embarking on a period of swift growth. Medical groups, trade associations, certification groups… AH never shied away from bringing its skills to a new challenge.

From 2000 to today, AH has experienced a meteoric rise by adding clients and staff, and outgrowing several office spaces. In 2011, Michael Dwyer, CAE, became the third owner of AH, where he joined Chief Executive Officer, Bill MacMillan and President, Bob Waller. Mike's 20-plus years of expertise in non-profit management is instrumental in AH's continued growth.  

Accredited by the AMC Institute (AMCi), AH stands tall in the field of association and non-profit management, with an expert staff and best practice systems that are uniquely qualified to propel client partners forward toward success. Seasoned with experience, AH has worked with more than 75 non-profit organizations in various industries, has over 190 employees, and now occupies more than 41,000 square feet. The employees chose AH as one of Philadelphia Business Journal’s Best Places to work, and AH is the first Association Management Company (AMC) to be a Certified Customer Service Organization through the Customer Service Institute of America (CSIA).   

Today, AH stays close to its roots, with an emphasis on customer service, innovation, respect, accountability, and social responsibility.
