Mattison helps organizations succeed at their mission through focused attention to ensuring every perspective of an organization’s experience is productive by providing leadership, quality events, meetings, programs, and information.
Mattison is an association management firm that specializes in managing non-profit associations. Mattison was founded in 1988 and has experienced modest but steady growth over each of the past twenty four years. We are proud of the work we do, and are happy to assist our clients with carrying out the mission of the associations. Our hard work and desire to carry out the mission of the associations we assist, has resulted in sustainable growth for our clients, built on a foundation of trust and long lasting relationships.

We offer part time services for associations that would normally not be able to afford the cost and overhead of a full time Executive Director or staff. Our staff of nine offers a wide variety of skill sets, that no ONE individual would likely possess. At Mattison, we have the right people doing the right job. We bill our services hourly and typically are more cost effective than hiring an individual Executive Director.
