Many factors compel trustees and plan professionals to rely upon the support of their administrator. Associated Third Party Administrators is able and prepared to comply, adapt, respond, meet and exceed the requirements of a constantly changing industry.

The number of legislative, regulatory and compliance issues are increasing annually and will continue to do so for some time. The investment, banking and benefit provider industries are constantly experiencing changing market conditions. These changes have increased the exposure faced by Trustees and they have created a challenge which increases the importance of having a technically sound, experienced and expert administrator.

The number one priority at ATPA is to build mutually beneficial and proactive partnerships with each of our clients, working closely with Trustees, both Labor and Management, plan professionals, other service providers, and over 500,000 plan participants and their families.

ATPA offers the highest level of service available anywhere. We are known in the industry as having the most knowledgeable staff. Our team and our clients have made us one of the largest administrators in the country. Our goal is to remain the benchmark in employee benefit plan administration.
