About R. P. Mills Associates, Inc.

​

Trusted Retirement Plan Consultants Since 1961​

R. P. Mills Associates, Inc., is a retirement plan consulting and administration firm based in Schnecksville, Pennsylvania. Founded in 1961 by Robert P. Mills, the firm has more than six decades of experience providing expert Third Party Administration (TPA) services for employer-sponsored retirement plans.

​

Following Mr. Mills’ passing in 1969, the company was acquired by two of his dedicated employees, Charles F. Haggerty and George R. Hood. Officially incorporated in Pennsylvania in 1967, the firm continued to grow under their leadership. In 1988, Charles became the sole owner and led the company until his retirement in 1998, when long-time employees Barry J. Andruscavage and Jan A. Burke took over. In 2017, Barry became the sole owner and continues to lead the firm with a commitment to personalized service and plan compliance.

​

Today, R.P. Mills Associates serves hundreds of businesses and remains a trusted partner in the retirement plan industry. We act as confidential consultants in the design, installation, and ongoing administration of a wide variety of qualified retirement plans.
