Lauterbach & Amen, LLP is a public accounting firm based in Naperville, Illinois, founded in 1997 by partners Sherry Lauterbach and Ron Amen. Its emphasis is on quality service, aiming to combine the personal touch typical of smaller firms with the resources of larger practices. Its origins lie in the governmental sector, serving pension funds, municipalities, park districts, libraries, fire districts, and other governmental units. Although government-oriented work remains core, the firm has expanded to include clients outside the public sector while maintaining the same standard of service. In 2026, Lauterbach & Amen announced Addison Township as a new client, following an audit of funds for 2024-2025 that was filed with the DuPage County Clerk.
