BerryDunn is a national professional services firm providing assurance, tax, and consulting services to businesses, nonprofits, and government agencies. Founded in 1974 in Portland, Maine, the firm now employs about 800 people working across the United States and serves clients in more than 30 industries.
Its consulting practice covers ERP implementation, financial operations improvement and regulatory compliance, alongside accounting and assurance work. Much of this engagement sits at the intersection of technology and public-sector or regulated environments, where systems implementations must meet audit, financial reporting and compliance requirements. The firm's client base spans healthcare, government and the public sector, and nonprofits.
BerryDunn describes itself as people-first and values-driven, with a stated mission of enabling growth for employees, clients and communities. Many team members are recruited directly from the industries the firm serves, and the company emphasises hands-on expertise combined with outside perspectives. Fifty years after its founding, it operates at national scale while retaining the local, personal character of a regional practice.
