ABOUT US
We’ve been serving clients since 1973, and although the world outside has changed, our reputation for providing sound accounting advice and services has remained the same—and that’s why our clients return year after year.
From our first office in Wolfeboro, New Hampshire more than 50 years ago, we have steadily grown into a multi-partner firm with offices throughout the state. Our multiple locations give consistent coverage and access for our clients.
In 2014, the American Institute of Certified Public Accountants (AICPA) identified Leone, McDonnell & Roberts, Professional Association as a G400 firm, one of the 500 largest accounting firms in the United States. This is quite an accomplishment. The G400 is a community, connecting similar sized firms, providing a forum to share best practices and supporting firms in facing day‐to‐day and big picture challenges.
At the 2024 Annual Meeting and CPA Inauguration of the New Hampshire Society of Certified Public Accountants (NHSCPA), Leone, McDonnell & Roberts was recognized as Business Firm of the Year, honoring the firm’s leadership and contributions to the accounting profession.
