Jennifer L. Arbore, CPA
Partner

“In working with not-for-profit organizations and government entities, I have learned that what counts to them is more than just a clean opinion on the audit. Instead it’s about whether they have enough funds at year end to be able to assist another teen mother; provide a scholarship to a student; work to make a home lead-free or even to lower the tax rate within their municipal government. I work with my clients to ensure that what they want to achieve during the year, they will.”
Jen’s practice is focused on conducting and overseeing financial statement and compliance audits of both not-for-profit organizations and governmental entities in the Rochester, Finger Lakes and Southern Tier Regions. She also works with clients on the implementation of accounting standards and on the identification and execution of best practices.
