Mark A. Colella is a Certified Public Accountant and the principal of Colella CPA Co., P.C. He works with owner-operated New York businesses — restaurants and bars, professional practices, closely held companies, and newer ventures finding their financial footing.
The firm was built around a straightforward observation: most business owners are not short on financial paperwork. They are short on someone who sees all of it, keeps it current, and tells them what it means before the moment to act has passed.
That is why the relationship is structured as one engagement rather than a series of separate services. Bookkeeping, payroll coordination, filings, and planning inform each other. When they sit with the same CPA, the advice is grounded in what the books actually show.
Clients describe the working style as responsive and direct. Questions get answered. Positions get explained. Nothing important is left waiting for tax season.
Before launch
Mark’s licensing jurisdiction and license number, year the firm was founded, professional memberships, education, and years of experience are held for verification and will be published here once confirmed. No credential, award, affiliation, or statistic appears on this site unverified.
Working style
How the relationship is run.
Direct access
You speak with the CPA handling your work. There is no layer between the owner and the person who understands the file.
Plain language
Tax positions and financial results are explained in terms of what they mean for the business, not in the language of a return.
Current information
The value of a monthly close is that it happens on time. Reporting is built to arrive while the decisions are still open.
Year-round contact
The important conversations rarely happen in April. Planning is spread across the year, when there is still something to do about it.
The neighborhood
Based on Sixth Avenue, working with the businesses around it.
The office sits on Sixth Avenue at 43rd Street, a few minutes from Bryant Park and the corridor of independently owned restaurants, bars, and small companies that keep Midtown running. Many clients are within walking distance; others are across the Tri-State area and work with the firm remotely.
