The value of a well-regarded relationship

A long history in the Hamptons and on Long Island
Our roots go back to three prominent CPA firms on Eastern Long Island: Markowitz, Preische and Stevens, P.C., Fenelon, Crowley & Tutino, CPA, P.C., and Mac Albert Bank & Co., P.C. In 1998, all three merged to become Markowitz, Fenelon & Bank, LLP, or MFB.

We serve personal and business clients in both the West End and East End of Long Island, offering local knowledge and relationships with leaders in our key industries.


The right approach with your future in mind
Given our accounting background, it’s in our nature to err on the side of caution. However, reward must always be appropriately balanced with risk. We are open to entrepreneurial vision and questions about new approaches, and we weigh that innovative thinking against careful stewardship of your financial position at each stage of life and business.


Personal attention makes a difference
The foundation of our business is the relationships we earn with our clients. Applying a holistic approach, we address our clients’ needs for today and help them plan for tomorrow. It’s what we enjoy the most — making and creating connections.

We believe our clients receive a high level of personal service. One fact that we’re proud of is that even when our clients retire or move away, they tend to stay our clients. In fact, we love getting personal updates on their lives across the US.

Service you deserve. Advice you trust.
