Mengel Metzger Barr & Co. LLP is proud to have merged with Albany based Marvin and Company, P.C to form MMB + CO effective January 1, 2023. Prior to this merger, MMB + CO, a Rochester, Canandaigua, and Elmira, New York firm of certified public accountants and consultants, has been providing accounting, audit and tax services since 1975. With the merger, the newly combined Firm now has locations in Canandaigua, Elmira, Latham, Queensbury, and Rochester, NY, covering a vast area of New York State. With over 200 employees, we look forward to continuing our focus on providing a positive and supportive culture for our employees in all offices.

At MMB, our focus is on the here and now, helping ensure a strong and vibrant future for each of our clients. It’s this forward-thinking, client-centered approach that has guided the firm since 1975 and made MMB one of the most respected and successful accounting firms in the field. 

We’re proud of our rich history of service to our clients, our profession and our community. And just as we have over the past four decades, we’ll continue to strategically grow in ways that enable us to meet the ever-changing needs of our clients. Our deep talent pool is a thoughtful mix of old-guard experience and young-lion innovation, combining years of in-the-field wisdom with the innovative thinking our most-recent hires bring with them from today’s leading universities. We’re proud, too, of our staff development, helping each employee maximize talents, explore interests and hone skills.
