Who you work with

Personal attention, professional standards

MDS Management and Accounting Services is an independent practice built on a simple idea: small businesses deserve the same financial clarity and care that larger companies pay teams to provide.

When you work with MDS, you work directly with Maurice “Moe” Sullivan — the person doing the work — not a rotating desk at a large firm. The result is accounting you can trust, explained in plain language, delivered with diligence and genuine care for the people behind the business.
