About Tyler, Simms & St. Sauveur

Why We Are Different

Founded in 1986, Tyler, Simms & St. Sauveur, CPAs, P.C. has grown to become the largest CPA firm headquartered in the Upper Connecticut River Valley of New Hampshire and Vermont. 

With over 50 employees dedicated to the broad range of clients and mix of services seldom seen in a local firm, we have experience and expertise to assist our clients in meeting their goals, whether individuals or business entities, regardless of their size or industry.

At TSS we recognize that diversity is just as important in our industry as it is in yours. It is no longer sufficient for a CPA to be simply a preparer of financial statements and tax returns. CPAs today need to be business consultants, advisors, planners and strategists. We need to be knowledgeable not only in accounting and tax law, but also in business analysis and valuation, estate planning, employee benefit administration and much more.
