Founded in 1986, TSS Advisors (formerly Tyler, Simms & St. Sauveur) has grown to become the largest professional advisory firm headquartered in the Upper Connecticut River Valley of New Hampshire and Vermont. With over 50 dedicated employees offering a diverse range of services rarely found in local firms, we at TSS Advisors possess the experience and expertise to support clients of all sizes and industries—whether individuals or business entities—in achieving their goals effectively. Our mission is to make a difference in our clients’ lives, and forge legacies for generations to come.

At TSS, we understand that diversity is crucial, not just in industries we serve but within our own firm. Today’s professional advisory services demand more than the traditional roles of preparing financial statements and tax returns; our professionals are consultants, advisors, planners, and strategists. We are well-versed not only in accounting and tax law but in business analysis, consulting, estate planning, business valuation, and a wide array of additional disciplines essential for comprehensive client support, ensuring comprehensive and tailored guidance. As an independent member of CPAmerica, we have access to resources from the Crowe Global network that consists of more than 200 independent accounting and advisory services firms. 

Over the last few years, we have recognized and embraced the evolving landscape of the accounting profession and industry. In our commitment to excellence, we are excited to announce our partnership with Ascend! This collaboration will elevate our strategic growth model by granting us access to limitless resources, leading technology, and expanded partnership opportunities, enabling us to better position our employees, serve our clients and advance our firm’s capabilities.
