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.

Meet TSS team member Michael Stebbins! đź‘‹

Over 10 years ago in December of 2015, Michael started his career with us as an intern. He began in the tax department working primarily on individual tax returns (1040s), and over the years, his role has continued to grow!

Today, Michael works across several areas, including tax and business valuations. He also spent time on the A&A team, adding to the range of experience he's built throughout his career at TSS.

What has kept him here for more than a decade? The people, the clients, and the variety that comes with the work. đź’™

"This has just been a great place to work overall. The people here are amazing to work with, and you get a very diverse clientele, which is always fun because it's something that's always different."

We're glad to have Michael with us as an essential part of the TSS team! đź«¶
