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! 🫶

“TSS just gets it. They’ve been by my side through partner transitions and acquisitions, and they always support me with thoughtful guidance. It’s rare to find a firm that’s sharp enough to handle the complex stuff but still picks up the phone when you call. They’re more than accountants; they give me real confidence in where I’m headed.” - Scotty Linscott, H.B. Fleming, Inc
