Mantle CPA Group
Built from Big Four experience. Designed for Main Street business

Mantle CPA Group is a CPA firm for owner-operated businesses and the people who own them. We’re built to be the CPA Main Street used to have: someone who knows you personally, understands the business, and sees the full financial picture, not just one piece of it.
Over time, that kind of CPA became harder to find. The accounting profession now faces a deep talent shortage, and Main Street is competing with corporations and large firms for a limited pool of experienced CPAs. In its place, many owners are left with a once-a-year visit — you hand over your documents in the spring, a return gets filed, and no one talks to you again until next year — while coordinating separate bookkeepers, payroll providers, software platforms, and advisors who rarely talk to each other.
We built Mantle differently. We automate the routine work, get your tax foundation right from the start, and spend our time where it counts: proactive tax strategy with you throughout the year, working alongside your other advisors, with the same team preparing your returns.
Built from Big 4 experience, Mantle was shaped around what owner-operated businesses actually need: direct access, responsive service, year-round involvement, and one team that sees the full financial picture.
That is the firm we thought should exist, so we built it.

The Story Behind Mantle
Mantle is named after Henry Mantle, the late maternal grandfather of our firm’s managing partner, Sean.
Abandoned by his parents in middle school during their struggle with addiction, at a time when America had no real foster care system to catch him, he survived one of the toughest upbringings imaginable. At twelve years old, he dropped out of middle school and went to work full-time on the docks of New York — without parents, without relatives, without any support of any kind. The stories from those years are ones few people could believe.
Despite circumstances that could have easily broken him, he went on to build a long career as a truck driver, raise multiple children, and live a long retirement in the Florida sun, as so many New Yorkers do. The hardship he survived built the foundation for everyone who came after him.
In his final years, he often said how proud he was of the life he'd built. But he also hinted, more than once, that if his circumstances had been different, his dream would have been to own his own accounting firm. He loved numbers. He loved hard work. He loved working with people.
Sean built Mantle to live out the firm his grandfather never got to build.
