Experienced Accountants with a Simplified Approach

Our proactive accounting system is designed to provide the peace-of-mind every business owner and individual deserves.

What is The Largo Group?  In musical terms Largo means methodical.  The vision for our company is to offer a methodical approach to accounting and tax services so that the business owner has the key information they need in real time.  

The Largo Group was founded by Anne Gannon, CPA in 2016.  Anne has 15+ years experience and began her career as a CPA with a big-five accounting firm in Boston, MA where she quickly realized the only winner in the 'busy season' approach was the accounting firm. 

As the daughter of a life-long entrepreneur, Anne set out to form The Largo Group based on the fundamental ideal that monthly accounting and tax services could be done in a more efficient way.
