What is The Largo Group?

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. 


The Core Principles of The Largo Group Vision: 

  • Flat Fee Approach - allows us to be efficient and encourages open communication from our clients
  • Financial Analysis - not just a financial statement  
  • Personalized Approach - we take the time to build a relationship with our clients as we know every business and client is unique!
  • Education and Guidance - we take the time to communicate our monthly reports to our clients, and are always available for questions
  • A Team of Licensed Experts - we are on-call for all clients at no additional fee. We believe that having a licensed professional involved in monthly accounting ensures your numbers are accurate at all times

In the last five years the Largo Group has continued to provide this innovative approach to businesses and individuals across the U.S.  

The Largo Group is truly The Evolution of Monthly Accounting, and we look forward to working with you on your accounting needs.
