Connecticut Audit, Tax and Consulting Offices

Delivering the Power of Being Understood to Connecticut 

Since 1989, RSM has had a strong presence in Connecticut. In 2001, RSM acquired Messina, Ceci and Archer Company, expanding its operations into Fairfield County. In 2014, the addition of a wealth management practice further expanded our capabilities. Today, the firm maintains offices in Stamford, New Haven and Farmington. Our Connecticut practice combines full-service capabilities with deep resources, industry insight, practical advice and senior-level involvement to help middle market companies in our area succeed.

More than 200 employees across the Connecticut offices provide services to more than 1,000 businesses and over 5,000 individuals in the area. We participate in a variety of professional organizations at the local, state, regional and national level to ensure we stay informed and connected to the issues affecting our clients.

As a national firm and through our affiliation with RSM International, we are able to provide customized service plans for clients that operate in multiple states and internationally. 

Commitment to the Community

Our commitment to Connecticut extends beyond serving the needs of our clients. Our employees devote their time, money, talent and energy to many local charitable organizations, fundraisers and events. For example, in 2015 RSM raised nearly $56,000 for Make-a-Wish Connecticut through the firm’s Birdies Fore Love program as a part of the 2016 RSM Classic. .
