Our purpose is simple: to create value for our team, clients, and community by giving tax teams clarity, confidence, and control over their tax obligations.

Founded on Years of Expertise
Michael Brennan, founder of The Brennan Group, has been helping businesses navigate the complex world of state and local tax since 1985. As one of eight children in his family, being a good steward of financial resources and helping others are in Michael’s DNA.
Michael believes that less government and accurate taxes fuel the growth of companies, people, and communities. This drives his dedication to providing expert tax solutions that protect businesses and ensure they pay no more than their fair share.
