Accounting and Consulting Firm BerryDunn Reaches Milestone 50-Year Anniversary


Built on a strong foundation, BerryDunn has continued to help clients thrive by fueling innovation for over half a century. 

Beginning by opening its first office in Portland, Maine, in 1974, BerryDunn now has employees living and working in 51 US states and territories, providing accounting, tax, and consulting services to thousands of clients in over 30 industries. The firm is celebrating its 50-year milestone by continuing to create connections among its people, giving back to the communities where they live and work, and showing gratitude to its clients. 

To commemorate this special year, the firm announces “50 Acts of Caring,” inspiring employees to provide community service where they live and work—from the United Way challenge to all other meaningful community service. BerryDunn's connection to communities has always been the foundation of who they are as a firm, and this connection has greatly contributed to its longevity and success.   

“Promoting strong connections between our employees, our communities, and our clients makes us who we are today,” explains Sarah Belliveau, President and CEO. “Our clients are the reason why we do what we do every day, building on a foundation of trust. These strong, lasting relationships brought us to where we are today as an award-winning firm after 50 years.” 

BerryDunn continues to thrive by honoring its past and celebrating its future. The firm has expanded to meet the demands of high-growth industries such as healthcare, financial services, renewable energy, and state and local government. By attracting employees with expertise in these areas, BerryDunn has strengthened its national presence.   

“We are focused on listening to our clients’ needs and translating that into effective solutions for them in an ever-changing landscape,” explains Belliveau. “Because of our deep industry expertise, we can anticipate what is on the horizon and proactively help our clients take advantage of new opportunities, addressing emerging risks quickly and effectively.”
