Dan Doiron, CPA, joined ARB in 1986 as a college intern and became a Principal with the firm in 1996. He has spent his career delivering tax compliance and planning services to high-net-worth individuals and families, corporations, partnerships, LLCs, estates, trusts and private foundations. As part of ARB’s Tax Group and Private Client Team leadership, Dan uses his expertise and practical judgment to guide clients through tax compliance challenges and tax planning opportunities. He limits the use of his CVA designation to providing only tax-purpose related valuations.
Adept at translating complexity into clear recommendations, Dan has presented seminars and written articles to assist peers and clients with their understanding of tax issues. He advocates and strives for a thorough understanding of technical matters, providing advice and counsel to some of the largest private foundations in Maine, advising business owners on entity-selection, and navigating complex multi-state, fiduciary, and gift tax compliance issues.
His long tenure and leadership at ARB reflect a commitment not just to excellence, but to empowering clients and guiding the firm’s tax advisory vision. Dan successfully led ARB’s transition to a paperless environment in 2005 and has been significantly involved with advancing the firm’s use of technology over the years.
Earlier in his ARB career, Dan also managed audit and accounting engagements, building a strong foundation in financial reporting and understanding of business operations. That foundation continues to shape his leadership in delivering comprehensive, insight-driven tax solutions.
Dan lives in Brunswick, Maine, where he values time with family, friends, and the open road. A Corvette owner who loves autumn road trips, he plans to rediscover his golf swing soon and demonstrates his commitment to community service as Treasurer of the all-volunteer staffed Brunswick Area Student Aid Fund.
