About
John R. Dunnell is Senior Attorney and Director of Tax and Trust Administration at Generations Law Group. He has practiced for more than thirty years, focusing on estate planning, trust and estate administration, and fiduciary income taxation. His work addresses the planning, administration, and tax issues that arise when individuals create estate plans or when fiduciaries manage trusts and estates after a death.
John attended Boston College Law School, completing his legal education in 1987. He received a Bachelor’s degree from Bates College in 1984. His legal career has included service as a principal attorney with Russell Plummer & Rutherford, P.C. That background supports current work involving estate documents, fiduciary responsibilities, trust administration, estate administration, and income-tax questions connected with trusts and estates.
John’s current responsibilities place tax and trust administration alongside his estate planning practice. He works on matters that require coordination between legal documents, fiduciary duties, asset administration, and tax reporting. His professional involvement includes the American Bar Association’s Closely Held Business Committee and Business Succession Planning Subcommittee, reflecting experience with estate and succession concerns that can affect families, business owners, trustees, and other fiduciaries.
John R. Dunnell has been recognized by Boston Magazine as a Five Star Wealth Manager and serves on the board of Towards Sustainability Foundation.
