Quinn focuses on estate, tax, and business succession planning for high net worth individuals and clients with emerging wealth. He counsels clients on all aspects of estate planning: from the implementation of core estate planning documents, to complex gifting strategies designed to minimize estate and gift taxes. He also represents fiduciaries and beneficiaries in all aspects of estate and trust administration, including probate, preparation of estate tax returns, tax disputes, and trustee/beneficiary issues. 

Quinn also advises owners of closely-held businesses on a wide range of matters, always mindful of how the business fits within a client's overall succession or exit plans.

Prior to joining Mintz, Quinn specialized in international tax as an associate at a Big 4 accounting firm, was a law clerk in the trusts and estates group of a law firm, and clerked at the Massachusetts Division of Administrative Law Appeals. While earning his law degree at Boston College Law School, Quinn served as editor-in-chief of the Uniform Commercial Code Reporter-Digest.

Quinn is an active member of the Boston Estate Planning Council and Boston Bar Association.
