Here’s why you’ll enjoy working with him.

Whether it’s international, federal, or state tax planning, business succession planning, or estate planning, Nelson is ready with thoughtful, practical, and effective guidance. He is eager to provide clear explanations of tax policies and help his clients swiftly and confidently navigate the tax consequences of even the most complex transactions, including mergers and acquisitions, tax-free exchanges, reorganizations, and municipal and private activity bond financing.

Nelson advises educational organizations, health care agencies, hospitals, and nonprofits on a range of tax matters, including Maine sales and use tax issues, real property tax, and public charity and private foundation status. He frequently shares his expertise at seminars for the Maine Bar Association and with law students at the University of Maine Law School as adjunct professor of estate and gift tax. In 2007, Nelson received the firm’s Barnett I. Shur Civic Award in recognition of his steadfast service to the community.

But that’s not all. Nelson is also very experienced in:

  • Advising charitable organizations on private inurement and private benefit matters
  • Counseling individuals on their various estate planning options, like revocable and irrevocable trusts, gift planning, family limited partnerships, and limited liability companies

In his former life, Nelson was:

  • Working in the Boston office of Grant Thornton, an international accounting firm.

When Nelson isn’t working, he is…

Serving on various committees at the Woodfords Church and Mercy Health Care System of Maine. Otherwise you’ll find him putting his green thumb to use in the garden, or out on the green perfecting his putt. He also enjoys biking, hiking, and playing softball.
