John joined Murray Plumb & Murray as an associate in 1981 and, just six short years later in 1987, assumed the role of Director of the firm. Since 1981, John has worked intensively with virtually every type of law governing Maine land use and regulation. He has assisted clients in obtaining development permits for projects ranging from small daycare centers to multi-million dollar utility plants. John has also devoted much of his practice to helping persons who are opposed to objectionable projects, or who wish to keep development within reasonable limits.  He was selected by his peers for inclusion in the 2014 New England Super Lawyers. He is also AV-rated by Martindale Hubbell.

John is widely recognized for his expertise in all aspects of governmental law. Since the early 1980s, he has represented several municipalities as well as private persons in litigation against municipalities, and has appeared before the EPA, FERC, FAA, and Army Corps of Engineers at the federal level, the BEP, DEP and LURC at the state level and before the zoning and planning boards, Boards of Selectmen, and Town Councils of most municipalities in Maine. Finally, John has devoted much of his attention in recent years to the investigation and litigation of complex boundary disputes with regard to all aspects of his practice. John frequently argues cases before the Maine Law Court and Superior Courts throughout the State.

John currently resides in West Cumberland, where he devotes his spare time to restoring an 18th-century cape and surrounding 16 acres of fields that he rescued from irresponsible development as a multi-lot subdivision.

“Master of property dispute resolution. Meeting and working with John Bannon was the bright spot of an unpleasant property dispute with our neighbor. He’s super-smart but able to explain complicated matters in lay terms. His research skills and doggedness were fantastic and made all the difference in our case. A voice of intelligence, reason and calm, an iron fist in a velvet glove, an excellent lawyer.” – anonymous feedback from
