Sullivan Mahoney LLP’s clients include Niagara’s most prominent and longstanding corporate entities and an impressive number of its small, medium-sized and growing businesses.

Get access to specialists and well-rounded advice.

Rather than generalists in the area of business law, many of the lawyers in our group have a specialization in one or more of the areas of expertise below. With a focus on areas like administration, construction liens, mergers and acquisitions, and contracts, our lawyers can effectively serve clients with specific needs. When clients’ needs cross over with tax, construction, or employment areas of the law, they have access to other resources and practice groups within the firm, which enables them to provide comprehensive and all-encompassing advice.
