John Martin, President, founded Martin Associates in 1986. Over the past 40 years, Dr. Martin has conducted more than 1,000 port economic, planning and marketing studies for seaports, terminal operators and ocean carriers in the United States, Asia, Europe, the Caribbean and South America.

He also provides ongoing economic and planning consulting services to terminal operators, ocean carriers, and government agencies, as well as to the major airports in the United States.
Dr. Martin has developed several strategic plans for a large number of key U.S. and international ports, which include the development of distribution center strategies and logistics centers, as well as the economic assessment of alternative uses of waterfront land, particularly the impact of non-maritime development that encroaches upon the maritime cargo uses of the land. He has conducted numerous studies regarding the growing size of vessels, potential impact of the expanded Panama Canal, and the increased use of the Suez Canal on port infrastructure needs in the U.S., as well as on the development of transshipment hubs in the Caribbean and Central America. He has recently evaluated terminal development in Trinidad, Jamaica, and Puerto Rico, as well as terminal development in Ireland.
Dr. Martin also assists numerous port authorities, national and international terminal operators, ocean carriers and private investment groups in developing long term public private partnerships to develop marine terminal infrastructure, and assess the enterprise value of marine terminal infrastructure. He is a featured speaker at numerous American Association of Port Authority Conferences and is a regular keynote speaker at international conferences in London, Rio de Janeiro, Istanbul and France. These international conferences focus on the presentation of Dr. Martin’s work regarding the development of public private partnerships for marine terminal development.
Dr. Martin shares his knowledge in the Lancaster Community by serving on his Alma Mater’s Entrepreneurial Board.
