Since 1974, starting in New York and New Jersey, I concluded sales of capital equipment and services, to the maritime industry, public utilities and government agencies. I was employed by manufacturers, and companies representing U.S., European and Japanese manufacturers.  Related responsibilities included: Regulatory approvals; proposal; presentation; demonstration; on-site supervision of installation; sub-contracting and personnel training.

Keller Maritime Associates was established after I moved to California in 2005. I introduced and sold a pipe repair and construction product to vessel operators, cities and utility districts. As a Sales Associate of C & C Panasia, I sold Ballast Water Treatment Systems to ship owners and shipyards.
