About Promark Corporation

Promark Corporation was founded in 1983 by Freddie Leonor.  Since then, we have grown to represent over 30 manufacturers of water and wastewater treatment products and systems, and a full line of pumps and accessories for every application.  While Promark Corporation has been in business for over 30 years, Freddie himself has over 40 years of experience in the industry.

Our business model is based on creating and maintaining strong relationships with our customers, manufacturers, engineering consultants, and contractors.  We believe that through effective communication, a high level of trust, and our vast experience, we are part of a team that results in successful projects in this challenging industry. 

In addition to covering the entire State of Hawaii, Promark Corporation also covers projects in Guam and American Samoa, as well as the former US Trust Territories that are now:  the Commonwealth of the Northern Marianas, the Federated States of Micronesia, comprised of Kosrae, Pohnpei, Chuuk, and Yap, the Republic of the Marshall Islands, and the Republic of Palau.

Promark Corporation also has a subsidiary company, Promark Process International Corporation (PPIC), which operates in the Philippines with its own management, engineers, sales staff, and service professionals. PPIC represents many of the same manufacturers as Promark Corporation, but there are differences, so please contact us for more information about projects in the Philippines.
