Corporate History

1958 - Present

Milestones That Shaped Us

Founded in 1958 by Peter M. Gandolfo Sr., OHM International evolved from a regional wholesaler into a global provider of electrical, industrial, and telecom solutions.

This Business Plan

Upon graduating from Fordham University in 1947, Peter M. Gandolfo Sr. joined Graybar Electric as a sales representative. In 1958 he resigned his position with Graybar Electric, and founded OHM Electrical Supply Co. in Elmsford NY. Rather than introduce another “supply-based”, distribution outlet to the market, PMG Sr implemented a unique “demand-based” distribution model to the market allowing the customer’s product needs to drive the transaction rather than OHM’s available inventory. This business plan flourished, and in 1967 OHM constructed a 40,000 square foot warehouse in Hawthorne NY to accommodate the rapid growth.

The Presidential "E" Award

In 1975, a subsidiary, OHM International of Texas Inc. was formed to handle the increasing export opportunities in the oil and petrochemical related industries.

This office was opened in Houston and Mr. Peter M. Gandolfo Jr. was appointed to manage the Houston operation. Over the ensuing decade, OHM experienced tremendous growth, and in 1978 The Presidential “E” Award for “Excellence in Export” was awarded to OHM International, Inc. by Congressman Richard Ottinger and officials of the U.S. Department of Commerce. Cited was the company’s “outstanding contribution” to the Export Expansion Program of the United States of America.

OHM acquired by Anixter

By 1980, OHM International had a customer base spanning 95 countries worldwide, and was gaining national attention. In January 1981, OHM Electrical Supply Co. and its subsidiary, OHM lnternational, Inc., were acquired by Anixter Bros., Inc. (a NYSE traded corporation: ANX) and reorganized as “Anixter-OHM International”, a publicly owned subsidiary of Anixter Bros., Inc. Peter M. Gandolfo, Sr. remained with the new entity as President and simultaneously served as a Director of Anixter Bros. Peter Gandolfo, Jr ascended to Vice- President of Anixter-OHM International.

OHM re-privatizes in buyback arrangement with Anixter

In December 1983, Peter M. Gandolfo Jr. re-privatized OHM International Corporation in a buyback arrangement with Anixter. OHM’s corporate headquarters are moved from New York down to Houston Texas.

P. Michael Gandolfo III

In March 1996, P. Michael Gandolfo III joined OHM International representing the 3rd generation of the Gandolfo family to be actively involved in management. Upon his arrival, and with the wave of enthusiasm towards e-commerce, OHM implemented EDI trading agreements with its largest customers, as well as with 100’s of US Government entities. This electronic venue increased both sales & productivity.

OHM opens 7 overseas JV offices

In 1999, OHM International modified its marketing approach for select countries and established a Venezuelan office, (CS-OHM de Venezuela). This Joint Venture served as the template to their strategy, and provided OHM access to the Venezuelan market with offices and warehousing in Caracas, Barcelona, Valencia and Maracaibo.

This Overseas JV Location is the 1st of 7 to be implemented. Other JV offices formed and opened were OHM-Tekmin in Peru, OHM-Danielcom in Ecuador, OHM-Comsertec in Bolivia, OHM-DRM in the ABC islands (Aruba, Bonaire, Curacao), OHM-IEOS in Libya & OHM-ICON in Dubai.

In Japan, the office is originally classified as a JRO, but later fully incorporates as a K.K. and resides in Tokyo, while in Mexico the office is a fully incorporated subsidiary, OHM de Mexico S. de R.L. de CV and is headquartered in Tampico.
