Seabrook Technology Group’s focus is on the use of the latest manufacturing technologies to create value for our clients. Our people are specifically trained to integrate these latest technologies with your business.


In 2010, Seabrook Technology Group’s commitment to a marketing program, aimed at securing business in large scale manufacturing organisations throughout the world, was strengthened by the appointment of new Directors to the Board of the company and the development of a detailed product and services strategy.

William O’Sullivan, a highly experienced IT and MES professional who is a Certified MES Consultant and Project Manager, has also joined the Board.

Our 2012 expansion into the US has saw two new members join the board. John Dzelme, an industry recognized MES expert, and Bill Plunkett, an attorney who has four decades of experience as a practicing lawyer and has litigated cases in every state and federal court in the state of New York.
