Board of Directors

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.

Dr. Paddy Caffrey, former Vice-President of Pfizer Ireland is Chairman of the Board of Directors and he is joined by Dick Lehane, former worldwide Vice President of EMC Corporation. 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, including 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.  

In early 2019, William O’Sullivan became Global Chief Operating Officer, with a focus on business growth and expansion.
