Meet The Board

John Brennan, Chief Executive Officer.

John is the founder and Chief Executive of the company. Recognized as an innovative adopter of emerging technologies, John began his career in the late 1970's as developer of applications for the European Space Agency.

By 1990, he was convinced that the future lay in Open Systems and established Brentech Data Systems to take advantage of emerging technologies. Brentech Data Systems was soon providing IT expertise to large corporate clients and supporting and managing the Nokia Data customer base in Ireland.

Within two years, John had developed AWARDS, a new "best-of-breed" application which targeted distribution organizations focused on increasing efficiency through technology. With AWARDS John lead Brentech Data Systems to become the leading solution supplier to the pharmaceutical wholesale sector in the British Isles.

Today, John continues to monitor new and emerging technologies and remains committed to providing industry-leading solutions to a global market.
