Meet some of the team responsible for providing technical support, project consultancy and account management to our London clients.
ISN head office staff
David Greenwood – Managing Director
David started his IT career at Barclays Bank in New Zealand, where he became operations manager for the company's mainframe systems. On moving to the UK he expanded his technical and management skills at Enterprise Oil as well as Hardy Oil and British Borneo. David's wide experience, cool judgement and instincts for technical excellence are key to shaping ISN's service to our clients.
David Ellison – Director
Although David has a language degree, he discovered early on that IT concepts and programming languages came just as easily. His understanding of how to get the most from IT systems without losing sight of the commercial aspect has been key for consultancy roles at Enterprise Oil, Flemings, NatWest, and Fortis. David enjoys helping ISN clients develop innovative IT strategies that maximise their investment as well as honing ISN to provide world class IT services.
Derek Munro – Director
Following an honours degree in Electronic and Information Engineering at RGU in Aberdeen, Derek began his career as a Communications Engineer for Enterprise Oil. A Chartered Electrical Engineer and proficient Project Manager, Derek has a track record in delivering large IT and telecommunication projects around the world.
He splits his time at ISN between managing our operations department and account management for key clients. ISN and our customers, benefit from Derek's focused approach in meeting their goals.
Alex Billowes – Engineering Manager
After a degree in Computer Science, Alex developed his IT experience in business consulting, county councils, newspapers and insurance before joining ISN in 2002. Although his technical expertise is second to none, what he enjoys most is working with customers to define and realise their goals.
His ability to steer his engineers through complex projects make him an invaluable member of ISN's management team. Clients say that they know their problems will be solved if Alex is on the case.
