The People

Trevor McCarthy-White BSc (Hons)


As Whytec's senior consultant and Director, Trevor brings with him a wealth of industry experience and robust personal and management qualities.

From his 25 years in the industry Trevor truly has spanned not only the nuts and bolts “techie” end of the business, but also the creative “solution provider” role, with in-depth management and real-world business projects under his belt.

Trevor is familiar with both working in the Public and Private sectors, large corporations to small one-man businesses, service sector or manufacturing. Past industry experience includes such diverse areas as telecommunications, agriculture, defence, logistics, marketing, insurance, packing and pharmaceuticals. However, he is most conscious of rapidly evolving technologies and markets, and strives to keep abreast of such developments.

On a personal scale, Trevor leverages his technology background when managing his growing music collection.  He is a HiFi enthusiast, a keen all season caravan owner,  and enjoys keeping fit at the gym.

Brian Graham BSc (Hons)

Associate Consultant

Brian Graham is an associate of Whytec Limited. He has been an invaluable partner over the last year and we look forward to working closer in the near future. Many of our existing clients will know Brian from the holiday cover that he provided during the summer of 2010.

Brian’s experience commenced within the electronics industry, working for a private contractor on military defence applications.  Brian’s 15 years IT experience includes Windows Server, PC and network support, relational database development, but his main interest and specialism is in DNS (Domain Name System), Network Infrastructure and Routing.  For the last 8 years Brian has been providing a floating administration and technical support role to many companies nationwide, including multinationals and charity organizations. He has a Bachelor’s Degree in Computing, and further qualifications in Electronics.

Personally Brian loves radio controlled cars, astronomy and can’t get enough of technology in general.  Except on the increasingly rare occasions where he gets the chance to get out on horseback which is his other great passion.

Liz McCarthy-White

Accounts and Administration

As the better part of the McCarthy-White partnership Liz brings truly integrated organisation to the otherwise chaotic Whytec office.

Liz comes from a background as PA to various senior MoD personnel whilst working in Whitehall for many years.  Her flexibility and commitment are clear at night, as the solitary office light confirms, when she is bound to be engaged in the VAT return, paying bills, invoicing, credit control or some other administrative task.  She also gets involved with some of the more technical administrative aspects such as domain, connectivity, hosting, and other renewals administration.

Liz is the mother of three (Stephanie, Caroline, and David), a gym bunny, and enjoys yoga, walking, gardening, and holidaying in the caravan (preferably in the sun!)

Sarah Pearce


Sarah is one of those wonderful people who understand how HMRC and VAT works.

Sarah and Liz have known each other for longer than they are prepared to admit. Together they make sense of the miriad Whytec transactions that happen throughout the year.
