Terry Doherty

Terry Doherty founded the company in September 1991, starting in a serviced office with the aim of building a managed services business.


Terry is the Founder and Chief Executive Officer of Doherty Associates. Now in its 27th year, the organisation has multi-country presence, a global client base and a team of more than 80 people working round the clock.

The business initially specialised in providing IT to cruise ships in the 1990’s where remote technology support for was a novel concept. He then applied these learnings to other industries operating in inaccessible locations, such as mining and oil and gas companies. Under Terry’s leadership, the company’s cloud customer portfolio has quadrupled in the last three years and now spans across most industries and includes purely cloud and hybrid solutions.

Terry is known in the industry for his entrepreneurial nature, as acknowledged in the UK Technology Parliamentary Review published by the UK Government last year. True to his style, he was one of the early adopters to set up an Microsoft Cloud practice, and the company is now in its 15th year as a Microsoft Certified Gold Partner. Terry is a keen photographer and golfer. He lives in Chiswick, London, and has two children.
