David Bullen

Operations Director

Email David My profile

David’s career story is very much one of man and boy at Sharmans. Joining the business formed by his grandfather, Harold Sharman, as a school leaver in the eighties, David has served the company for 30 years. During this time he has learned to run, maintain, design and build machinery that is today deployed in the manufacture of Plygene Gutterline and the other products offered by Sharmans.

Supported by his production and engineering teams, David has continuously improved the factory, its systems and processes to deliver growth whilst maintaining the quality and service on which the company has built its reputation. He also plays a key role in product development and purchasing.
