Our Team

The Practice is committed to the continuous development of its staff. As a knowledge-based enterprise our greatest strength lies in the skills and abilities of those who work for the practice and it is this which will encourage clients to return-this is our ‘product’. It is therefore vital to ensure that staff continue to develop their abilities and build upon their existing skills. All staff regularly attend CPD seminars and courses.

David and Andy follow more strategically based subjects although both have recently been involved in CDM related programmes. Julie follows the horticultural interest of the business.

DWA is proud of its achievements relating to quality which include the continued upkeep of ISO 9001.
