Meet The Team

The key to the success of TNG is that we set up the Company as a ‘family’ and have continued to grow the business with extended family members. We have always invited the right people to join our Company; people that share our vision and passion for quality and exemplary customer service, but that also have positive attitudes and supportive and caring natures.

Of course, as well as being nice people to work with, we have carefully selected our team based on their experience, qualifications and accreditations, and their approach to working. Many we have developed ourselves through our Training Academy from school and college leavers.

All our Employees are the very best at what they do, and will add maximum value to your project.
