Dave Potts


Dave is one of the most experienced and respected security professionals in the UK with a proven track record of developing contracts and working with some of the biggest blue chip companies across the world.

He had an extensive career in the police, which included CID, firearms and Crime Prevention. He also worked in local government as a Community Safety Manager and was involved in projects which led to the instigation of Police Community Support Officers. He is regularly asked to speak on regional and national radio as an expert in public order.

Dave is passionate about training and the standards of client care in the industry:

“I believe that our methodology of basing all we do around high quality training is going to become key to our continuing success in attracting world class clients to our company – For too many years the industry has failed to inspire staff in this area and effectively taken them for granted, we want to change that for good.”

There are no ivory towers at GSTS and Dave enjoys spending as much time as possible with our frontline operatives.
