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.

Andy Thompson

Operations Manager

Andy is a highly respected security professional with a unique breadth of experience across a wide range of related management roles. Andy is a highly respected security professional with a unique breadth of experience across a wide range of related management roles.

After serving as a junior non-commissioned officer in the British Army, Andy joined the police serving initially in Kent before transferring to Merseyside.

After leaving the police to pursue a career in the private sector, Andy was appointed as a security manager for one of the world’s biggest logistics companies. It was at this point in his career that Andy appreciated and understood the value of providing businesses with high quality manned guarding and physical security services.

After leaving the logistics sector, Andy worked on a consultancy basis for several north west based security companies. It soon became apparent that there were glaring discrepancies in the quality of services promised and ultimately delivered to the client. Customers were being short changed and in GSTS, Andy found a security company who shared his ideals of integrity, professionalism and a commitment to excellence.

“I am proud and privileged to join the GSTS family at this exciting time in the companies’ evolution. I know the management team well and they share the same desire as me to provide customers with exceptional service in an industry where for too long, they have been taken for granted.”

Robbie Whelan

Training Manager

As our dedicated training manager, Robbie has a varied and extensive training background from his time in the British Army and latterly, in the private security sector.

During his 16 years in the army, Robbie reached the rank of sergeant and was one of the relatively few, elite instructors given the responsibility of training new recruits at the Army Training Regiment in Winchester. This is a role that Robbie enjoyed immensely and ignited his passion for training. He gained immense satisfaction from turning ‘civvies’ into fully fledged soldiers. Robbie is a qualified army firearms, physical fitness and adventure training instructor.

Robbie completed tours of duty in Northern Ireland, Macedonia as well as three tours of Iraq and five of Afghanistan. He understands exactly what it means to work under pressure and lead a team.

On leaving the army Robbie worked abroad carrying out operational security work in north east Africa and specialist security training in Saudi Arabia.

On returning to the UK Robbie worked as concierge and security at numerous high-end jewellers across the North West and North Wales. Robbie was also a Team Leader for UK Military Schools consisting of delivering a standard intervention course of team building, physical education and field skills to raise attainment through a military ethos to key stage two children across the North West.

“I am passionate about training and helping people get the most out of themselves. I like to make training interesting and enjoyable. Not everyone learns the same way and I understand that different people require different styles of delivery. I am excited to be part of a company that shares my enthusiasm for training and development”

Alex Campbell

Client Relationship Manager (North West)

Alex has spent over 30 years in the Security Industry in various roles and organisations, from the bars and clubs of Liverpool to being part of the Security Team for Cavern City Tours, a world renowned business, where he had responsibility for the security of customers and celebrity clients including Sir Paul McCartney and Hollywood actor Billy Bob Thornton, to sharing the organisation for the security staffing at the annual Mathew Street Festival in Liverpool.

Prior to this, Alex travelled extensively throughout Europe providing security at a number of high profile festivals and events including Roskilde and the Roger Waters concert to celebrate the fall of the Berlin Wall.

In his most recent position, he was a member of the team providing security services to Liverpool John Lennon Airport licensed taxi area as per Liverpool City Council guidelines and LJLA standards. Over the years, Alex has gained a wealth of knowledge in the Security Industry, both customer and client focussed and he prides himself on the working relationships he’s forged along the way.

“I am delighted to be joining such a go ahead company as GSTS, I very much enjoy the front end role of client management as I feel that I am the original people person. The values that GSTS have of putting their front line staff first, really fits my own views, as it is what the security industry has neglected for many years”.

José Luis Sevilla Camins

Client Relationship Manager – Loss Prevention

José Luis Sevilla Camins

José spent twelve years as an officer in the Guardia Civil, the national Spanish police force where he underwent intensive training, including drugs surveillance, public order and counter terrorism. His last posting was in Madrid’s elite crowd control department.  Since moving to the UK with his family, José has qualified as an SIA door supervisor, and latterly as a Close Protection Officer.

He has considerable experience in working in the high-end retail sector and has been commended several times by clients and the police for his interventions to break up organised shop lifting gangs targeting luxury goods. José is committed to continuing professional development and has recently commenced GSTS’s Behavioural Analysis advanced training programme. His Close Protection and language skills have meant that he has also been used as an advisor to several high profile Spanish speaking sports and film personalities. José relishes his time living and working in Liverpool and states that his favourite meal is now a full English breakfast. He has quickly become an important part of the GSTS Team:

“With an emphasis on our senior team having police and military backgrounds, I feel that my time as a police officer in Spain fits in very well. We have always had a problem with organised criminal gangs and my experience has taught me to know how these thieves think and operate.”
