He said: "There's a unique and valuable level of support, pride and expectation from our supporters and partners in the Scarlets region. I'm looking forward to hearing peoples' views as well as bringing in some new initiatives that I hope will benefit this great rugby region and excellent new stadium.
"This is a superb facility but it has to earn its keep. We will look to expand its profile and standing as a venue for a range of events sports and non-sports alike - there is huge scope and potential here and we will start the process of building an events platform for Parc y Scarlets in the coming months.
"There is equally a wealth of experience, knowledge, expertise and understanding of what it means to be Scarlet which has now come together as a senior management team. With people like Gareth Jenkins, Nigel Davies, Rupert Moon and Jon Daniels leading their areas of expertise, we have a very strong senior management team.
"My job will be to pull all of that together, to help bring out the best in the teams and staff here and to ensure we keep our supporters - 'our customers' - happy and closely connected with us. People will come to know that I like to be accessible, open and frank and I intend to get out and about as much as possible.
"On a personal note, I am delighted to be back in Wales. This country is like a second home to me and my family and so it was an easy decision to come back. I have great memories from my time here and we are looking forward to settling into life in Wales and once again enjoying a life within Welsh rugby."

Scarlets chairman Huw Evans said: "We are delighted to have appointed Paul as our new chief executive. He has a proven track record in leading rugby stadium operations around the world and I have no doubt his experience, energy and great commercial acumen will have a very positive impact on the running of our region.
"His unrivalled understanding of stadium management will ensure that the burgeoning reputation of Parc y Scarlets will continue to evolve and create new revenue streams for us. We built the finest rugby stadium in Europe, now we have one of the world's best rugby stadium specialists to lead us forward and run it."

We've been down a rocky road recently but can now be enthusiastic and positive once more about the future. Paul will bring expertise and stability; this, alongside the development of Nigel Davies's exciting squad, means that we can look forward to next season and beyond with great anticipation."

Paul Sergeant - biography
An integral part of the UK's first National Garden Festival in the mid-1980s, Mr Sergeant then moved on to Wembley where he was quickly promoted to commercial director of the stadium and arena complex. He created one of the most dynamic and successful commercial management teams anywhere in the world and went on to become stadium director.
His reign saw the stadium enjoy the most prolific period in its history. The business became so well recognised around the world that Wembley formed a venue consultancy business to cope with the interest and Paul became involved in projects in Europe, Asia, Australia and North America.
In 1996 he was voted as Ambassador for London. In 1998 he was voted International Venue Manager of the Year and Wembley was voted International Venue of the Year.
On leaving Wembley in 2000, he acted as a freelance consultant in projects in Australia, Germany and South Korea, before joining the Noble Organisation, a privately owned leisure operator in the United Kingdom.
