Reina managing director Ricky Reina said: “The future feels bright. Being aligned to the Jenner brand, which is so strong and respected as one of Kent’s leading contractors, I believe will reap huge benefits for us all at Reina. I am incredibly excited for the potential opportunity this provides for both our businesses”.
