"We would certainly recommend using Dairo Security"

"During a December team meeting the requirement for security cover over the Christmas period was identified. Following a message from Dario Deabreu on Linkedin offering security services, we made contact to discuss our requirements. Dario picked up the call and was quick to act upon our request immediately sending his sons to the site to review our requirements. Cole and Warren came to the site and completed a diligent inspection with our operational staff, and discussed our concerns at length, and formulated a plan to ensure the site would be secure over the Christmas period. The works were completed, and the site was kept secure. We would certainly recommend using Dairo Security based upon the professional courteous service we received.
