ISS Facility Services A.E.
At UNISON we help our customers work in a safe, clean and healthy working environment. In addition, we relieve them of the burden of managing and maintaining building facilities – so they can remain focused on their core business – while committing to a superior level of service delivery.
We began our journey in 1977, as a subsidiary company of the multinational ISS service provider group. Today, we lead and develop the Facility Management industry in the country, having received the experience, know-how and innovative practices from the global ISS group of companies, of which we remain an exclusive partner.
