Marketing - yes we can!
Sure, marketing is a well known term. The onOffice marketing department is responsible for the overall communication. It is the contact platform name for press and media. We are in charge of the onOffice print and online media ranging from flyers to newsletters, from the digital information to all sorts of campaigns and events. We further keep one eye on branch-related occurrences and analyze the real estate market. We are the ones developping company goals and implement them strategically.
