I wasn't sure at first but my boss kept talking about PHD Nigeria for our hospital's advertising needs so I eventually asked what they actually did. Turns out they handle the whole media planning and buying thing, not what I initially thought based on the name lol. The team explained everything clearly and didn't make it complicated like some of these places do, and honestly their approach to getting our hospital's message out there has been sharp. Already seeing better results than the last people we used.
