The Association of Energy Correspondents of Nigeria needed a day that did more than fill a hall. The brief was a room in which correspondents could hear a serious argument about the energy landscape, ask unscripted questions, and leave with language they would actually file.

Cettle designed the guest architecture, the run of show, and the briefing so Dr. Charles Ebereonwu’s session could hold under live questions. The result was not a highlight reel. It was a convening the association still cites when it talks about what a serious room looks like.
