The Concordia 2018 summit was great. Vibrant, weighty, and filled with fascinating people. We are delighted to have been there and spoken to two of the most interesting for this week’s Rostrum. First up is Dennis Walto, CEO of the Children’s Health Fund. His organization does vital work, and you need to know more about it. Then Serge Imbeh, an insurgent African politician that some are calling the Macron of Madagascar.
