Connecting with medical personnel in Angola

Hi folks:

I am returning back to Angola (Lubango) to run a mission hospital there after being out of the country for some 8 years.  I previously worked in Angola all through the '90s with a NGO aviation organization.  I want to connect with expat individuals in the medical industry in order to make connections and to network. It would be great to meet and connect with people of this vocation out there and with those that are interested.
