Each of our regional hubs across the US is supported by an ambassador, who is an RSA US Fellow that has taken on a community organiser role in their local area.

You can read more about the regional ambassador role here. If you are interested in creating your own local hub then please email Claire Byrne, RSA US Community Manager.

Meet our current regional ambassadors and the regions they help run.
