MedAid is a UK Charity

Supporting communities suffering the effects of war

Our Story

MedAid was founded in early 2022 by Charlie, Gavin, and Nick, and was soon joined by Kat, Eddie, Ariane, and Catherine. The founders and Ariane shared a common background in finance and journalism in Eastern Europe during the 1990s, as well as a renewed commitment to supporting Ukraine—firstly in achieving peace and stability, and secondly in advancing the development of civil society in the post-Soviet era.

In the immediate term, this meant helping Ukraine in its hour of need—and that remains our mission today. We quickly identified medical services and supplies as an area where we could have the greatest impact; greatly assisted by Kat, Eddie, and Catherine, who brought many years of medical and mental health expertise and connections into the leadership.

The timeline below shows how we’ve built strong partnerships on the ground and received vital support from several foundations and many generous individuals.

Today, MedAid International is an established UK charity delivering medical supplies, mobile doctor services, and mental health support in Ukraine. We work closely with local partners—including healthcare providers and mental health agencies—to ensure that donor funds are allocated effectively and create meaningful impact.
