Overgaard-Nielsen is GDP who started NHS Dentist, an NHS dental practice in Fulham, London in 1999.[6] The practice was started with Sharon Bierer, his British-born wife.[7][8]
In 2013, following a 2012 holiday in the country, Overgaard-Nielsen and Bierer founded a charity, Burmadent, to provide dental services in the Inle Lake area of Myanmar (Burma).[9][10]
Overgaard-Nielsen considers himself to be a socialist, in 2020 booklet Reclaiming Democracy: The Left Case for Sovereignty that he co-authored with fellow Brexit Party MEP Claire Fox, he said that when he campaigned against the Maastricht Treaty in his native Denmark in 1992, "the 'No' side was dominated by socialists and supported by intellectual and artistic elites", but when he moved to the UK in 1996, he found the Euroscepticism there anchored on the right and far-right, while the intelligentsia was mostly pro-EU. He explained his left-wing eurosceptic views by saying that "The EU is rooted in four holy ‘pillars’: unregulated movement of capital, goods, labour and services. The most ardent cheerleaders for these freedoms are large multinational corporations, lobbyists and the middle-class establishment."[14]
