Since 2004, Mary has steadily worked to establish her relationships with various organisations, their issues, missions, programmes and staff. Her patronages range across areas of culture, the fashion industry, humanitarian aid, support for research and science, social and health patronages and sport (golf and swimming). The organisations for which she is patron have reported positive outcomes through their relationship with her and there are various reports in the Danish media and on some of the websites of the organisations themselves about her being quite involved in her working relationship with them. She is currently involved in supporting anti-obesity programs through the World Health Organization, Regional Office for Europe.
