Our work in the Veliko Tarnovo area of Bulgaria began in 2007 and grew so quickly that we formed a legally recognised non-profit making organisation in 2010.
PRIATELI-VELIKO TARNOVO FOUNDATION was registered in the Court of Veliko Tarnovo on12.07.2010, Bulstat number175917948, and subsequently with the Ministry of Justice in Sofia
‘Priateli’ means ‘friends’ in Bulgarian, and that is what we hope to be to as many needy people as possible.
OUR MISSION STATEMENT
Priateli - Veliko Tarnovo aims to actively promote and protect the rights of vulnerable children and adults in Bulgaria, thus enabling them to access their fundamental human rights to social justice, equality and social and economic independence as enshrined in the European Human Rights Convention.
We embrace diversity and seek to meet immediate basic needs, provide lifeskills and promote lifelong learning, with the intention of equipping individuals with the skills and expertise which will enable them to become socially and economically independent.
