In 1988 Barjesteh established his publishing firm, specialising in history, culture and genealogy.
[3] Also in 2000, he was (together with Jan Bomans, lieutenant colonel Eppo Brongers and Ad Vermeulen) one of the initiators of the monument for Johan Willem Friso, Prince of Orange (1687-1711) at the Moerdijk.
The project focussed on the Y-chromosomal DNA and at that time was unique as it combined genetic profiles with pedigree lines going back centuries.
[9][10][11] The publication of the book Honderd Schiedamse Families in 2010[12] led to an accompanying exhibition: Rijkdom van de stad.
[14][15][16] After purchasing an old monastery in Eijsden, Limburg,[17] Barjesteh in 2013 founded the International Museum for Family History in the Ursulinenconvent.
