Trees has lived in the north of Israel together with her husband Ali Zbeidat since 1993. She has been a contact of the Foundation Friends of Nazareth for students in the north of Israel since 2008.
On women’s day 2007 she noticed a Contact letter laying around. This was the start of an intense contact between her and the Foundation.
Since November 2020 the SANA board currently consists of five members. Trees included. "We do whatever it takes to continue and develop the SANA Foundation. Recently Raghida MiaraZbidaten and Khulud Furani. The latter is a former colleague of mine and a person very much interested in the work of Sana. Together with Ruud Kronenberg, Sanaa Azizi and myself the board is now complete. Unfortunately, due to Corona restrictions we haven’t been able to meet in person and so we inform each
other by WhatsApp and Zoom. We hope that this period so difficult for everybody will soon come to an end, so that we go about our business as usual.
We are now the ones responsible for "the mental guidance and financial support of nine students in our own scholarship programme. In the past few months, we have accepted four new students. We are very grateful to the Stichting Vrienden van Nazareth and the Stichting Lavra Netofa. Their financial contributions enabled us to select these students and guarantee them grants for
the duration of their studies.
