The core of the Diller teens year-long program is the summer seminar in Israel. During the three-week seminar the Diller teens went on a Leadership survival hike in the Negev desert, performed community service projects in northern Israel (a carnival with children who recently immigrated to Israel from Ethiopia and, a painting of a community center in the north), and met with their peers from the Manhigut Esreh program in Etzba Ha-Galil to learn about various issues concerning Israeli society today.
