Rebibo was recommended by
Joseph Kaminetsky, then head of
Torah Umesorah – National Society for Hebrew Day Schools, as the best choice to open a Jewish day school in the southwestern US city of Phoenix, which then had a population of 10,000 Jews. Since most of the student body did not come from Orthodox homes, Rebibo calmed parents' fears that their children would be "converted" to Orthodoxy by setting a policy accepting children from all streams of
Judaism. In time, some of the parents most active in the school were those belonging to the local
Reform temple. A few weeks before opening day, Rebibo spotted a "
for sale" on a house at 337 East Bethany Home Road and acquired it as the school's first campus. Also in 1965, Rebibo founded the Greater Phoenix Vaad Hakashruth kosher certification agency, which he continued to head until his death in 2024. and in 2005 he led the effort to install a neighborhood
eruv. Rebibo was a strong supporter of the State of Israel and often speaks at Israel solidarity rallies. ==Family==
