He graduated as valedictorian from Ramallah Academy in 1968, after which he took a special course on teaching at Birzeit University. He then taught at the Greek Orthodox School in Ramallah for three years. Father Dahdal emigrated to America, where he received his BA degree from St. Vladimir Seminary in 1975 and received an MA in Theological Studies in 1977. He was ordained as deacon at St. George Orthodox Church, Washington DC in the same year, and closely following that, was ordained as a priest at St. Mary Orthodox Church of Yonkers by His Eminence Metropolitan Elia of Hama, Syria.
