He has had a lot of laughter, surprises and dilemmas on his journey of interfaith cooperation and bringing positive experiences of diversity to over 100,000 young Australians. He is still a Hasidic Rabbi teaching bible study at Chabad House North Shore in Sydney. He was ordained as a Rabbi after study in the UK, Australia and the US, and completed a Graduate Diploma in Education with the University of New England, Armidale.
