Isaac is a graduate of the University of King's College, where he studied Classics and Religious studies. He was raised in the Parish of Seaforth and has been an active lay leader at the King's College Chapel and at Trinity Church, Halifax (an historic "daughter-church" of St. Paul's). Isaac has a deep love for the liturgy of the Western Church, and in particular how the Anglican Church has received it in the Book of Common Prayer. He is also an avid board gamer and musician. Isaac is married to Alison Kitt-Grainger.
