About Us


In 1963 Allan O’Brien, a toolmaker by trade and one of the leading toolmakers in Australia, started his business in a suburban garage in Gladesville, Sydney. Whilst establishing his business Allan and his wife, Norma, lived and worked from this garage to build a family home on the same property and raise their three children. O’Brien Engineering today is Australian owned and managed by second and third generation family members.
