About Us!

O'Brien Engineering started in 1963 at a garage in Gladesville, a suburb of Sydney. Allan O'Brien, a toolmaker by trade and one of the leading toolmakers in Australia, was the founder of the company. He lived in the garage with his wife, Norma and their three children. They built the family home on that same property.


O'Brien Engineering is still owned by the family and  has over 20 employees. Head office is located at Silverwater, Sydney and houses Sheet Metal Engineering. The company expanded - the Manufacturer/Distributor division was started to complement the Engineering. Another branch of the Engineering is located at Berkeley Vale, a suburb of the Central Coast approximately 90 kilometers north of Sydney. 

O'Brien Engineering is a major supplier to the Trophy, Engraving & Identification Tag Industry with a vast array of designs and materials.
