O’Brien Plumbing Toowoomba is a family-owned and operated business that initially traded as Williamson Brothers. Ian and Peggy Williamson took over the plumbing business from Ian’s father well over 40 years, which makes O’Brien Plumbing Toowoomba the oldest plumbing company in Toowoomba.
In 2008, Peter and Mary-Lou Coorey purchased the business from Ian and Peggy. Then, in 2013, we became a member of Laser Group’s national network of plumbers and electricians. When O’Brien Glass Industries acquired Laser Group in 2019, the business rebranded and is now proudly trading as O’Brien Plumbing Toowoomba.
