Informality blended seamlessly with official duties as we celebrated opening our new building in late May.

More than 100 guests mingled with staff, enjoying drinks and variety of finger food, including Asian vegetarian dumplings, kataifi prawns and mini chunky beef pies.

The move to a new open-plan office came as the firm expanded and merged with Toowoomba accounting firm Calibre Accounting.

CEO Paul Hilton introduced Toowoomba Regional Councillor Geoff McDonald to cut the ribbon and officially open the building, thanking staff for loyalty and clients for their trust.

McDonald, a fifth-generation Toowoomba businessman and Chair of the Council's Environment and Community Committee, said Power Tynan was a "great corporate citizen", particularly through its Charitable Trust and school-leaver's scholarship programme.

"This is a great example of a local business doing well through giving back to its community," he said.

He joked that, with more than 20,000 visiting the local library located in the same building, the move had been astute.

"You're certain to find some new clients through that association," he said.

Guests praised the firm's work and the trust we have established with clients.
