Toowoomba's largest accounting and financial services firm, Power Tynan, has expanded following the merger today with local firm Calibre Accounting.

The firm's financial services arm, Morgans, will also be boosted as Calibre Accounting's associated financial planner, Optimas Financial Planning, joins the new team.

Staff from both firms have moved into bright new offices at 618 Ruthven Street, next to the City Library.

According to Power Tynan CEO Paul Hilton, the two firms share a strong culture and focus on relationships as trusted advisors to clients.

"Calibre's founders and Directors, Keith Saunders and Suman Chowdhury, will play leading roles in the merged firm and their staff will add significantly to our resources and capability to services all our clients," he said. " Ryan Myler of Optimas will add great value to our Morgans financial services arm."

Keith Saunders said: "This move is a good fit for both our clients and staff, offering a path to greater service for our clients into the future."

Power Tynan was formed in Stanthorpe in 1969. Today, the firm's head office is in Toowoomba and it maintains offices in Stanthorpe and Roma. The firm has grown to become a comprehensive financial services organisation, offering a complete range of accounting and business advisory services, SMSF administration and mortgage broking. It also provides financial planning and stock broking services through its Morgans franchise, the Darling Downs office of the well-known Australia-wide financial services and stock-broking business.

Calibre was formed by Saunders and Chowdhury in early 2010 with a focus on small to medium business enterprises in a variety of industries including primary production, professional services, retail and manufacturing.
