About Us.

All businesses that wish to be successful and gain client support must come up with a Unique Selling Proposition (USP) and ‘what makes the business different” for their services or products. At Modderno & Co, we didn’t have to – because we are the USP.
In the one professional practice you have a combination of expertise and experience that covers everywhere from “what should I do with my tax matters and accounting requirements”; “how do I start and build my businesses or investments” through to “ how do we take the business to the next level”; “how to future proof the business” and “how do we get the business exit ready”.

The practice leaders’ combined expertise and experience cover creation of an idea and business structure, looking after your tax and accounting matters, building your personal wealth, growing your business profitably and sustainably as well as exiting your business with the desired outcomes.

One of our overarching promises is “we work with you for your personal and/or business success” and “if we don’t know the answer, we promise you we will know someone that does!!”

Susanne Modderno.

Practice Leader – Accounting and Tax

Susanne is a Fellow of the Institute of Public Accountants as well as being a Fellow of the institute of Financial Accountants, she also is a registered tax Agent.

She started her practice very early in her career and as such Modderno has a history of some 40 years service to her clients with 17 of those years being based in Parramatta.

As a testament to the excellent service she and the team have provided to their clients, the practice has over 100 third generation clients, this fact alone proves that Susanne can assist a family over a long period of time and across generations and can provide estate planning.

Susanne Modderno

Many of Susanne’s clients started as private PAYE then micro 1 person businesses through to multi million dollar SMEs.

Clients come from all segments of the marketplace; professional services, primary producers, R&D companies, retail, finance and investment, all manner of tradies, manufacturers, importers and exporters to name but a few.

Susanne’s communication style allows her to be as equally comfortable, capable and more importantly, valuable in dealing with the technical discussions needed to be had with the Australian Taxation Office and other compliance authorities through to layman and mums and dads.

Whilst Susanne can carry out all areas of accounting, she has a support team of accountants and bookkeepers to assist in those areas so that her personal focus can be on vision and growth strategies, estate planning management and financial accounting and all areas of compliance accounting matters.

Susanne’s belief is whether it is business or personal –“its not about the numbers if it doesn’t benefit the people.” To that end she has introduced a specific department / alliance partners to develop a valuable and trustworthy professional group for those that need to deal with the complexities of the NDIS and ageing challenges, who may be fearful of being unethically treated.
