Sutherland Shire's Chartered Accountants | Gymea | Miranda | Caringbah | Sutherland |

Director Mike Trehy established the practice in July 2008, out of a desire to see local smalland medium sized businesses develop and grow through sound, proactive and value-adding advice and service.

In addition to the usual financial accounts and tax returns, Hadlow and Trehy Chartered Accountants can help small and medium sized businesses with advice on strategic structuring on to growth and  through to succession planning or sale. 

"We place a strong emphasis on identifying the business needs of our clients, and providing them with practical advice and services to meet those needs".

We also know that sound business management demands accurate and timely financial information. So we place a deal of importance on keeping your financial recording systems efficient and accurate. We cater for online accounting (cloud based) solutions such as MYOB and Xero to achieve this.

This means we can establish and monitor Key Performance Indicators on a regular basis. It also allows us to ensure that your financial statements and tax returns are completed on time, every time.

If you're an established business owner looking for a new accountant, come and have a chat with the Director, Mike Trehy, and see for yourself how easy and beneficial it can be to have us as your business and financial partner.
