The Best Accountant that I have ever had. I have no problem referring more business to MD Trimmer & Co. In fact, I quite often go out of my way to make referrals. I speak very highly of the service that MD Trimmer & Co provides and then there is the referral program that rewards me for making referrals, AND the new client who responds to the referral


MD Trimmer & Co have dealt with my taxation for approximately the last 10 years. Before I was using accountants in my local area and found they weren’t doing all they could to help me with my tax matters and returns. Since changing to M D Trimmer & Co Mark has provided good direction on all my tax concerns and goes the extra effort to maximise my tax return.


MD Trimmer & Co have dealt with my tax for 2 years now and I couldn’t be more happier! they are a great team! lovely people! I will definitely go out of my way to recommend Mark to everyone! Thank you!


MD Trimmer is my saviour. Taxation has always been a confusing ordeal to me until I met Mark. They are always glad to help and ready to give professional advice any time. I applaud –and highly recommend– their excellent service.

I have been with MD Trimmer since 2002 when I moved to Sydney. My sister who used to live in Parkes recommended them to me. Mark and his team are very trustworthy and reliable.


MD Trimmer do our end of year returns for the ATO. Service is quick and accurate and Mark performs that “extra” you hope your accountant will provide – some good business advice and suggestions.


It was close to perfection, a smooth transaction. It was all done through phone conversation and email and yet it was realy hassle free. I look forward to hiring their services again.


We have used this firm for many years now and find it to be excellent service and value for money.


Customer Service, Offerings, Quality, Timeliness. Great service and well looked after as usual.
