Exceptional Service & Unmatched Expertise. I cannot speak highly enough of Wilson & Associates Chartered Accountants. From day one, Wilson, Mary, and the entire team have been an absolute pillar of support in managing and streamlining all aspects of my financial affairs — across my companies, Trusts, and personal finances. Their depth of knowledge, attention to detail, and genuine care in their approach have made a complex landscape feel simple and manageable. They’ve guided me every step of the way with clarity, professionalism, and a level of dedication that’s truly rare in this industry. I’m incredibly grateful to have met them and feel reassured knowing I have such a capable and trustworthy team behind me. I look forward to a long-term partnership and highly recommend Wilson & Associates to anyone seeking expert accounting and financial guidance.

My husband & I have had a couple of accountants over the past few years & recently after much research we found Wilson Duong & his associates. From our first point of contact to sending through our tax details , Wilson & Mary showed us the professionalism & attention to detail that we have been looking for. Our first meeting with Wilson made us incredibly comfortable & his easy approach to working with numbers made it truly easy to understand making what we found stressful in the past disappear. We have had additional appointments to work on our plan to move forward & we feel we couldn’t be in better hands with Wilson’s knowledge & expertise , we highly recommend his services & his down to earth approach is very impressive.

Wilson and the team were such a delight to work with - responsive, knowledgable, efficient and patient when it came to clarifying our queries and helping us resolve different matters. Especially given that I'm currently located overseas, they were really accommodating when it came to communication channels, updates and providing the advice and services we needed. Will definitely work with the team again in future and happily recommend to anyone needing accounting services.

Wilson and Associates has been associated with Venture Care Support Services now for just a few months, and we have been very impressed with the service received for a number of reasons. The most important reason was responsiveness. Every question or request has been dealt with rapidly and effectively. It gives us confidence that they are genuine in their desire to provide a top grade service. When we have made difficult decisions that require tact and confidentiality, Wilson and Associates have responded in the appropriate manner, once again reinforcing the confidence we have in the organisation. Wilson himself is softly spoken, thoughtful and considerate, and is able to give a burgeoning company some gentle nudges in the right direction. Wilson and Associates are a high class company and I would recommend them to anyone in need of their services. I don't normally leave reviews, especially 5 stars, but have no doubt, this one is well deserved.
