“We just wanted to thank Simon and his team at Simon Diab & Associates for their support, professionalism and reliability. Simon in particular for defending us in court. It was a traumatic time for me and my wife and when Simon took my case on, I felt relieved and in safe hands. Simon guided us throughout the process explaining each step of the way. It was important for us to find someone to rely on and trust with our lives and financial matters. We won the case thanks to Simon.”
 -John & Esther from North Sydney. 

“I was a bit reluctant to use a solicitor given my previous experiences, however, I used the services of Simon Diab & Associates and I was pleasantly surprised. Simon and all staff were friendly and my matter was resolved timely and smoothly. It was a good experience and I got great results, even more than what I expected. Simon was clear and upfront about the fees and costs which were fair and reasonable. I’d highly recommend Simon to all my family and friends.”
