[Mike] is a man who will logically see the evidence in a case and who goes beyond the clock to do all he can to help out. You are more than just a case to him.

- 'G'

Through his investigations he saw things and found evidence in the case that my lawyer hadn't, in fact two key pieces of evidence were all his doing. As a result it took the jury less than 15 minutes to acquit and enable me to get my life back.

- 'G'

He tracked down witnesses that the police had ignored and was even able to uncover evidence that had buried. Were it not for all of Mike's hard work and expertise, I am certain I would not have had the not guilty verdict that was returned.

- 'G'

In less than 2 weeks he obtained a half dozen sworn statements that led to dismissal of criminal charges that had been pending for over a year. My only regret is that I did not hire PI Sabin sooner.

- 'E'

He came with an open mind, worked smartly, effectively and very efficiently to compile every piece of evidence for our matter, within two weeks. He was very organised and communicated well, always being available to walk us through every step of the way.

- 'I'

His investigation established it was in fact accidental and showed that the police had made assumptions and conclusions that were not supported in evidence. It was huge relief for our family to have answers to the many questions we had about how he died.

- 'K'

Charged with a crime he did not commit, Mr. Sabin was able to obtain statements from connected parties that resulted in the dismissal of charges prior to trial. When the police refused to investigate solid challenges to the charges, Mr. Sabin worked his magic quickly, efficiently and effectively.

- 'M'

They investigated my case tirelessly and with such commitment to facts and the truth. Right up until the end of the trial they were working so hard to expose the holes in the police case and show what the facts actually were.

- 'S'

Even during the times when we felt so helpless, we could reach out and feel reassured that we were in safe hands and that someone believed our boy. As the trial approached, Mike worked closely and tirelessly with our son and each of his witnesses to prepare us thoroughly.

- 'S F'

Mike's expertise, ethical approach, and logical thinking were exactly what we needed. He was able to quickly clarify the circumstances surrounding the attack and worked tirelessly to gather the relevant documents and official statements and evidence.
