I’ve passed your business information along to our CEO. I understand your feelings regarding working on a panel for the scheme agents and my first impression is that because we’re not one of them, you could be a great fit with us.

If you need help, I do have a degree  B.Sc Hons (Maths/Chemistry) + Dip Ed degree, taught Maths for 10 yrs F/T, started my own business, 25 yrs go, franchised it & sold it off (as a quick summary….) I’m very good on the phone, as my whole business was ‘sales’. And I hate people(or animals) being hurt or ripped off.

After all this my husband STILL tells me they are only friends, even showed me the plane tickets, that clearly showed that from Singapore both of them went to different places. But…. it is just too late for that, I am tired of being sad and depressed all the time, and need a new fresh start 🙂 Gutted now, will get better soon:) Thank you for everything. Wishing you and your family all the very best. Kindest Regards,

  • Dear Warren, I want to thank you for your professional help. Three of the four charges against me were dismissed yesterday and the Complainants were called liars by the Magistrate. Although your analysis of the video was useful to me personally I was unable to get it in front of the Magistrate. In the end it wasn’t necessary. The Magistrate was scathing of the complaint and the police investigation (or lack off). Obviously the Magistrate’s comments will give you comfort in stepping up to testify to audio edits. Let me know what you think – and once again thank you for your work,

  • Lachlan, Yes, I’d like to visit Australia one day and experience the climate, desert, outback, and the east and south coast cities. I understand that ***** has a character all of it’s own. Here’s a quote: “I engaged Lyonswood to track down several long-lost Australian relatives. It was a complex brief and I didn’t have a lot of information to go on at first. I found Lyonswood to be very discreet and sensitive, tactful and patient, thorough and professional in their enquiries, always keeping me up to date with progress, and thinking outside the box to try different angles whenever we got stuck and coming up with results each time. I initially chose the company because of it’s reputation for integrity and for championing high standards with the Private Investigators industry, and I’m very glad that I did. My life has been transformed by their ability to reconnect me with the other half of my birth family. The day when they tracked down an internet photo (that I would never have otherwise located) that showed my half-sister looked just like myself, was an emotional one for me. Here’s to the Lyonswood guys and gals. Thanks so much.”

  • Hi Lachlan, When I first rang your firm I felt very nervous. Your office lady made me feel at ease – helpful, polite, very well mannered. I spoke to you about my problem in detail, you explained what can done and what was needed from me. E -mailed it off, within 3 days an E-mail arrived, containing everything needed and in such detail. FANTASTIC. Again in Jan this year I contacted you again on something urgent with time frame 48 hrs related to my previous matter. Before I knew it I received 5 pages of information that far exceeded anything I thought possible. Plus in that time frame in such detail and so accurate. I was totally amazed. It allowed me to go and see the person in ****** and discuss problems over lunch. Thanks to all your efforts and your staff. So please accept my deepest thanks for all your efforts on my behalf in these matter . Yours sincerely
