I would like to thank you and your colleagues at Hoopers for your sterling work.
My special thanks and appreciation for the thoroughly professional service you rendered in this complicated situation. It was only through your research I was able to locate and visit my half-brother and half-sister who, until now, had always been lost to me.
Thank you and your team most warmly for the excellent work you've done in tracing the family members.
It was with considerable surprise and pleasure that I read your letter. May I compliment you on your very professional presentation. I have no hesitation in signing for your commission in appreciation of your skill in tracing and detection.
