When you invite someone into your home to help with a problem, or when you ring them for urgent support, you just hope that they follow the "CHIP" principle : Courtesy / Honesty / Integrity / Professionalism
Marc has been helping us for many years now and he has always been an exemplar of this "CHIP" principle
I have no hesitation whatsoever in providing a reference for Marc and a statement of thank you for his ongoing adherence to the personal and professional values demonstrated by the "CHIP" philosophy
