Our registrar is Entela. I have been satisfied with their performance thus far. They are responsive to our questions, and the auditors are (for the most part) pretty competent.
I have noticed some inconsisitency between auditors, as far as interpretations.....i guess this is to be expected to some degree. I know of a company.that uses AQA..I know this company intimately, (not my current employer).....AQA registered them (ISO 9001), with no non-compliances..I found this incredible, sinc the company is wrought with problems. Makes me wonder how thorough the auditors are. FYI
