"Through my previous experience/interactions with you at DAQ, I recognised that you were very professional and capable in the way you did your work.
The service you have provided is of a very high standard. I have to produce board reports and training manuals, and I want them to represent me in a very professional way and also to provide documentation for my clients which are also of a very high standard. The work you do for me, projects this image of me. I value this very much.
Lisa is a very capable and competent virtual secretary, she produces high quality work and I trust her with all of my important documentation."
