testimonials — Personal Concierge Co.

“In the age of the side-hustle, many have decided that "anyone" can be an executive assistant---this could not be further from the truth. In fact---in my experience---very few have the temperament, organizational abilities, and people-skills needed to be an effective EA Heather is one of the exceptions. A good EA is able to wear many hats while still learning how to put even more on than they started with---a perpetual learner, if you will."
