"Donna arrived on time, was friendly and knowledgeable.  She didn't waste time but didn't mind answering our questions.  She was easy to talk to and really seemed to know her business.  We really appreciated her coming to our home to conduct business.  If we require a notary in the future, she would be our first pick.  Thanks Donna!"
