"Mary is so knowledgeable about everything she does. I have had botox before and never have good results. Mary is the only one that really listens to me and understands what I would like and what I would NOT like, and she delivers with perfection. It’s refreshing to have that kind of trust in someone. I am not interested in ever seeing anyone else for my face! Thank you as always Mary!"
