    Dr. Mertens is always very attentive. She is extremely knowledgeable about her craft and she has a lot of empathy and compassion and her way of doing things has changed my life and I think that even though I have a chronic illness, I know that I'm being taken care of in a proper way. She's extremely, extremely generous with her time and I appreciate not only Dr. Mertens, but her whole team. They are excellent.
