I love working with Maria. She's the first medical practitioner I've worked with in a long time who really listens to me. I also like that she challenges me a little bit. So many doctors I've worked with just kind of nod and move along, but Maria actually engages in the conversation. When she says, "But what if we try this instead," or, "Have you thought about it this way," it shows me that my success matters and I matter.
