Dr. Wexler is always outstanding. She doesn't just tell me what to do. She takes the time to explain why she thinks it makes sense, both from a research standpoint, as well as what she knows about me personally. Yeah, I just feel like she always goes out of her way to make sure that I have the best care and also to make me feel good about what I'm already doing. Diabetes is such a difficult condition to manage and I've had lots of other doctors in the past that make me feel bad about myself when my blood sugars aren't great. She goes out of her way to make sure that I know that even if my blood sugars aren't perfect, that's not a reflection of me as a person. It's just a really hard disease and that really does so much for me.
