    I am so thankful for Dr. Mendenhall and her care team. I always leave visits with her feeling more confident and positive about my health. She has an excellent way of explaining things and answering questions. She even provides helpful information for concerns and questions I didn't even know I had. I am very grateful to be in her care!
