Dr. Gilliam and her nurse, Grace, were absolutely perfect, not just in their thoroughness and their professionalism and their knowledge, but just how absolutely, what a calming effect they had on me, and I'm going through a really tough time in my life, and I really needed to have that type of care. And I'm trying to keep from crying while I'm doing this. But everybody, the front office staff, everybody was just a delight. And I'm so glad. I've had Dr. Gilliam for a couple of years. And this last visit, she really helped me out on a personal level. I'm very thankful.
