I wish that everyone's doctor could be as informative and thorough as doctor Gainer. He does an excellent job of answering questions I have about my condition and makes me feel completely involved in his plans for my care. He always reviews with me what we have discussed to be certain we are on the same page. When I leave, I am confident doctor Gainer understands my issues and is giving me the best possible car.
