Dr. Grierson is the best physician I have had the privilege to have as my physician. He is so approachable, listens to everything you have to ask/say, very thorough in his taking your history.... Honestly, I have not had such a comprehensive exam, asking questions regarding every aspect of my health history, family history and concerns. He is wonderful.
