"This was my first time seeing Dr. Greathouse, and I really liked him. He was personable, very thorough, and clearly quite knowledgeable. He took his time with me, and he explained everything very clearly. He ordered what I consider an appropriate test and a follow-up appointment, and made it clear that I am welcome to contact him with any concerns or questions."
