Dr. Hagaman was very knowledgeable and professional. He displayed genuine concern for my Issues and was motivated to find a solution. He spent time both before and after testing to describe what his thoughts were for ordering the tests and then after to go over the results thoroughly and to confirm my understanding of his plan.
