Dr. Miller always makes sure you understand the outcome of tests that were done prior to the appointment. He not only explains the test outcome but makes suggestions on how I can keep improving the outcome on future tests. He is an excellent listener. I will miss his counsel inasmuch he will be retiring before my next appointment. He will be missed.
