Dr. Baddley was very knowledgeable and direct regarding my treatment. I felt I was getting a direct answer rather than the vague responses I usually receive. I appreciate his advice and no nonsense approach.

We really enjoyed our visit with Dr. Baddley. He thoroughly reviewed my test results and was prepared to have a very honest and open conversation. He carefully set the stage for my visit and asked if there were any topics that should not be discussed in front of my spouse.
