    Mr. Parker really listened to what I was asking or saying and answered my questions in understandable terms. He took the time to show me various types of CPAP masks and explain about each of them. I'm not thrilled about the idea of having to use CPAP and his willingness to explain things to me helps to calm my anxiety about this. I really appreciate the time he took and the concern he showed! I feel better informed and more prepared to continue with this plan of care.
