Dr Ruddy was a pleasure to see even though I've been struggling because my nasal pillows haven't been secure. I have not been sleeping well. In talking with Dr Ruddy, he emphasized that I am doing well, all in all, in terms of apnea events. I went from 77 in an hour to under 1. He listened and also made suggestions. We agreed upon a mask fitting which I got later that same day, which made all the difference. I feel supported in my efforts to address my sleep apnea by Dr Ruddy. He takes a keen interest in YOU, in what's going on for YOU, and offers both support and his best knowledge. I'm grateful.

Dr. Kram was very helpful interpreting and explaining my sleep data. He was especially helpful in his observation of my peculiar odd sleep habit and recommending a different mask. As a new CPAP user, I was unaware of the differences in masks and I think his prescription will improve my sleep. My only reservation was that he seemed pressed for time, even though I was on time for my appointment. I only saw him for 15-20 minutes, which was a little short considering this was my first visit with him. I had a few more general sleep questions I would have liked to discuss. But he did answer all my principal questions and improved my understanding of CPAP.

I went to Dr. Kram because I was waking up early in the morning and noticing that I wasn't breathing. Since I have used my current APAP machine for more than five years, he recommended that we replace it rather than go through a sleep test. I felt this approach was a conservative one and one that made sense. No sense doing a sleep test if one is ultimately needed. If this doesn't work we can do the sleep test later. Also because I am going to Japan and taking my APAP machine with me, I needed a note from Dr Kram explaining why I needed the APAP otherwise the Japanese government wouldn't allow me to bring it into the country. The note was signed by him and emailed to me before the end of the day. That was great service.
