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.

Aiko and staff create an inviting and professional atmosphere. She is always punctiual and pleasant. She answers my questons in detail and assures I have a satisfactory understanding. Likewise the staff who prepped me for my sleep study were personable. They helped me relax and feel safe in an unfamiliar sleep setting.

Staff is nice (Alameda office gets very busy but they really make an effort to accommodate everyone). I have found Dr. Kram to be very knowledgeable and attentive. At my last visit he took the time to engage me in a lengthy conversation to understand the background of my medical issue(s) so that he could, in turn, better explain and understand the results of my most-recent sleep study. He went into detail and I felt he really listened to my needs and my issues. I've been very pleased with Dr. Kram.

Staff and professionals were very courteous and knowledgeable. The sleep test and technicians are there for you to make you comfortable and answer any questions you may have to make you feel comfortable about the test itself. Yes, there are a lot of wires and plugs but nothing that will hurt or harm you. I didn't think I could sleep through all the wires, but the techs make it so that you really can't tell and you sleep right through it. These are caring folks. If you talk to them and how they all got into this line of work, they all have a story about someone they know with a sleep disorder. These guys are family there and they treat you the same way...like family. Dr. Kram is very knowledgeable in the subject matter and gladly will share his patient's results with them and explain how everything works and how the CPAP equipment works and how better it'll help his patient.
