Exceptional knowledge, dedication, and care. Dr. Kram and his team at C.C.S.D. are the most supportive and comprehensive professionals I have encountered in sleep medicine. The staff are always friendly and efficient, getting authorizations quickly, and scheduling appointments conveniently. I have recommended Dr. Kram and C.C.S.D. to many OSA patients.

Dr. Ruddy has always treated me with respect. He listens closely to what I have to say and discusses options for treatment. His appointments generally run on time yet he takes the time to LISTEN. I find this refreshing and notable.

The last visit was to "read" the results of my Air Sense 10 CPAP machine over a period of time. The information received from Dr. Kram was enlightening and confirming.

Aiko is extremely thorough in reviewing my chart. She goes over my chart in its entirety. She's very pleasant and patient. I was late because I went to the old office. She still allowed me to keep my appointment. Cynthia H.

Very professional. Dr. Kram explained sleep disorders and the different treatments. The night of the sleep study, the tech explained what was going to happen and what to prepare for. I would recommend California Center for Sleep Disorders and Dr. Kram.
