Dr. Oran was very patient with me and seemed interested in helping me find a way to make using the sleep machine less annoying and more effective for me. I really appreciated that.

Aiko Loo is knowledgeable, listens to my needs and concerns. I feel that my health and well being are her top priority. As to the sleep center web site and management, very frustrating. Hard to get call backs, appointments, long wait times for follow up. I will say Aiko is worth the frustration, but I did consider going elsewhere just because of the centers business system.
