Sleep Medicine Doctors - Emeryville, CA

"Dr. Cooper is cold, booked out three months for any type of visit, and most frustrating, impossible to contact. It typically takes me a dozen calls over weeks to get in touch with her even for simple questions, like whether an appointment is in person or remote. Most recently, she was totally unreachable by my insurance company, or me, after I had a procedure she prescribed. My insurance needed some notes, tried to contact her three times, and without being able to reach her, sent me a thousand dollar bill. She doesn't pick up the phone, for me or for hospital administration. She is the single worst doctor I have ever worked with, I have no idea how she still has a position. She is known by sleep techs around the bay as "the dragon" and she lives up to the title."
