After several consultations, for over 2 years, Dr. Kerner advised me to have 2 surgeries to treat my Obstructive Sleep Apnea. He kept assuring me that for my condition, it was going to eliminate my problem. At the time I was using a CPAP machine to help me sleep, but him and his nurse kept insisting that the surgeries were going to cure my Apnea. The surgeries sugested by them were first a deviated septum surgery, then a UPPP with a jaw/tongue advancement). After undergoing those 2 painful procedures, not only it didn't cure my Apnea (I continued snoring, no change), it made matters worst, because with no uvula, I can't no longer tolerate a CPAP machine. After I got an updated sleep study, I called Dr. Kerner's office to bring the facts to him, but this time around his staff would not return my calls for a consultation. I wonder why??? All they cared was billing my insurance ($$$), because that they did quick. Dr. Kerner and his office showed no interest in my case after the surgery was performed. The office manager even told me that they have no record of me as a patient (Northridge Hospital does). I continue to have the same email and phone number. As far as I am concerned, they are not to be trusted. Stay away!
