Utilized a number I listed as an *EMERGENCY CONTACT* to call about some paperwork they were having an issue with so I cancelled my appointment before seeing the doctor, sadly. I had already filled out all the paperwork and confirmed my appointment before they contacted my emergency contact.

Wholly inappropriate and does not inspire confidence in me that this office would protect my confidential information.

Staff is atrocious, you have to bug them constantly to do their job. Their hours of work are 3 1/2 days a week and good luck getting anyone to answer the phone, let alone call you back. Too soon to rate Dr Popper but he does have the bedside manor of a mushroom growing on a log, no interpersonal exchanges, just question, then silence. It’s like getting bamboo shoots driven up nails. Hope he knows what the heck he is doing

I had three doctors confirm to me this man committed a grave error, based on his laurels I was willing to believe it was an arrogant mistake, consultation with legal representation specializing in medicine confirmed that he came within an inch of a malpractice suit. He also was involved in the death of a patient and his hearing is available under disciplinary action on healthgrades. My doctor referred me to Dr. Popper and would later relay to me his confusion at Dr. Popper's treatment. It took 14 messages over a two month period to get a callback, because he is ostensibly the only real sleep center. He immediately and erroneously diagnosed me with RLS despite me showing no symptoms and refused to listen to what my real symptoms were He ordered a blood test to verify. As I would later find out the blood test proved him wrong and showed an extremely high, dangerous concentration of iron, for which he prescribed iron pills. If it were not for my pharmacologist's suspicion and concomitant request for lab copies, I would have gone along with it. I had a hematologist, internist, and the pharmacologist look at the report and conclude he must have made a mistake (he told me my iron levels were actually low). I returned and he did not admit his mistake, rather he continued to prescribe iron pills. In this meeting he admitted that they did look higher than he had thought before, (97% according to the hematologist) but that he had actually been looking for a different measurement and couldn't find it last time, even though he was the one who ordered the lab. I ask him if I can stop taking the iron and tells me to continue without offering an explanation, some would call this gross incompetence other perhaps poisoning (his disciplinary action was because of mis-medicating that resulted in a death). It seems pointless to mention his bedside manner in the face of borderline quackery, but it was not particularly high either. I am now receiving treatment for the massive amounts of iron.

I have never been treated so poorly by a doctor in all my 37 years. First, as another reviewer stated, you have to jump through hoops to get an appointment. Fine. I jumped. Had my appointment and was recommended for a sleep study. I definitely needed it. I was in the process of changing insurance as I got a new job and the receptionist had to verify prior to the study. The appointment was sent but insurance coverage was NEVER verified. So I had no idea if I should go to the study or not. I called the office that day to verify, but they are closed on Fridays. Nice. Had the study, the technician was awesome! Had my 1st follow up. Got a CPAP machine which is fantastic! I have severe sleep apnea.

Now today I had my 1st follow up after getting the CPAP. I have already taken a ton of time off work dealing with this. I had forgotten the disk they need so I had to turn around and get it causing me to be 15 min late. They called me in, took vitals and then proceeded to make me wait for 45 min. Then the nurse came in and told me I had to make another appointment! Seriously??? They clearly don't respect patients time and I got punished for being late. My bad, I get it. But they could have told me when I came in, not almost an hour later to reschedule.

The doctor is very arrogant and has zero personality. I complimented his sleep tech and he barely even responded. The nurse is even worse. The driest personality I have ever seen! No emotion, just walks around like a zombie. She clearly loves her job. And the receptionist is there for eye candy, but clearly is lacking in the brain cell department.

Needless to say, I'm finding another doctor! One who actually shows a little care and concern for his patients.

I had two overnight sleep studies with Dr Popper. It is a one size fits all approach and you will be given the same appliance they give to every patient. If you have nasal obstruction, you breath through your mouth when you sleep, etc there is a good chance the therapy he prescribes will not work. If it does not work he is not interested in hearing from you. He will refer you to the company that sells the CPAP and they will basically just tell you what you already read in the instruction manual and tell you to keep trying. CPAP can be life changing and I am sure if the off-the-shelf set up works for you your experience will seem fantastic; hence all the positive reviews.

A life saver . Dr Popper was the highest recommended sleep specialist I researched. I had chronic sleep apnea and didnt know it. He is very professional and knowledgable and his staff is equally proficient.

Staff was polite and professional. However, at a follow up appointment on 7-28-14, I was uncertain of a recommendation Dr. Popper made. He became arrogant and condescending. I believe it is a doctor's responsibility to listen to their patients and not try and push a treatment. Very unprofessional. It doesn't matter how much a doctor knows, if he doesn't care about his patients' needs and concerns.

I have so much to say that I don't know where to start. I was very apprehensive before my first meeting with Dr. Popper, but from the moment I walked in the door everyone, from Ellen at the front desk to Lori, the nurse who took my vitals and completed my chart, to Robin the office manager, made me feel completely comfortable and much less anxious. When I met with Dr. Popper, he also put me at ease as we discussed the completed questionnaire I had submitted a few days earlier. He explained things very clearly. I never felt rushed. And I left with a good understanding of what was to come next. I'm now learning to sleep with CPAP and I cannot tell you how grateful I am to Dr. Popper and his entire staff for what they've done. I know that my life is going to change for the better when I'm sleeping well and sleeping through the entire night on a regular basis. THANK YOU to everyone at Southern California Pulmonary and Sleep Disorders Medical Center.

I had an incredible experience with Dr. Popper and am happy to recommend him and his team to anyone suffering from sleep problems. He was extremely professional and knowledgable in his approach to diagnosing and treating my insomnia and now is someone that I would have no hesitation in calling if I ever struggled with insomnia again.

Everything was well explained to me at both the office visit and the sleep clinic study. Dr. Popper walked me through all my options for treatment of my sleep disorder. I would recommend Dr. Popper and his sleep clinic to anyone suffering from sleep apnea or other related sleep disorders.
