Everest Sleep Center - Downey, California

Dr. Qui takes forever to see you. I've had to wait a number of hours before being seen and this place & it is a long drive for me. Dr. Qui is not that knowledgeable and doesn't feel responsible for complications from the oral appliance. My TMJ has gotten worse from this treatment and they expect an absurd amount of $$$$ even if you don't want treatment anymore. They charge you for a full treatment but if you don't pay for the "full" treatment within 45 days they threaten to send you to collections.

Very welcoming staff and very high-tech equipment! Dr Qui is gentle and very professional in his approach to dentistry. One stop does it all, cleaning (top-notch), fillings, implants and crowns (did not have to go to different specialist for each procedure.)

This place is a scam, You pay $395 upfront for a sleep study (then they don’t want to send you your results) and bill your insurance or out of pocket of 5k+ an absurd amount. My insurance was billed and we haven’t started anything. This is a dental office looking to attract more patients by pushing unnecessary mouth guard treatments causing unnecessary weekly visits. The reviews are all 5 star because they bribe you to submit a review in front of them and they enter your name into a raffle. They push their treatment or nothing else, they stop being accountable once you decline services.

Update: Still no word or call back smh

Dr. Qiu has a great bedside manner and you can tell he really cares about his patients. Also the office staff is super friendly. I appreciate that they call to confirm appointments etc. I went in for help with my sleep apnea curious but skeptical. After getting the appliance, I went from epic snoring, Embarrassed to have anyone Sleepover, falling asleep during the day at work, while driving, at the movies, etc., to very light or zero snoring and being able to actually get the rest needed from sleep. Now I have energy throughout the day, I can do sleepovers and I can stay awake through a full movie! Life changing! Life saving actually…

If you have ever had a sleep study done before, you will likely notice a different feeling all together. I think it's largely focused encouraging at your home sleep study (not in clinic sleep study) and selling an expensive mouth piece instead of a CPAP. Quick at getting me to do an, at home study. Quick at getting the results. Quick at seeing the doctor to go over the results. Everest had all my insurance information and knew what I qualified for before doing anything at Everest. I have had sleep studies both in clinic and home. Now all they do, is send the prescription and sleep study to a provider to furnish a CPAP. I asked them last week why they haven't sent it to the provider and they said they still had some insurance to clear up. (They would not have done the study or doctor visit if my insurance wasn't verified). I asked them if they would give me the prescription and study and I would find a provider. Big pause! I'll ask if I can do that. IT'S A PRESCRIPTION! Well that was last week and we are now ending another week and nothing has been done. I let them know I had no interest in the mouth piece and I just wanted the CPAP. They want to sell the mouth piece. They have nothing to sell or gain now since another company provides the CPAP machine.
I have since had to write a letter to Everest Sleep Center:
I have been waiting for a call, text or email to pick up a CPAP and have yet to receive any contact from Everest or DME. I did sleep study Jan 9, 2025 and turned in Jan 13, 2025. I went over results with Dr. Henry Qiu on Jan 15,2025. I called the DME to confirm they had received results and prescription and they had not. I call Everest approximately a week later and they needed more time. I asked for my sleep study and prescription but woman at Everest told me they don't do that but she would ask. Not a word since. I was perfectly clear with Dr. Henry Qiu as well as his staff that my CPAP was giving an error message and had already shut down at least once. It is imperative to my health I get another CPAP and therefor will hold Everest Sleep Study and Dr. Henry Qiu liable should my health suffer in anyway which can be attributable to not sleeping.
Whether I receive a call from Everest Sleep Center or not, I will be filing a complaint with Medicare and my secondary insurance today for not providing proper healthcare. Feb 4, 2025

These days it’s very rare to encounter great customer service. Today my expectations were exceeded during my visit at Everest Sleep Center.

The entire staff is friendly, courteous, informative and knowledgeable. Pam and the rest of the staff are great. 👍🏼

Cassandra was incredibly helpful throughout the entire process. After I had issues with FedEx, she personally ensured the package arrived to my house without any issues. Incredible service, thorough follow up, and amazing patience throughout the entire process. Highly recommend!

My father has been sleeping and feeling great after everything that doctor has recommended him to get done. We definitely see a difference in his health and sleeping. He’s now sleeping 7-8hrs which is something he wasn’t doing. He would only sleep 3-4hrs and feel like he wouldn’t rest.
