This company has always been polite, courteous and on time. The place is a little hard to find. They don't always answer the phone but I leave a message or just simply call back. Extremely Satisfied with there services and products. read more

Pros: 1. Most of the staff were polite and knowledgable. 2. They had a long wait but then were able to schedule me sooner when they had a cancellation. Cons: 1. Room was dusty - see attached photos - especially in the corners and around the bed. I had breathing problems just being in this dusty room. 2. At night staff kept talking in a full voice, rolling metal carts all around and slamming doors and cabinet doors whole night. I had to ask them to stop and they said they can't. No effort to keep things quiet, which disrupted my sleep unnecessarily. 3. Restroom is on the other side of the building and if you have to use it at night - you're walking with all lights fully on! They do not dim the hallway lights at night which will wake you up. Lights should be dimmed or use red light. read more

I went to Premier Sleep Diagnostics on the night of October 3rd for apnea retesting. I have been on CPAP for over 15 years. I was informed right from the gate by a lady named Mae that I may not qualify(?) even though I have a long history of sleep apnea. In the middle night I became unable to breathe and my blood pressure shot up. I requested a CPAP machine which Mae refuse because she said I didn't "qualify". What do I have to do? die on the bed to receive help? I immediately started pulling the sensors out and Mae screamed "do not break them as they are expensive" I responded saying lady my life is expensive and ran over here to emergency at St John's where they documented my blood pressure at 214/114 from where I'm writing this. read more

Don't do business with Premier Sleep Diagnostics, if you are given a defective machine, but you explicitly revoke your authorization to do the study, they will rudely dismiss you, ignore your letter revoking authorization, claim sufficient data was collected, and then attempt to collect payment and send to collection. Long version: i went to get sleep equipment in March 2021 for a study, I followed the instructions to the letter, but the machine failed to signal data collection success. When I called them the next day, the man I'd spoken to the day before blamed me for the failure, and said I would be charged if I wanted to repeat the study. I returned the machine later that day, and explicitly revoked authorization for them to do the study, both verbally and in writing. They are now attempting to collect, claiming the machine recorded enough good data, which again is not possible because the machine never indicated data collection success, so you can add to their rudeness, and failure to follow a patient's revocation of authorization instructions fraudulent behavior. They insist that they will attempt to collect money, in which case I will take this to the Better Business Bureau, and the California consumer protection agency, which is my right as a consumer who has been wronged by a for profit business. read more

Premier Sleep Diagnostics - My revocation of permission to do their study - Sleep Specialists Near Me - Oxnard, California

Hung up on twice. Their "hold" is just to hang up. Really unprofessional outfit. They seem understaffed but don't take it out on me.

I was referred by Dr. Richardson for a sleep study due to my CPAP dieing on me, Cynthia who helped me at time of scheduling was very nice and provided me great info in regards on what to expect, facility was a bit hard to find for some reason gps sent me to back of building but overall great experience. read more

I got referred to Dr singh to do a sleeping test And Cynthia she the one who help me fill out the papers got my test done read more

I was referred to Premier Diagnostics for an Urgent Sleep Study. After reading the reviews, I was hesitant to do an overnight study at this facility. I really needed this test, so I took my chances. I was scheduled with a very nice receptionist, whom was able to get me in the same week for a study. The night of the study, I was able to park right in front. The parking lot is lit up, not too dark. The staff was nice , the bed was comfortable, I was also able to get extra pillows. I was super nervous unsure what to expect. I did have a hard time sleeping, only because it's out of my comfort zone, but did get enough hours needed for my test. The facility is clean, a bit outdated, but definitely clean. I would definitely recommend this Sleep Center to anyone that needs a sleep test. read more

Great place! Staff was very friendly Cynthia was also very helpful. My doctor got my report very quick. I also got my cpap machine witin 3 weeks. Definitely recommend coming here! read more

I have tried for over 3 weeks to get into a sleep study here. They wouldn't even reply to my emails (see attached screenshot). I finally called today and asked to speak to the office manager. Cynthia who picked up the phone asked for my name and then put me on hold. She retuned and said the manager wasn't expecting my call and that she would take a message for him. I asked who the company is owned by, and she told me the office manager (who wouldn't take my call because he wasn't expecting me) She then said he was also the CEO. So, this is how they run their business. Anyone who runs/owns a business and hides from phone calls obviously has a lot of people upset with them. You can see from their reviews on here that it's a horribly run organization. I have attached my email chain with them for you to see, where they did not reply to ONE email! Nobody appoligised. Nobody accepted responsibility. The owner/manager hid behind his secretary lol. Take your hard earned money and spend it else where. read more

Premier Sleep Diagnostics - Email with no reply for almost 3 weeks! - Sleep Specialists Near Me - Oxnard, California

What a horrible place. Dr. George Yu is the medical Director. He doesn't train his staff so the person who books the appointments has no idea what the techs know about or do. I have been there 5 times. The sold me a very expensive V PAP after my first visit. The mask didn't fit. I went to Dr Yu's office where he gave me a mask but I had to find and order the head gear on line. He said it should cost $10 or so. The head gear lists for $40. Out of touch much Doc? He offered a sleep coach. When Amy booked the appointment I told her I only had one question and was assured by her several times that the techs were well trained. And that they knew the answer. The techs response to my question was "I don't know. I don't work for ResMed". The then turned his back at me and walked away. Warring a mask I asked him not to walk away when I was speaking to him and he told me not to raise my voice and said "you can leave now". This is pure bullshit. With the minimum knowledge of the product and no desire to learn this big heavy tatted dude has a problem with listening and dealing with exhausted. customers. He was very defensive. I previously spent 12 hours online with ResMed, the supplier, nationwide and with the app developer and got no answer. Are you serious? Go simewrlse? read more

Staff is very nice and it's very clean made me feel comfortable but too much noise couldn't sleep at all with staff laughing and talking during the sleep study read more

These people don't deserve 1 star. I had my wedding ring stolen from me and they didn't return my calls for two days then told me that they were not responsible. I was stupid enough to forget it in the bathroom after my test. I asked if I could file a report and was told no they don't file reports. I don't understand how people can be so dishonest. I am goin to file a police report and will not stop until I find out what happened. read more

I only had the sleep study and will update after I get my report. I found the staff very courteous and thoughtful and attentive. I found the bed a d furniture AWFUL! The bedside and TV tables looked like they were from a thrift shift, and the bed was so saggy it seemed like it was going to sink to the floor. AND it was covered in a plastic liner, just awful for noise and sweating at night! You'd think for the prices they charge they could afford decent beds, bedding and furniture. And all the equipment by the bedside it lit up all night long. Ack! The worst night of sleep I've had images. Anyway, hoping there will be actionable information from this torturous experience! I'll say again, the people were nice and helpful. Just not a thing that is easy to do, no matter what. But the decor is blech! read more

Their billing department is deplorable. I have health insurance and the billing department said I was non-compliant, with my device, and that is why my insurance company wouldn't pay. I called my insurance company and they stated they never received a claim from them and they don't stop payment for non- compliance. They also said they did not see any notes of non-compliance. I sent my insurance company my billing statement and they said it would take up to 60 days to make the payment. I called Premier and spoke with the office manager. I explained the situation and asked that the billing department stop harassing me. Laura, from billing continues to harass me and just told me she is sending my account to collections! read more

I had my sleep study in Oxnard on 4/26/18. I chose this location since each room has its own bathroom. In the beginning I was not looking forward to it, however, the two ladies that helped me were very professional and had me feel comfortable (5 stars for both ladies). I had a bad fall just two days before so I was on 9 ibuprofen a day for the pain and took a sleeping pill that the doctor had given me to help me sleep while connected to all the wires. I slept until 3:30 until the pain from the fall woke me. With help from the staff I was able to rest until 5am. The only reason for 4 stars is because the call button at the bed did not work so there was a time delay until I could get the technicians attention to get out of bed to use the bathroom. Glenn S. read more

pretty bad, don't answer phones, loose your file, wait weeks to get the device, drive 3o mins to get it and when back home the device doesn't work. call them back and press the option on the phone service that claims i'm a doctor to get anyone on phone and they just say bring it back.. read more

Haven't even had my sleep study yet and this is already the worst experience ever. Front office called me an hour before they closed the day before my study while I was driving and told me they only accept CC over the phone or a check at the time of the service. I'd had this booked for over a month and NO ONE mentioned that. Since I couldn't give a card # while driving I said I'd call back. Now I take total responsibility for not calling back on time. But I would have taken care of this before if I'd known with more than an hour's notice that I had to do this. And who the heck has paper checks in 2022?! This is a really dumb business model folks! Step into the 21st Century! Now I can't get a hold of anyone to find out the copay amount so I can get a check from my credit union to pay for this very needed study I've waited weeks for. That's really terrible customer service guys! Badly done. I hope your techs are better! read more

Was told by the staff at the Premier Diagnostics Oxnard facility that all rooms had a private bathroom. This is why I chose this location, as I often need to make frequent trips to the bathroom during the night. When arrived for my appointment I was told that my room was the ONLY room that didn't have a bathroom and that I would have to use the office bathroom at the other end of the building. Not so nice when you're dragging a large bundle of wires along with you. When I awoke in the morning, the female technician forgot to remove the electrical contacts from my legs and shoulders. She also failed to clean up or even mention the excessive amount of electric contact grease left on my face and scalp. Good thing I looked in a mirror before I left. Bottom line, this place is NOT well run. read more

My son who is 14 has sleep study here. I was able to sleep in a pull out bed with him in room. Room was very clean and staff was excellent. The wires and things hooked up to him really made it a rough night for sleeping but was very impressed with the attentiveness of staff. Scheduling was easy and our insurance paid for study. They had coffee in the morning for me as it was off to work. Will recommend this sleep lab. Of note, not many labs in ventura county open right now cause of covid read more

They did a great job. Dr. Yu is the best. I have been going to him for years. I highly recommend them.

This place is one of the most un organized company that I have ever dealt with. They wrote my ohine number down wrong and when they didn't get ahold of me for confirmation they cancelled my appoint which I went to at 10p at night. I was told due to their mistake I would get a call first thing in the morning when the business office got to the office; well that has been over a month ago and still no call yet....now to top it off they informed my doctor that I cancelled my appointment and didn't reschedule. Lucky enough for me after no return phone call for 24 hours I informed my insurance company and they gladly changed my referral to another company and still not waiting for this place to finally call me back. read more

So far so good. Paperwork filled out. Let the sleep study begin. I've been going through this process of trying to get a study done, and finally I'm in! They hook up these monitors to study your sleep and analyze for possible sleep apnea amongst other things. The room is decently clean with a tv. We'll see how it goes. read more
