    My revocation of permission to do their study
    Kevin W.

    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.

    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.

    So my doctor insisted I do a sleep study so I went. The appointment process was improved and they…read moredidn't require a deposit now. The lady was very nice who did the study, BUT, she insisted that I do at least part of the study sleeping on my back. Due to psoriatic arthritis pain, I NEVER sleep on my back and I know that when I do, I snore like crazy. So I told her I didn't want to sleep on my back, because I never do...that would be false information for the test. She insisted. Sure enough, my doctor gets my test results and it says that I had sleep apnea 72 times in the night and they recommended I use a CPAP machine. I told my doctor this and he reads further and the results say that my oxygen level never dropped which is highly unusual if you have sleep apnea. So he's going to send me to a respiratory specialist to confirm. Then all of a sudden, this CPAP provider calls me and tells me my CPAP machine is ready to be picked up. I explain what happened and ask who ordered it and they said that Sunset Sleep ordered it! Now I have to assume that they're getting some kind of kickbacks for diagnosing people with sleep apnea and making them get CPAP machines. This is definitely a scam place.

    I have had 2 visits to this sleep clinic. 1st trip I was greeted by Debbie the tech in their…read moreprevious location. She wired me up, all the while chatting with me, making me feel comfortable. Explaining what we were doing & had me view a short video. From that study I learned that I still have mild Apnea. A test in 2009 where I used to live had the same result only that study was followed up by a pulmonary dr & he blew my issues off w/a simple: loose 10 or 15 lbs & I'll be fine. At that time I was 5'6", 133 lbs, so I have no Idea where I was to loose weight. Anything less & people would ask me if I was sick & that I shouldn't loose any more weight. I was disappointed & have spent the last 9 yrs rarely sleeping the 6-8 hrs my drs insist I get. My 3 cardiologists agreed that it's hard on my heart & hard to loose the now 20/25 lbs I'm over my proper weight. Last night I arrived at the new location where a tech named Romero greeted me at the door. He like Debbie was welcoming, professional & did a fab job. I slept the whole night other than 1 or 2 times I woke briefly; falling back to sleep easily. In about 1 week I'll be contacted for an appt with the med supplier for a fitting & to receive my CPAP.

    Dr Gagne has allowed me to go to the dentist without fear. I had many cavities as a teen and…read moreexperienced many nerve hits that were traumatic for me. Every visit previously had days of anxiety prior to the arrival and extreme discomfort during operations and sometimes cleanings. Dr Gagne offers many options to put you at ease and even sedate you for major operations. I have had many procedures replacing my old amalgam fillings under mild sedation. I put in earbuds and turn on some tunes while he does his work. He has always taken me seriously when I asked to make sure he numbs me really well. I would rather have my face numb than feel a thing. I am happy to say I haven't felt any of the pain I remember during operations of my youth and I no longer have the amount of anxiety I had before and during my visits.

    Dr. Gagne is an amazing dentist. I have always had a fear of the dentist since I was a child and…read morewhen I went to his office everyone made me feel so comfortable the nurses are amazing and the DR. Is great! He explains everything to you and let's you know what he will be doing, and he just makes you feel better and helps to calm you down. He deals with so many patients that have fears of the dentist and so he is very amazing at making you feel completely comfortable there. He also is very generous,and has helped me out since I don't have insurance he was willing to waive a fee for me. I strongly recommend this dentist, you will not regret going to him!!!

    For now I will give it a four star. Bad with names and I believe my sleep analysis was Elsie..She…read morewent above and beyond to make me comfortable and would recommend her to anyone that has to go through this study, (this is my third in around 8-10 years) . So many wires , a different bed, and so on. She did go out of her way to make me comfortable. I do want to say as someone that is overweight and in her 50's that the bed was pillowy soft. Makes it hard to move freely or about when u sink into the bed. Would suggest something a little more firmer bed for the company. One thing that has changed since covid day is that the machines are not humidified.. U will be a little cotton mouthed! I'm not sure how that affects the study ...' My biggest complaint lies in that I was not sent an individual result of the study results. They were sent to the specialist that referred me to them but so far not to me or my primary. I will update this review , change it or whatever when I actually sent my analysis

    I would like to give them a minus score. I was scheduled for a sleep study over 6 weeks ago. Had…read morenumerous calls from them to confirm this appointment., including today! I made many accommodations to attend this appointment and showed up at the appointment time and no one was at the lab (office) for the study. Was supposed to be all night, made special arrangements because of this and no one was there. Called, spoke to a service tech who works for this company and she couldn't get in contact with them, or anyone who could help. This location is secluded and it is night time. What an awful experience and I am sure they will do nothing for me. If it were me that didn't show for this, I would be charged an exorbitant amount of money, but they will only say sorry.

He was the best surgeon there is to repair the hernia. He also secured my stomach so that it wouldn't move up again. I very much appreciate his kind manner and explanation of the surgery and after care. I have and would recommend him to anyone with this problem. The office staff were pleasant and efficient. Thank you Dr. Billy for your care. Michelle D.

    You can't find a better doctor or surgeon in the country, I'm absolutely convinced. Dr. Billy…read morereally cares about you as a patient, but more importantly, as a human being. His superior knowledge in the field and in the operating room instill patient confidence and respect. The personal connections he establishes really make you feel like you're a part of his team and you're all working towards the same goal. I have a difficult time conveying this sense of trust and importance in a mere written review, suffice to say you won't have any regrets and your quality of life will increase a hundred-fold. He's absolutely the best doctor I've ever encountered both professionally and personally. His staff is amazing as well and they also operate as professionals with that personal, caring quality. I can't recommend Dr. Billy and his staff highly enough!
