Downright rude and dismissive. I did a bunch of research on doctors and facilities in the bay area and felt this one would be the most promising only to discover they're quite the opposite after one short phone call. The lady that answered asked me what my sleep issues are to which I shared that I have had insomnia for 13 years and my main issue has always been staying asleep - I wake up every night ~4-5 hours in. Occasionally I have trouble falling asleep. To which she replied, well we can't help you. You need to go to a psychologist. We can help with the former (staying asleep) but not falling asleep. So, I said ok...well staying asleep IS my main issue so I would like to go their facility. Then she asked where I am...I am in Santa Cruz. To which she said "That's too far for you to come to our facility" and I said I realize where you are and I am willing to drive an hour for great service. This is my health after all and a huge problem I'd like to solve. Then she says ok, I'll send you contact information about the doctor (or some kind of information) and she's about to hang up but I stop her to saying "Wait! How are you sending me this information??" and she said she'll text it but I was using a google voice number, not my cell. I told her that, gave her my cell number and we ended the call. Well, guess what? Never got a goddam text. Unbelievable. read more

I have attempted to set up a sleep study with AltoSleep several times. I have called their phone number multiple times with no answer. I left a message on voicemail but never got a call back. I also sent a message via email to the email address listed on their website and this also did not produce a response. I'm not sure what is going on because they seem to have received good reviews in the past, but I have not been able to get a response from anyone at this business for over a month. I can only assume that they have gone out of business. read more

Not sure if this is still a going concern... I called the phone number listed on this page several times, and it always goes straight to voice mail, with no message declaring that you have reached "Altosleep". I remember having a similar problem several years ago, where messages and emails would go unanswered for days or weeks. read more

Incompetent and dishonest. They tried to "sell" me, for cash out if my pocket, an expensive study another doc, who was a fellow at Stanford and extremely well trained, said with good reason I did not need at all They tried to sell me a machine, for $1000 out of my pocket, my insurance routinely covers 100%. They concocted a false story to justify both of these sleezy moves. I was born into a medical family, my father was a promenent physician and public health official and have an MD degree myself. These idiots tried to scam me. Are they trying to scam you? You better be concerned about that. No stars. read more

Amazing service and support, especially from Tina-Maria and Homa who have gone above and beyond to help me out! They've been very diligent with their services provided and have always helped me out with any concerns or questions I had. Even when the insurance companies took forever to respond, Tina-Maria and Homa helped to expedite the process and get me started with the CPAP machine. I especially loved the fact that I didn't have to worry about my insurance company at all, instead they handled all of it. Highly recommend Alto Sleep Clinic to anyone who may have sleep disorders. read more

These folks are truly Health Professionals! I came here after seeing a sleep Doctor in San Jose ( near where I live ) who wasn't any help at all. I drive from South San Jose to Mt. View in order to meet with Dr. Katzenberg. We had a great meeting where he helped me get to the root cause of my sleep issues. He figured out the CPAP machine I have was not set up correctly and it was an older one as well. Tina-Marie is Awesome, she did battle with the insurance company on my behalf multiple times and got a new Auto CPAP machine for me, and the insurance paid 75%, I paid the balance. Whew! She Rocks! Tina Marie runs the front office, she is so caring, smart, knows the equipment and really knows her business. She calls back, does really great follow up and she makes you feel glad that you've found them! If you are looking for a sleep Doctor, I highly recommend these health pro's, you will be glad you did, and you will sleep better too. read more

The people at AltoSleep clinic are amazing - with Homa leading the team I met. I had two sleep studies at AltoSleep - both were done professionally and compassionately. Sleep studies are, by nature, rather intrusive with many electrodes attached. But, the team at AltoSleep made me comfortable and were available to me during the night whenever I needed. Having had a previous study at home I was dubious about going to a sleep clinic - but they allayed my anxiety and were able to produce useful results quickly. When the sleep specialist MD produced a report, Homa emailed it to me (and my primary physician) and patiently reviewed all results. She then helped me to select an excellent CPAP machine and has "held my hand" as I discovered how to use it effectively. I unconditionally recommend AltoSleep for diagnosis of sleep disorders. read more

Even though I see a different sleep doctor, I get all my supplies through Altosleep. This is because all my interactions with the front desk - specifically Tina Marie - are pleasant. Other suppliers in the past have been a nightmare to work with - but Altosleep is anything but. Tina Marie made sure that the fit on my mask was correct, and lead me step by step on how to use the CPAP machine. Any questions I had were answered without even a bit of attitude or confusion. Trust me - if you're looking for a great place to get your CPAP machine and/or supplies from, this is it. read more

I have a snoring problem. I drove all the way down from Davis to AltoSleep on the recommendation of a friend who also had a sleep study performed here. It was worth it. The technician who set up and monitored my sleep study was knowledgeable and friendly. The process itself was completely painless and I slept through the night without any issues. After the results of the study were in, I was given all the information I needed to improve my sleep quality. I'm glad I let my friend convince me to get a sleep study done here, because I've been sleeping much better since. I strongly recommend AltoSleep! read more

I first went to Altosleep in 2012 after long suspecting having sleep apnea. I was very nervous; however, the staff were extremely warm friendly, professional and put my fears at ease . My results were sent to my PCP and myself and turns out i had very severe sleep apnea. Altosleep interpreted the findings, set me up with equipment and taught me how to use. 5yrs later and im still using my CPAP and feel much much better. This was life changing and only wished i had done this years earlier. I highly recommend Altosleep! read more

I've been seeing another sleep doctor in San Jose and wasn't getting the answers I wanted clearly. I called in and Tina Marie answered promptly. She communicated clearly and answered my questions about insurance and process to getting a C PAP. I'm not currently a patient, but will go here for future sleep related issues based on the quality of my phone questions being answered! read more

You cannot image how grateful I am to AltoSleep for everything they did for my mother. Since a couple years ago, I noticed that my mother snored loudly. After I read some articles about snoring, I decided to do something for her. I was so lucky that I found AltoSleep online. I read all the reviews at Yelp. Because of the impressive comments, so I decided to write an email. In the following weeks, Homa replied all my emails very quickly. When my mother visited me, I brought her to AltoSleep for a diagnosis study. Leo welcomed us warmly. He's really a nice person and very professional. He chatted with me while he's attaching tens of wires. My mother slept very well that night. After less than one week, I got an phone call from Homa. The report was ready: my mother needed a treatment study to fit a CPAP machine. My mom visited me once a long while, and her visit is usually short. So we need to get the problem solved very quick. Homa made arrangement very efficiently. She scheduled a treatment study and a visit to doctor immediately. I brought my mother to AltoSleep for the second time. This time we were not that lucky. My mom couldn't fall sleep. I can image she must be very worried that night. Because of language barrier, I thought my mother and Leo cannot communicate. But Leo was so smart that he used Google translate to translate his words to tell my mother "everything will be just fine". Both my mother and I really appreciated that. Two days after the treatment study, we visited Dr. Katzenberg and Homa to go over the diagnosis report and get the machine. We were impressed by their knowledge on sleeping problems. That visit lasted for more than two hours. It was really like a lecture to me, very informative. With AltoSleep's great effort, my mother has good sleeps with CPAP machine now. I'm more than happy that her sleeping issue finally got solved. read more

This place gives me the zzz's literally! What can you expect with a sleep center? People seem nice enough. There are jokes, however, are amazing, put me right to sleep. I guess from that perspective they are exceptional. Thanks! read more

So I knew I snored, everyone told me that. And my wife said I sometimes stopped breathing. A friend we go camping with told me to get a sleep study 4 years ago. Then, a couple of my friends got CPAP machines, and I realized I have like 10 friends who have them. So, decided that it was time. But thrashed about trying to figure out where to go for help. Eventually, my doctor recommended AltoSleep. Ok, let's try that. So I mustered my courage, and sent them an email! (so brave). I was able to get an appointment in about a week. It's weird to knock on a door in a medical park at 8 PM. Leo, the sleep tech, answered. He pretty quickly put me at ease and we chatted while he attached 30 or 40 wires to my body. The bed was a little soft, but comfortable enough. They have 2 people per night from what I could tell, and I got a pretty "good" night's sleep. I felt like I was in professional, competent hands. A week later, I got a nice report in my email and a call suggesting another study. Leo aced that one as well. Me, not so much. Homa, the voice of email for Alto, totally responded quickly and effectively also, so I was able to put together a plan of action quickly. I highly recommend them if you feel exhausted all the time, especially if you snore. read more

I have a problem with snoring. Last year, I called the clinic and went in for a sleep study. The team at Alto Sleep - Tina & Homa answered all my questions relating to insurance and costs. The night of the sleep study , technician Leo was very professional and put me at ease. Overall the experience was smooth. The room itself was very nicely done. Dr Katzenberg walked me thru the study results and gave me various options. Overall , I don't know of any good sleep labs comparable to this that exists outside of major hospitals. These guys know what they are doing and they will go out of the way to help you with care and compassion. Highly recommended !. read more

Extremely glad that I was referred to Alto Sleep. After a terrible experience elsewhere, elsewhere and elsewhere I simply decided to forget about it. That is until I got a talking to from my PCP. Tina Marie and Dr. Katzenberg made it simple and kept it on point. Let me just say I am glad I did my study with this office. I can now move on with life far more educated on what got me here in the first place. read more

So I decided I wanted to live as long as possible, and not die because of my sleep apnea, evidenced by my snoring. Now I am a powerhouse! I used to feel at 3 p.m. that I needed to steel myself for the rest of my day... that little bit of sagging in my energy. Now I sail right through and I don't even notice until 6 that it is time to wrap up my day. I don't feel that I want coffee, tea, or chocolate in the afternoon any more. Homa, Leo, Tina Marie, and Dr. Katzenberg are so caring. First of all, the office deals with insurance efficiently. (From P.A.M.F. Sleep Center, I just got a shrug, and "you will have to check with your insurance." That's why I use this independent clinic.) Recently, after a number of years, I returned for a new study etc. After taking home my new CPAP I was not totally happy with the mask. Homa said to just come into the office any time, and she had a solution for me. Of course, no extra $$ and with a smile, and "Let me know if you have any other problems because I will try to find a solution." It turns out that she has actually hand sewn alterations to the standard commercial head gear for some of her patients when there was nothing commercially available that fit! Everybody on the team has a professional and caring attitude, but along with this, everyone is also extremely competent. I am sooo glad that Altosleep now provides equipment. For years before, I had to deal with PeakSleep and Pacific Sleep, who were o.k., but there was no one there who would actually solve my problem as best as possible and tell me exactly what was going on with insurance. I used to buy my own hose, because they could not get the insurance to pay for a nice one that did not rustle at night. Now I know, in a case like that, I can just call Homa or Tinamarie, and ask for help with any problem. read more

This is an update of previous review. It took long time to schedule the sleep test is because the insurance company's slow response. Will update the review once the sleep test is done. read more

Very clean and modern facility. Allan, Leo and Homa were all terrific! From the very beginning to the very end, AltoSleep made the experience a seamless one. Allan was my first point of contact - he handled the scheduling. He had spoken to my insurance company to obtain all cost-related details prior to our phone call. He then disseminated all of that information to me in layman's terms. He was so nice! Leo was an absolute professional. It is evident that he has many years of experience in the field and is very knowledgeable. He tries to make the process as comfortable as possible and provides an in-depth explanation before he attaches the wires to your body. Homa runs the clinic and performs the follow up. She made herself very accessible by phone/e-mail and her prompt response time/turn around time is amazing. read more

I know I snored, everybody and my brother told me I snored, but I was having a hard time getting through the day without taking a nap. When I started having to take two naps a day, I knew something wasn't right. I saw an Ear, Throat and Nose specialist who was not very helpful, but that's for another review, but did one good thing and recommended a Alto Sleep Clinic for a sleep study. I was scheduled promptly and greeted that night by the Sleep Technician, who was very knowledgeable, nice and a calming influence on me. I felt like I was in a cool Sci-Fi movie with all the wires connected to me and I even got to watch a little Seinfeld before going to sleep. It was like staying at a nice hotel. Two days later they called me with the results and explained every aspect of the test and what the numbers meant to my health, they were very thorough and patiently answered all my questions. I woke myself up so many times per hour, I was shocked, to think that my snoring had made it impossible for me to have a decent sleep. Needless to say, "no bueno." So I had to go in for the CPAP treatment .There were no surprises the second time around, I got wired up and used a CPAP machine. This would allow them to see what settings I would need to sleep through the night. I took to it like a fish to water. The next morning was AWESOME! I didn't have dry mouth and I didn't wake up to go to the bathroom, what a difference...a life changer! Then the office manager Homa, really shined. She took care of all the insurance work and helped me get my own machine, which is state of the art and quiet. They have been excellent with follow ups ever since. My daughter says I'm driving her crazy because I have so much more energy than before and NO MORE naps! It's been two months now since I started using the CPAP and I have lost 6 pounds and I feel much better when I exercise. I highly recommend AltoSleep clinic. Their staff is professional, courteous and just nice people. If anyone has told you that you snore, you should get a sleep test to be on the safe side. It could change your life...it has changed mine! --Ron read more

I was referred to Altosleep by one of the top otolaryngological surgeons in the SF Bay Area, who diagnosed me with severe sleep apnea. From the moment of my first contact with Altos Sleep center, my experience has been nothing short of spectacular. Homa and Tina Marie are not only extremely knowledgeable about the equipment, they are true evangelists of sleep therapy. Being an attorney, naturally I had a lot of questions. Homa and Tina Marie were extremely responsive to every phone call and email message. And, they took the time to provide thorough explanations and demonstrations of how the equipment worked and especially to ensure that I had the correct gear and fit. They truly care about how their patients sleep. Toward the beginning of the process as the equipment was getting tuned to my comfort level, I called Tina Marie late in the working day to provide feedback. Tina Marie went out of her way to reach my doctor, and she implemented the prescribed adjustments that same evening after office hours. It's been many years since I've gotten a good night's sleep and Homa and Tina Marie have been critical to my treatment. read more

This is to update my earlier review that was not highly favorable. It turns out that the primary problem I experienced was due to the policy requested by my recommending doctor's office. Something important to others--my doctor's office wanted to take over after the sleep lab, but it was they who failed. The sleep lab has since clarified this with the doctor's office and are completing the follow-up analysis with me. What was not clear to me at the time was that the Altosleep Clinic offers only lab service and analysis. I think this gives them much more independence which is to be applauded. Another lesson I learned that cannot be explained is that somehow Medicare shorted the sleep lab on payment so I was left with a modest cost that was not expected. read more

My husband did his sleep study through Altosleep 2 years ago. From the beginning, they have been so accommodating as we navigated through every step of the process after he was diagnosed with sleep apnea, from what supplies he needed to insurance. Homa and Tina-Marie go out of their way to take care of us. We highly recommend this place. read more

Dr. Katzenberg is very welcoming, knowledgeable and accommodating, Tina Marie in the front office is just an absolute sweetheart and the guy who sets you up with the machine (sorry guys - I forgot his name) is great too. You don't feel rushed, you feel cared for, and THEY SPEAK GOOD ENGLISH! If you're in Santa Cruz, it's VERY worth the drive! I used to go to Dr. Morse in Santa Cruz. For years I took the empty promises, rudeness and ignoring from his staff. They'd tell you they were going to do something and never did. You could stand at the front desk for minutes and feel completely invisible. They'd put you on lists for automatic supply delivery and 3 months later tell you that you never signed up. Happened numerous times! I don't know why I put up with those behaviors, other than they are the only sleep center in this area that I could find. Take my advice... if you're in the Santa Cruz area and need a sleep disorder clinic - DRIVE OVER THE HILL! It's SO worth it. read more

I feel so fortunate to have been able to have a sleep study done at Alto Sleep Clinic. My doctor finally referred me there because I have been battling fatigue for quite some time and nothing else could determine the cause. From the first phone call I made to make an appointment I could tell I was in good hands. Homa is top notch. She is so knowledgeable and so helpful, I never would have expected to receive such personalized care and attention. When I arrived for the study, itself, the two techs that were there immediately put me at ease. The clinic is very comfortable, not big and imposing. I expected hospital-like conditions, but it felt more like a hotel (with how it was decorated and appointed) That really put me at ease, as well. The technicians were helpful every step of the way. I received my results, which were interpreted by the M.D., within 2 days. Homa patiently went over my results with me and answered any questions that I had. She took so much time to educate me that she even emailed me articles and is willing to help me with any additional questions that may come up later. I, unfortunately, have a lot of experience dealing with doctors and healthcare providers, and I have never received such personalized attention, anywhere. read more

Having done my first sleep study at Altosleep, I cannot imagine that any other place can up the service level I received from the staff at Altosleep. These guys are super friendly, accommodating, helpful, and very knowledgeable! Not only did they schedule me to come in very quickly, in 2 days, but the time they took to address all my questions before and after the appointment are beyond any level of service you would expect from any medical service provider. Homa is super friendly, and took the time to talk to me by phone several times prior to and after the study, going over every concern until I all my questions were addressed. And here's the kicker, after having done the study, I realized that I slept better at Alto Sleep than on my own bed, so I called to ask what type of pillow they used so I can buy the same, and guess what? They offered to drop off a new pillow for me in front of my house, and they did just that! What?? Unbelievable! I could not imagine that I would be thrilled by a sleep study service, but I truly am grateful to these guys! Thanks so much to Homa and the entire team. Other services provider should learn from this example. I highly recommended these guys! read more
