Carla was exceptional. she was very kind, patient, and knowledgeable. She treated us like family and was very attentive to all of our needs. She went above and beyond to make a not so fun experience tolerable. She is GREAT and an asset to their organization. read more

I came to Sleep Medicine Specialist of CA from the Peninsula because the service and professionalism with my previous doctor's office was deteriorating fast. I was referred to by a colleague and it was the best decision to date. The medical assistants are professional, follow through accordingly and provide pre-COVID service (professional and caring). Sleep study appointments and follow-up are easy and convenient. My questions and concerns were answered by knowledgeable professionals (Dr. Grewal is great!). read more

Look elsewhere for a better office/doctor. I have been with this office for over 15+ years. The office tried to bill me for services that was not provided. I tried to contact them via emails as well as phone call numerous times but never return my calls to help resolve the billing problem. Tele-consulting with the doctor is always a rush and never feels I'm receiving the proper care and patient treatment. read more

Close to home, very clean and accommodating, always making sure you are comfortable. Tony was great! He explained the process and always checking in. read more

I come here for sleep studies and appointments with Dr. Singh. He's very knowledgeable and experienced in the field of sleeping disorders. Very detailed with explanations and answered all of my questions about my deep snoring and sleep apnea. Although I still don't believe I have sleep apnea, he makes me believe I do. Okay, I guess I do. whatever! :) The rooms for sleep studies are clean, some with t.v.'s with Comcast HD. The staff is very nice, and responsive. They help their clients to the fullest. read more

See all

Go elsewhere. Figured I would chime in as a recent experience. For a heads up, this clinic appears to have switched to only telehealth since CVD. I spoke with a medical assistant who barely introduced herself, I advised her no one had sent me anything after my initial conversation with the receptionist. The MA tried to bill me over the phone? I said to send me a bill. The MA couldn't even pronounce the name of my primary doctor. She also noted the main Dr. isn't even based in CA. I cancelled immediately and will find something else. Spoke with her for 5 minutes, so they better not send me a bill for a copay. This sounds all sorts of fishy to me and that they are patching the Dr. in to all these phone call appointments when he isn't even located in CA. read more

I dunno what the deal is with the previous reviewer, but ANYWHERE you go, they're going to have to hook up the same number of leads... the more data points, the more effective the study. That said, my experience was quite different that Ian's. The office staff was quite courteous, Dr. Singh was helpful and actually took interest in the issues I was having. I had two sleep studies there, and had different techs both times, but both were courteous and worked quickly and efficiently. No complaints (and I can be difficult to please - check out my other reviews), i'd recommend Tri Valley Sleep Center. read more

What a great place!!! The rooms for the sleep study's are so welcoming and comfortable. I have to mention Joy, specifically. Sure as wonderful, very thoughtful and took extra care to make sure i was taken care of. read more

If you must go to a sleep center, I would highly recommend here. Most doctors offices run like the DMV. This place treats you as an individual, they are up front abd treat you as a person. read more

Summary: Do NOT trust this office: Doctor Singh, the nurse (cannot recall her name), and the scheduling staff. They are not a trust worthy group and are not worth your time or money. They may appear friendly but will use scare tactics to get you to do the sleep study (which is very expensive), then will try to continue to convince you for a second test and beyond. My story: I've always been a snorer and always wondered if I have sleep apnea. I finally did some searches on Yelp and found Tri Valley Sleep Center with positive ratings (albeit only a handful of reviews). I ended up doing a consultation and then staying one night for the sleep apnea test. The good news is that they confirmed I do NOT have sleep apnea. The bad news is that they don't follow-up, don't follow-through (staff said she will call me back to schedule a follow-up with doctor - never happened). The ugly is that they continued to try to convince me that I should take additional sleep apnea tests to test for other issues like epilepsy(?!). This place is dishonest and I would NOT recommend anyone to come here. Reviews of their staff: Front Office: from a customer service perspective, they fluctuate between "nice" to "I don't give a sh*t" to "I have no idea what's going on." They also do not know how to use their scheduling system or the webcam system (for a debrief with the nurse/doctor). Finally, don't trust them when they say they'll follow up with you to schedule any appointments - you need to be proactive and call them back. (At least this is my experience) Nurse: The nurse is generally friendly, but will use scare tactics to convince you that you need to take the sleep apnea test. During my debrief, the nurse notified me that I am actually a very healthy sleeper, but quickly followed up with additional questions to convince me to take another sleep apnea test. She started to become more and more pushy until I told her I'd prefer to talk to the doctor to get his opinion. Dr. Singh: Rude, unhelpful, and did not offer any real advice. Dr. Singh reconfirmed that I do not have sleep apnea and that I'm just a snorer. Since I spent quite a bit of money for the sleep apnea test and to see Dr. Singh (a "sleep doctor"), I was hoping he would at least be able to give me advice on how to minimize or prevent snoring. Instead, he said general things like, "There are products out there you can get to might help lower your snoring." (In my mind, I was thinking, "No sh*t, Sherlock! I can easily Google that myself without paying thousands on a sleep study and to talk to a sleep doctor!") I essentially had to ask follow-up questions to get Dr. Singh to be more specific. At the end, he finally recommended only one product "Theravent" without saying how effective it is, and offered no other advice. Theravent has only ok reviews on Amazon. So much for relying on an "expert." Sleep study facilitator: The lady who assists you DURING the sleep apnea test is the only person I had a thoroughly positive experience with. She was kind, responsive, and seemed to know what she was doing. Unless you want to be scared into taking multiple sleep apnea tests, and drop hundreds or thousands (depending on your health insurance), I recommend that you stay away. Learn from my horrible experience. read more

Being a sleep specialist myself, as well as a sleep apnea patient, I feel well qualified to give Dr. Singh and his staff a great review. His center for sleep feels very much like a hotel room rather than a sleep clinic. The bedroom was comfortable, the office and bathroom were clean and the surroundings were calming. Dr. Singh shows a deep interest in a complete diagnosis and is very thorough. read more

Dr. Singh has a solid background (you can see his resume on the website, and find other articles about his work throughout the web) and is highly competent in the sleep field. He genuinely wants to help you, and is willing to do what it takes to get you some good sleepy time. His operation, along with the sleep center, is very organized and modern - they now have a profile and appointment tracker all online for you where you can update your medical history and check your appointment times. They also do a thorough questionnaire every time you go in, and Dr. Singh reviews and updates your records thoroughly on every appointment. This is not an assembly line operation. In addition, the office staff is superb. They are always very responsive to requests and very friendly. Dr Singh is also very responsive and actually responded to me quickly on an urgent matter which I greatly appreciated. A+ for Dr. Singh and the entire sleep center organization. I love these guys! read more

After a horrific experience at Stanford Sleep Medicine, I came here and was pleasantly surprised. Their rooms are comfortable and both techs I had were very friendly. I was there overnight and most of the next day for a PSG and MSLT and had a very good experience overall. Of course trying to fall asleep with electrodes and an oxygen monitor on you isn't an ideal situation, but it's an inevitable part of a sleep study. Also, both techs asked if there was anything they could do to make it more comfortable (i.e. adjust the thermostat for me, get me another towel to wipe electrode glue off, etc.) Additionally, the center has several opportunities to provide feedback/concerns-- they provide you with a form as part of your registration packet and give you another one with your post-study questionnaire. Dr. Singh was attentive and spent a lot of time with me during my consultation and his office staff were very friendly. In other words, it's the complete opposite of Stanford- at TVSC, I found the staff to be punctual, helpful, and well-informed. read more

I am amazed at the number of people that give this place high marks. I went for months, and other than a very large bill to my insurance company, I received no help. In addition, I would not know if there is a Dr. Singh, as in all my time, I never met him. There are other places that can resolve your sleep apnea, but this is not one of them. Please refer to Kenneth T. review. read more

Hoaky operation. Went the first time and they had so many wires hooked up to me that I could not sleep. Went back for the second appointment and the tech was rude and when I asked about the mask options he indicated that if I didn't like them it is was my problem. After trying for 5 hours to get some sleep I finally told them that this didn't seem to be working. The tech came back a few minutes later with a form that said I was refusing treatment. I never heard back from anyone at the clinic. Pretty crummy operation. read more

Physician Dr. Singh evaluated and helped my husband with snoring/sleep apnea difficulties 5 years ago. That involved spending the night in the clinic hooked up to lots of wires which are recording your sleep pattern. The technician was knowledgeable and precise with set up and monitoring. What a difference that test made for my husband as he now faithfully uses a CPAP machine while sleeping. No more snoring, total quality rest (for both of us)! Once stabilized, an annual visit to Dr. Singh is scheduled to evaluate use and settings. For difficulties in between there is plenty of back up support from office staff and equipment vendor. read more

The staff here is wonderful! Best experience of my life. I am so glad I had this study done. It has changed my life as well as my families. The staff at Tri-Valley is so supportive and helpful. I thought sleeping over would be a little weird but they made me feel right at home. I recommend Tri Valley Sleep Center to everyone having any sleep issues! read more
