They offer 1 appointment time a week on Wednesday from 10am to 11am and call and harangue you for the $35 payment before they provide you with your in home sleep study. The equipment I was given wasn't working properly when the technician demonstrated how to use it. She played around with the connections, changed batteries and then sent me home with it. It was clear from the looks of the equipment it had had a hard life. I followed the instructions explicitly and had to reset 5x with no improvement. I slept with it attached hoping I was wrong and took the equipment back the next morning. I told the technician who gave me the equipment about the issues and she ignored me as she entered their office. I told the front desk attendant the same thing and she said "we'll see if there's any data to download and then call you". Of course there wasn't - it didn't work. They called two days later to ask me to come back during their one and only time to pick up equipment- Wednesday at 10am - and start all over. I told them I'm going to a different sleep specialist and to refund me the $35. She hung up. Inconvenient, Insulting, Improper. read more

Folks, I don't normally leave reviews, but in this case, I'm hoping to save others from the frustration of dealing with this business, specifically the location on Knightsbridge. The doctors are nice enough, but every other aspect of working with them is terrible. The dark-haired lady at the front desk is a nightmare of rudeness. I called to change my appointment to pick up my machine to an earlier time, which the gentleman I spoke to said was fine. When I arrived, the lady at the desk was nasty and complained that I was too early and that it was my fault I had to wait so long. She said her team member never told her about the schedule change. I stood there waiting for her to realize this was an internal communication failure, something she should have taken up with her colleague instead of berating me for it. I waited in vain. She never apologized, just continued on with her poor client service. Thankfully, another team member overheard and quickly moved to prepare my things. The same woman snapped at my husband when he came for his appointment. She yelled, saying he had the time wrong. No, he didn't. I heard him make the appointment. Ultimately, he drove all that way for nothing, as she refused to accommodate him or admit that once again, they had made a mistake. For over a month now, I've been attempting to get the prescription ordered by the doctor sent over to the provider who needs to fulfill it. I've called, and the other provider has called multiple times. No response, no action, no explanation. Here is a practice whose sole job is to help people get the medical care and support they need. Instead of doing that, they are literally stopping that from happening. There are so many great doctors and service providers out there. Do yourself a favor and move forward with one of those. Don't waste your time with these people or subject yourself to the rude lady who would rather yell at patients than do her job. read more

I had a sleep study scheduled for 8:30 PM. I was reminded several times by this group that if I don't cancel at least two days in advance, they could charge me $150. 2 days before, I confirmed that I would be there at my appointment on time. However, 90 minutes before my 8:30 PM sleep study they called me to cancel. The next morning they called to ask me to reschedule. I told them I would find a more professional group to work within the future and to please do not call me and ask me to come back. I also contacted my physician to suggest he no longer refers his patients to this group. read more

May 20, 2025 I had a sleep study appointment at the Grove City location for insomnia. The one closer to us couldn't get us in til much later. We had to drive an hour through terrible construction on I71 S. We had booked a hotel so my husband could be close by and I could sleep there in the morning if needed. We arrived a half hour early at Capitol Sleep at 8 pm. The reception area reminded me of a car repair shop waiting room. It looked grungy and dated. When I signed in, the receptionist behind a plexiglass cage told me my appointment had been "rescheduled". I showed the receptionist the letter I received stating the date and time. But that didn't phase her. She could NOT tell me to what date or why. She said we could hang around to see if someone didn't show up. All the patients showed up. We were turned away. I was devastated. When we got home I called them and after finally reaching the person who could tell me what happened, she stated that the technician's flight had been delayed. We had understood that there were 3 patients to one technician. Therefore, I should have been in one of those groups of three patients. I've never been treated so poorly in my life! They didn't leave voicemail on our landline as they had previously done. They left voice mail on the phone app on my tablet! I had left my tablet at home for safe keeping. I saw her message on the phone app on my tablet after I spoke to her. I dont understand why she didn't leave voicemail on both numbers. I tried to get my money back. I was directed to billing which I was told is a "3rd party billing company" based I'm pretty sure in India. He told me to call Capitol Sleep to get my money back. Capitol Sleep didn't know why he told me to call them. So far, I haven't heard about my refunds from Capitol Sleep. To date, I am still suffering from insomnia which is causing me anxiety, panic attacks, anxiousness. I managed to get on a "wait list", but that center doesn't take my insurance. I saw my Primary Care Physician today who recommended CBTI and EMDR. At the consult, my husband and I felt that the doctor at the Capitol Sleep Knightsbridge location was trying to put answers in my mouth. Luckily, Capitol Sleep had a questionaire online so I was able to change some of my answers. I think Capitol Sleep is only sleep apnea minded and doesn't offer diagnosis of other possible causes for insomnia so I think they weren't a good fit for me anyway. I would have selected zero stars, but my review wouldn't post. May 2025. read more

I have been seeing Dr. Walter since 2017. He is very understanding and gets your apnea under control. I use my AirSense 10 every night. I sleep great and feel great when I get up and through the day. read more

Thorough, helpful, positive staff and doctors. Facility is dated and parking lot is too dark when exiting a sleep study.

Friendly courteous staff. They answered all of my questions and made me feel comfortable with the upcoming sleep study. Easy to find facility and plenty of parking. read more

I really like all the staff, and dr. Walters is wonderful. I actually drive an hour one way just to go here, when there are more places closer to my home. read more

This is a great faculty. I was recommended these doctors by a co-worker whom I trust. I met with Dr Mahar via Telehealth and she was wonderful. She set me up with an in home sleep study which showed what I had always been told, my snoring and breathing was terrible at night. Due to the COVID pandemic she set me up with the Dreamstation auto machine, that has worked perfect .i have had several appt with her, and she has helped so much with my mask troubles, and even finally got me in the lab for a sleep study. The ladies at the Grove City location are wonderful .i am so glad I found Capital City Sleep medicine. My husband is now back in our bedroom every night, and I am feeling better day by day. My blood pressure is even under control. Thank you read more

I know how much I need this machine to sleep and I've had almost flawless experience witk Dr Marar. my only concern was two years ago she wasn't seeing patients in person. that I didn't care for. a telephone call is not a Dr visit. but I was, or my insurance was billed as such. that's wrong. not to mention I still had to go to the office with my machine. her office staff still met and talked to patients. this seems so wrong on so many levels read more

Very easy to work with and do a great job at making sure I have the supplies I need, when I need them. Never wait too long and the process to check in and out is very easy. read more

bad communication. pre-authorization is very slow. would put a 0 star if i could. if you need something serious treated please don't go here. read more

I would avoid this practice. I came in as a new patient as an existing sleep apnea/CPAP patient. (My previous sleep clinic closed.) First off, the staff is friendly and kind but as I was sitting in the waiting room for my initial appointment and one of the workers behind the closed glass window started complaining and not saying kind things about the patient she just hung up the phone with to her co-worker. The others sitting in the waiting room and myself could overhear this. Extremely unprofessional. I should have walked out then. I was seen by Dr. Warner who is pleasant and took the time to listen to my story, my health history and the current plan of treatment that I have been on. He ordered a sleep study (even though I am reluctant to do another one) in order to fine tune my settings on my CPAP machine. When I told him I was not thrilled with doing a sleep study when my current plan of treatment is because I am sleeping well and according to my stats on my machine I have very few "events". He then said to me, "So sorry,CHARLIE" as if I was pouting about it. Looking back on it I felt a bit embarrassed. I then told him I would try the sleep study if that is really what he thinks I need. I had told him that I am in need of a new CPAP supply prescription (which drove me to make my new appointment with a new practice) in order to continue with my current plan on my machine until the sleep study is done. I walked out to schedule my sleep study with a lovely staff person. They had already called my insurance to see what I would need to pay out of pocket. It was nicely given to me but was incorrect. ( I have met my deductible at 100 percent) I had mentioned this. I did not want to pay the large amount stated by them until I could call my insurance to see what was going on. Therefore I didn't want to schedule my sleep study until this was worked out. I was then brought to the supply room in order for me to "purchase" the supplies I need for my machine (which I am out of). I was told my prescription was not yet uploaded by Dr. Warner. I saw that the prices of their equipment were much higher than where I was previously ordering them from(Ohio Health). I told her I would like to walk out with my prescription so I could continue with the vendor that I prefer. She said that she would ask Dr. Warner to upload it into my patient portal and it would be there soon. Fast forward-went home, called insurance and then started the process of trying to get back in touch with their office. Their immediate answering prompt tells you that they are experiencing a "high volume of calls" at this time. I followed prompts to the appropriate people I needed to talk to concerning my prescription and my "deductible" that they are still insisting I will need to pay. I left over 4-6 messages (I lost track) over a 3 week period with not one phone call from anyone in their office. Their office pushes you to communicate through the patient portal but in that 3 week period my account was deactivated ( even though I had been in it before my appointment to fill out all of my electronic paperwork). By week 4, I talked to IT who then reactivated my account and I then sent an email to Dr. Warner with my complaints of no one calling me back, asking for my prescription AND asking for someone to call me concerning the financials/Insurance. I did hear back from him in a timely manner which he jumped to the conclusion that I am not willing to do the sleep study and therefore he is "not comfortable" writing me a prescription for my current supplies. He wrote "he was sorry for my frustration". NOT "I am sorry that no one has gotten back to you and I will make sure someone calls you as soon as possible to work out this insurance confusion." In my first email to him I told him I was going to contact my ENT that referred me to him and that I was going to fill out the patient survey that was texted to me. Dr. Warner's response was that he called my ENT and thoroughly talked about my case already with him and that it is his professional opinion that I need a sleep study due to my wait and my cancer that I am battling. I feel so put on the defensive and frustrated that I cannot get a hold of my supplies that are desperately needed. Moving forward I will not be choosing Capital Sleep Medicine to be on my team-helping me on my journey. PLEASE consider my experience when choosing whether to go to Capitol Sleep Medicine. read more

I have been to 2 other sleep clinics in town and this is the first time I saw the doctor. My problems were fixed and I feel great. They get you in quick and are CHEAPER than other places. Good follow up too! Happy lady!! read more

The only friendly people there are the receptionist s. Had to do 2 sleep studies because the first one couldn't be read. Met another patient in lobby, and she was told the same thing. That shouldn't be happening. read more

I have been a patient of Dr Marar for over 15 years and feel the recent post by Thomas H, reflects inaccurately on this practice. Thomas raises issues that are a patient's responsibility and their referring or family physician. Sleep Apnea is sleep apnea, period. Avoiding the need for a CPAP by a life of healthy diet and excersice are long overdue when folks end up at a sleep clinic. Why is it surprising that most patients referred are predisposed for an array of reasons? Its like blaming the oral surgeon for doing a root canal instead of counseling the patient on good oral hygiene. Thats not there concern, the infected nerve is their issue, just like the sudden cessation of breathing by a sleep apnea patient, is Dr Marar's issue. My sleep studies and subsequent treatments have been highly professional. The impact of using a CPAP whenever I sleep for 15 years has without question saved my life. (ps even some thin and healthy people have Sleep Apnea) Mike Z read more

First Dr. Walter was 20 minutes late getting me back into the room. He was very one sided and did not listen to what I had to say. It was pretty much oh you're overweight you snore and you have headaches, close closed. I had headaches because I grind my teeth at night (Dr. Lordo told me). I know this because I wore a mouth guard for 7 days and I have not had a headache in 2 months. I don't like being talked down to and ignored. He gets 1/5 stars. The sleep study was not that bad, very comfy bed, flat screen and cable. The tech was great, very funny and comforting. He was there in the middle of the night to talk when I had questions. Oh you cannot bring in your own blankets and pillows because of bed bugs, so please ignore the previous lady. Just received a bill for more than United Healthcare says I owe and, says Im over 30 days late. I have a receipt and a bank statement saying I made a payment almost a month ago. I called last Monday, Tuesday and today and no call back. This place is a joke. I went to another sleep apnea specialist in Dublin who was fantastic and look forward to seeing him. So please please look around before you spend your money on this place. read more

If you are serious about getting the help you need for a serious sleep problem, avoid this facility. Real sleep issues like sleep apnea and insomnia should be treated by professional doctors, not greedy salespeople like Dr. Marar and the staff at Capitol Sleep Medicine. From the moment you walk into their waiting room, you see patients that are mostly overweight, carrying their CPAP machines with them to their appointments. After your initial consultation, you will be scheduled for a 2 night sleep study where you are monitored overnight and your sleep patterns are documented. The first night is just a regular night and then the second night is with a CPAP machine. You are told after the first night that you probably have sleep apnea and that you would benefit from the use of a CPAP machine and that the second night you will be fitted for one. They use scare tactics telling you that elevated blood pressure, heart attacks or strokes are likely and that sleep apnea will eventually cause your death. While there are serious medical problems associated with sleep apnea, Capitol Sleep Medicine does not address the root cause of sleep apnea itself. Simply losing weight causes great improvement in both high blood pressure and sleep apnea symptoms, but weight loss or an exercise program is never offered as treatment by Dr. Marar or anyone else at Capitol Sleep Medicine. Their only approach is getting you to use a CPAP machine. They are like a factory sales floor for CPAP machines. They take advantage of insurance companies and individuals by pushing these horrible machines. They don't even explain the potential side effects like hearing loss and the respiratory problems associated with CPAP use. The pressure that builds up inside the ears have caused hearing loss in many patients. You can reference my comments on Google and see firsthand the high number of people that have had health problems from using CPAP machines. One final note. If you question the almighty Dr. Marar about alternatives to using a CPAP machine, you will be dismissed and spoken to like a child. Her condescending attitude is unprofessional for a medical official. Her attitude is one of "How dare you as a common, uneducated person contradict my authority and education." She is a salesperson in a lab coat. I believe her only purpose is to sell as many CPAP machines as possible to boost her bottom line and fill her bank account. I hope my review helps others in avoiding this corrupt facility. Thank you for taking the time to read this, I know its long, but if it saves one person from experiencing the horrible service that I received, its worth my time and yours. read more

I did a combined overnight (polysomnogram) and daytime (multiple sleep latency or MSLT) test. I had to report around 8:30pm; the center is on the south side of Old Stringtown Road and the sign is kind of subtle; the map is pretty good though, and I get lost easily. The techs let me bring in whatever I wanted, and just like it said in the guidelines they had a fridge for me to put cold stuff in. They hooked me up pretty fast - maybe 20, 25 minutes - and let me read in bed with a lamp nearby till I was ready to fall asleep. It was only a little noisy, but when I go back for my titration appointment I'll wear my earplugs. Here's my advice: - Bring your own everything, including towels. Yes, I know they said they have shampoo and stuff. Just bring your own. - Also bring pillows and blankets as though you knew for sure there wouldn't be any. Special hugs to IKEA's relatively expensive pillows, BTW. - Bring a robe. During the day you are sharing the hallways with the staff, the day patients there for appointments, etc. - Wear a sleep mask, if they'll let you, for the MSLT. The window coverings are only about 99% effective. - If you don't like Bob Evans food and water, bring your own food and water. If you do like Bob Evans food but suspect that it won't be enough, bring your own. (If I do this again I will be bringing caffeine free beverages like root beer.) Really just bring your own, you'll be happier. - Have your own water bottle; it's a hike to the water cooler. - Also have flip-flops or shower shoes; it's a (much shorter) hike to the bathroom. - Use the bathroom that isn't closest to the reception area. I know it has a shower in it; that's still the one they direct all the daytime visitors to. - They ask questions no one can realistically expect you to know the answer to ("Did you sleep?" "Did you dream?" "How many minutes would you say you were awake?") Guessing is apparently fine. - Don't be a hero, just take the sleep aid you were given. When they wake you up at 3:30am because your pulse oximeter fell off your finger, it is probably going to be a bit harder to fall asleep than it would have been at home, and the day is going to be very very long. - Bring chapstick. The reason you want the chapstick is because they stick a thing in your nose and mouth that keeps them open all night long. (I will be putting the chapstick by the bed, along with the earplugs and the sleep aid bottle, for my titration appointment.) - If you didn't get woken up to switch to the CPAP halfway through the night, they don't tell you squat about how you're doing. Don't bother asking. - Eat sensibly the day before. The popcorn and lemonade in lieu of dinner on Sunday? Bad decision. - Practice sleeping on your back. They're going to really insist on that (in the end they let me switch, but only because I did a good three hours on my back first.) I also recommend searching MetaFilter for "sleep study." I asked a question about it before I went in, and got a lot of helpful answers. read more

The staff here are very rude and unhelpful, when you try to ask them questions just give you rude or snotty remarks and don't actually help you. Dr Marar, and the respiratory therapist were the most unhelpful. If they would just take a few minutes to listen, and try to come up with a solution instead of interrupting you or just telling you that nothing can be done. read more

Dr Murar is a nice person and appears to be a competent physician. With that being said, I was very dissatisfied with this establishment. Generally, the wait time was 20 minutes even though the office asks you to arrive early. There was typically a different employee in each position during each visit, which speaks volumes and they were often not knowledgable concerning insurance, the supplies or my condition. I have since moved on to another facility and was advised the pressure on my cpap should NOT have been adjusted based upon my last sleep study. Additionally, in order for my new physician to acquire my medical records, I had to fax the request SEVEN times. The only reason I give two stars is that Dr Murar is nice. Trust your health, and life, to someone else. read more

Well, I have to give 5 stars. I didn't see the Dr, but they called me back and took care of everything. I will say their phone system cut out, but don't worry. They call you back real nice. read more

I had my sleep study at the Old Stringtown Rd., Grove City, OH location. My technician was Reggie(If my memory is correct). He has had 14 years experience with them. He was so polite and explained everything. I felt very safe and comfortable with him. If I need another study in the future, I would request him....... Dr. Walter is very direct. I did not have an issue with his consultation. He is doing his job. Told me I needed to lose weight and quit smoking. I hear that from any doctor I go to - and I told him he had to tell me that as he was doing his job as a physician. What he said was true! I had my first sleep study in New York 7 years ago and needed a new sleep physician since moving to Ohio. Very pleased....... read more

This place has been very helpful in solving my sleep apnea problem. My blood pressure has gone down since I was prescribed my machine. Just got replacement parts and Amy was very efficient. In and out! read more

Absolutely the epitome of bad service. They made me come in and waste half of a work day just to schedule a sleep study and 2 other obviously unnecessary appointments. To top it all off they had the audacity to schedule an appointment on a date we did not agree on and then charge me $150 for the cancelation. If you can go anywhere else. This medical team does not deserve your time and much less, your money. read more
