CSCC has exceptional communication-lots of calls, texts, and emails. Their customer service has been very nice, professional, and helpful. Working with them for my son's sleep testing has been a good experience.

My last two appointments had been canceled and was told I could not be scheduled before January. I called the center and the agent, Liam D’Silva, was very helpful in scheduling me for tomorrow!

The guy who was there was great very professional!!! The problem I have when I did my telephone appointment. I told them how I take the mask off in my sleep. And how I snore with the mask on. They said they had different things to try to combat this. But when I went in there, it was like I was on the beginner program where everyone goes in therreTheir first time and they try the bypap over the nose over the mouth over both. This was frustrating and upsetting. I had talked to them about mouthpieces about remedy for my central apnea and about airlift for my obstructive apnea I had explained that I don't keep the masks on lots of times when I first put it on I have panic attacks and then I can't use it that night all night long What they gave me the bipap was really pushing a lot of air if I were somebody who didn't have panic attacks, it would probably work. Great. And if I didn't tear off masks in my sleep, I needed to try the other solutions. Mouthpieces ect... but please don't get me wrong. They seem like a really great place to go for sleep apnea. To guy who was assigned to me was wonderful. He was patient because I had panic attacks. I could not keep that bypap on my face over my mouth or over my nose or over both. I had waited and wanted to be able to do it if they tried that But something over my face is not a good solution for me Mouthpieces, or something else? It would be good. I think or I hope I don't know if it's possible to send me one that I can try or if it has to be there under their care. It's a little hard for me because I'm an hour away. I'm 64 years old. I don't like to drive at night as a matter of fact as a rule. I don't do it, but in this case, I have to in order to be there at 9 p m. I'm hoping I still have a telephone appointment. Or are they going to drop me? Because I could not wear the masks. If someone could please call me and let me know if I still have a telephone appointment or where do we go from here.

The phone message at the beginning of my call was quick and clear with instructions. The employee, Debrah was quick and clear. I do wish that I could get some communication with your business, what is the big picture. What steps/appointments are expected. I am a "new patient" and I don't understand what timing and routes of appointments are expected. When can I expect that I have fulfilled all of my entry into care. Also, when should I make appointments with my ENT doctor who is covering part of this care? Why do I make appointments with a doctor?

Mumtaz was extremely helpful and accommodating in rescheduling my appointment. She was understanding of my situation, patient, and took the time to answer all my questions thoroughly. I truly appreciate her kindness, professionalism, and willingness to help. I have consistently had positive experiences with the staff at CSCC, and I am especially grateful to Dr. Tomkinson for being so caring, supportive, and attentive to my needs. The compassion and dedication shown by the entire team have made my experience a very positive one. I highly recommend CSCC for their excellent care and outstanding patient service.

Mumtaz Begum from the Scheduling Department was kind and patient. I called in the day before but the representative brushed me off and didn't seem to want to help me with rescheduling. Mumtaz Begum not only was able to accommodate my needs but she also took the time to ask questions on why I needed to reschedule. I appreciate this type of customer service. Thank you Mumtaz.

Kevin is on the ball and perfect each time I interact with him on the phone. Too often telephone transactions are difficult when operators are not efficient nor well trained. CSCC and Kevin have made those interactions trouble-free. Thank you.

Comprehensive Sleep Center is absolutely fantastic. I was heard, my problems were listened to, and taken care of. They have always been so lovely on the phone. When I called to make my initial appointment, Clement J. made my consultation, my sleep study, and and follow up all right there. Everyone else I've talked to such as, Dominic R., Devanathan A., Preethi D., Mark S., Vigneswaran S., and all the doctors have been wonderful.
