This was my first visit. I had unsatisfactory prior CPAP experience and was looking for an actual sleep specialist to work with to help me. My initial visit went great the Doctor took his time with me. Clearly explained options and made me feel very comfortable that together we will find a way for me to get a good night's sleep. Looking forward to working with him and his team.

Dr. Mahmood Dweik and the CLS Health Sleep Center team delivered care that was both clinically precise and deeply respectful. From intake to follow-up, every step honored my time, my questions, and my dignity. Dr. Dweik listened intently, explained the sleep study process with clarity, and made sure I understood the next steps without rushing or jargon. The staff communicated with warmth and professionalism—even the automated messages felt thoughtfully designed. I felt seen not just as a patient, but as a person navigating real-life exhaustion. If you’re looking for sleep medicine that blends science with compassion, this is the place. I’d recommend Dr. Dweik and CLS Health to anyone seeking answers and restoration.

- 4 out of 5 starsReviewed on 5/20/2022
I thought the doctor and staff were excellent. I gave them a four-star because they are not up to date when it comes to prescriptions.. I had to take a paper prescription, drop it off after sitting in line for a while and go back and pick it up after sitting in line again. It was basically the time factor that I had to use by making two trips and sitting in long lines.

I have an older Dream Machine CPAP that I use for travel and the data I need off of it has to be read off the SD card. I went to see Rebecca Rodriguez at CLS Webster for this work. Ms. Rodriguez is ALWAYS extremely helpful and accommodating as she produces the data I need. The folks in this office are always nice and helpful. I will be back….thank you again Rebecca!
