Our Offerings


Currently, 88 different known sleep disorders exist, with the most common such conditions including sleep apnea, narcolepsy, restless legs syndrome (RLS), periodic limb movement disorder (PLMD), and REM sleep behavior disorder (RBD). At the Cedar Valley Sleep Center, we conduct diagnostic sleep studies, or polysomnograms (PSG), to electronically monitor a person’s sleep and assess whether he or she is suffering from any of these conditions. Our testing process is simple: after a referral from your primary care doctor, our sleep specialists will schedule a time for you in the evening to undertake a sleep study at our diagnostic testing facility in Waterloo, Iowa. With a relaxing, home-like sleep area, many patients are able to fall asleep with relative ease and begin this noninvasive, pain-free procedure.

By gently affixing multiple sensors to your body to track your body’s vital signs during sleep and taping the study, our team is able to identify areas of sleep abnormalities, which aids in developing an individualized treatment plan. After the study, each patient then visits with his or her referring physician to discuss the test results and begin their treatment options. To find out more about our testing, click here.

Our Philosophy

At the Cedar Valley Sleep Center, we offer comprehensive, convenient, and affordable sleep studies. Our complete diagnostic studies test for many of the most-common sleep conditions and are conducted by experienced and knowledgeable specialists. This all occurs in our home-like sleeping environment and testing center, which doesn’t require you to check in at a hospital desk or walk through a large and complex building. And because we are an independent-testing facility, we’re more cost-effective than hospital-based testing, which can be more expensive for the same services. Through this model, the Cedar Valley Sleep Center provides its patients with an understanding of their sleep habits, all through a comfortable and affordable process.
