About Somnos

Everyone deserves a good night’s sleep

Sleep testing provided in a non-hospital environment for your comfort and convenience.Since 1990, Somnos Sleep Disorders Center has been providing comprehensive testing, diagnosis, and follow-up for a wide range of sleep disorders including narcolepsy, leg movement disorders, and parasomnias. Sleep apnea is the most common disorder we encounter and we even assist individuals suffering from shift work sleep disorders.

Good sleep plays an essential role in one's health and quality of life. Our overnight sleep testing will help you learn more about your sleep patterns and allow you to take an active role in your own care. Our medical team will conduct your sleep study, develop a diagnosis, and in consultation with your doctor, recommend appropriate treatment or therapy.

When your doctor refers you for a sleep study, the first step will be to schedule an appointment. Testing is always scheduled to match each person’s normal sleep time.

See For Patients for complete details about sleep studies.
