How Will the Sleep Center in Los Alamitos Help You? 

The team at the sleep center in Los Alamitos helps patients throughout Orange County with: 

Sleep Studies: There are two primary kinds of sleep studies: in-center and in-home. In many cases, an in-center sleep study will be the best option to diagnose a sleep disorder. Our quiet, relaxing facilities are like a hotel—you’ll have everything you need to sleep normally. Your private, comfortable room has a shower, you’ll find a restroom nearby, and sleep technologists are always available if you need any assistance. 

If you’ve been recommended an in-home test, our team will walk you through the process step-by-step to ensure it is administered properly, and you get the results you need.

CPAP Devices, Supplies & Training: CPAP devices are a common treatment for sleep disorders. If you’ve recently started to use a CPAP or have a new device, our team will help you understand how it works.  And ask us about our resupply program, so your replacement supplies will arrive exactly when you need them! 

Understanding Insurance: If you’re unsure of how your insurance coverage works when it comes to your diagnosis and treatment, our team is here to help answer any questions you might have.  ASMS is in-network with dozens of insurers to make treatment affordable.
