We re the largest private sleep diagnostics provider and the largest ambulatory EEG provider in the nation. Our hospital-based, physician-based and freestanding care sites have been helping American s sleep better since 1999. In 2013, we merged with Watermark Medical, the nation s leading provider of Home Sleep Testing (HST). Their ARES device pioneered cloud-based HST for obstructive sleep apnea by allowing primary care physicians to become the point of care for diagnostic testing. By developing innovative solutions for sleep disorders and raising awareness about the benefits of healthy sleep, we can help solve America s sleep problem.
