Our Story

Greg Stirrett, the Founder and CEO of Rebel Sleep Institute, brings years of experience in leading high-achieving teams across small, medium, and global sleep and respiratory organizations. Over time, Greg recognized a significant gap in the industry. While there were numerous "CPAP" companies, very few, if any, approached the management of fatigue and exhaustion from a truly multidisciplinary perspective. This approach not only encompasses CPAP therapy but also integrates a wide range of evidence-based fatigue solutions into the treatment process.

While sleep apnea is a prominent contributor to exhaustion, there are often other underlying factors that go unnoticed. Rebel is deeply committed to assisting individuals in removing the barriers that frequently hinder them from being at their best, both in their personal lives and at work.
