Robert Koenigsberg

In 1999, I began working with Dr. William Dement to create a high quality less expensive and more convenient resource for the millions of Americans who suffer from sleep apnea. Dr. Dement dedicated his life to advancing sleep medicine, and we shared the belief that the majority of both patients and primary care physicians are woefully uninformed about the ramifications of this serious medical condition. Dr. Dement made exhaustive efforts to educate the masses about the importance of a good night’s sleep and how we can identify and treat sleep disorders to live more productive and happier lives. SleepQuest is an extension of these efforts.

At SleepQuest, we aim to increase your knowledge about sleep apnea and give you access to diagnosis and treatment options that work for you. Above all, we are dedicated to helping you achieve the energy and vitality of life you deserve.

Robert is SleepQuest’s founder and CEO. He has spent 30 years in the healthcare industry and had the vision to create SleepQuest’s care management program in 1994 for patients with obstructive sleep apnea. Robert is recognized as an industry expert. He is a member of the American Sleep Apnea Association, American Academy of Sleep Medicine and the National Sleep Foundation.
