About US

The mission of the Academy of Sleep and Wellness is to cultivate knowledge and facilitate education in public, patient, professional and corporate communities on the vital role sleep plays in promoting and maintaining health and quality of life.

The ACADEMY OF SLEEP AND WELLNESS was established in 2017 as an independent educational body arising from the very successful education arm of Delaware Sleep Disorder Centers. With this separation, the ACADEMY OF SLEEP AND WELLNESS brought with it technologists and educators with decades of experience in their respective fields, including the holder of the first professional Polysomnographer License ever issued in the state of Delaware.

The ACADEMY OF SLEEP AND WELLNESS provides education for many different audiences including public, patients, corporations and occupational health programs as well as current and potential health professionals. Education is available in multiple formats ranging from live in-person presentations to self-paced online programs.
