The more he learned about sleep apnea, the more he became committed to helping others receive treatment for this life-limiting disease. He has committed to learning all he can about sleep apnea and dental sleep medicine to provide the best treatments with the best equipment for his patients. Dr. Cogswell is a member of the Minnesota Sleep Society, a Diplomate with both the American Board of Dental Sleep Medicine (ABDSM) and the American Sleep and Breathing Academy (ASBA), and a Fellow with the International Academy of Sleep (IAOS).
