Dr Crean has spent over 25 years in the dental and medical community providing care to patients. Starting out as a Registered Dental Hygienist with a Masters degree in Public health then onto dental school has allowed her to view the field from many different perspectives. She spent 10 years working with craniofacial pain , TMD , and sleep patients as a partner at the Craniofacial Pain and Sleep Center of Arizona. While working with this special group of patients it had become apparent to her that the correlation between oro-facial anatomy and sleep breathing disorders was an area that needed more discovery. This led her to pursue a PHD in neurobiology with an emphasis in sleep medicine. Combining dentistry and sleep medicine gave way to the birth of Sleep Alternatives, LLC.
