David Hutchinson

David Hutchinson has been with the Center for Sleep & Wake Disorders in varying capacities since 1996. Since becoming a nurse in 2007, David has assisted our practitioners with initial patient intake and evaluation, and has served as a staff nurse on cardiac critical care units at Washington Hospital Center and Holy Cross Hospital. David has enjoyed seeing patient care at the Center for Sleep & Wake Disorders from many different perspectives, and has enjoyed seeing our patient care model develop and grow over the years. As the medical informatics administrator, David is very involved in our continuing, and, he believes, successful efforts to enhance the quality of our clinical care by integrating new information technologies into our patient care processes. In his spare time, David enjoys reading, spending time with friends, and volunteering for the DC Rape Crisis Center.
