Dryden-Edwards Psychiatric Services (formerly Glasser Medical Psychiatric Services) is one of the oldest operating psychiatric practices in Montgomery County. Over the last 30 years we have provided a wide range of psychiatric services to adults and children in the Washington, D.C. metro area.  We have five physicians available to assess patients quickly and eight clinicians on staff to provide psychotherapy services to children as well as adults.  Saturday and evening hours are also available.
