The Northwestern Medicine Outpatient Center is located on the Huntley Hospital campus, and expands access to advanced cancer, cardiovascular and specialty care throughout McHenry County and the surrounding region. Built by Walsh Construction, the approximately 80,000-square-foot medical office building expands existing services while bringing several new specialties to the Huntley campus. The Outpatient Center expands oncology and infusion services, cardiac diagnostics, general surgery and urology, while adding gastroenterology, pulmonary medicine, palliative care and radiation oncology. The building also houses clinics for the Bluhm Cardiovascular Institute, Northwestern Medicine Regional Medical Group and the Canning Thoracic Institute.
