MedStar Health is a $2.9 billion not-for-profit healthcare organization and a community-based network of seven hospitals and numerous integrated businesses in the Baltimore-Washington region. The hospitals, which include both teaching and community facilities, are Franklin Square Hospital Center, Good Samaritan Hospital, Harbor Hospital, and Union Memorial Hospital in Baltimore, Maryland, and Georgetown University Hospital, National Rehabilitation Hospital, and Washington Hospital Center in the District of Columbia. MedStar Health is based in Columbia, Maryland and as the area's largest health system, it is one of its largest employers, with more than 23,000 employees and 4,600 affiliated physicians, all of whom support MedStar's patient-first philosophy that combines care, compassion and clinical excellence with an emphasis on customer service. We prove this everyday with 145,000 inpatient admissions and more than one million outpatient visits each year.
MedStar employees proudly serve a half-million patients annually, and our employee satisfaction exceeds the national average for healthcare companies by five percent, which translates into a workforce dedicated to providing the highest quality care to the communities we serve. We contribute approximately $85 million in payroll tax to the District of Columbia, Maryland and Virginia each year, and believe in re-investing in our employees through professional development programs, such as the Executive Development Institute and the John L. Green Generation of Leadership Scholarship Program. Additionally, MedStar Health provides more than $178 million in charity care and community benefit on an annual basis.
MedStar Health's areas of clinical excellence include cardiology, cardiac surgery, oncology services, rehabilitation, neurosciences, orthopedic surgery, sports health, women's services, and emergency and trauma services.
