South Texas Health System first opened its doors in 1919 to provide care to the people of the Rio Grande Valley. STHS McAllen's full-service acute care facility opened in December 1985 after spending more than 50 years in downtown McAllen as McAllen Municipal Hospital, McAllen General Hospital and McAllen Methodist Hospital. STHS McAllen was the first in McAllen and neighboring cities to offer services such as open-heart surgery, one-day cardiac catheterization and magnetic resonance imaging. Today, it's become a large tertiary hospital for specialized treatment with a Level I Trauma Center - making STHS McAllen an invaluable healthcare asset in South Texas. We are also a Comprehensive Stroke Center.
