Dallas Regional Medical Center opened in 1964 as Mesquite Memorial Hospital. The hospital had 27 beds, five bassinets, one operating room, one delivery room, an Emergency Room and seven physicians on staff. The hospital was expanded in 1975, purchased by Charter Medical Corporation in 1976 and renamed Charter Suburban Hospital. The campus continued to grow through the 1980’s with the purchase of a three-story medical office building. In 1990, the hospital underwent another ownership and name change when Paracelsus Healthcare Corporation, later known as Clarent Hospital Corporation, renamed the hospital Medical Center of Mesquite. Today, Dallas Regional Medical Center is a member of Prime Healthcare Services, a nationally renowned healthcare system.

A full-service Heart Center was established in 1991. The Heart Center included a cardiac cath lab, open-heart surgery, cardiac rehabilitation, a centralized outpatient diagnostic and surgery area and a new Emergency Department. Since this time, a second cardiac cath lab has opened and nuclear medicine/special procedures have continued to grow.

The hospital campus expanded in 1994 with the acquisition of commercial property located to the south of the medical office building. This property today contains both hospital office space and physician office practices. In 1996, a three-story patient tower was constructed on the north end of the hospital. This tower currently houses a 14-bed Surgical Intensive Care Unit on the first floor, a 10-bed Orthopedic Unit and Total Joint Center on the second floor, and a new Cardiac Care Unit on the third floor with 26 private suites that opened in May 2009. In 1998, a parking lot behind the medical office building was constructed, allowing for an additional 100 parking spaces. One acre of land north of the Emergency Department was purchased in 2000.

In 2005, we expanded the busy Emergency Department into the current 23-bed unit, with eight Fast Track bays. The hospital name was changed to Dallas Regional Medical Center in 2007.

Today, Dallas Regional Medical Center is licensed for 202 beds and is accredited by The Joint Commission. Throughout 2008 and 2009, the hospital has undergone extensive renovation and construction projects that have resulted in a modern and progressive hospital to serve people in Mesquite and the surrounding communities.
