Southlake's approximately 31,000 residents are served by a community known for Southlake Town Square, Bicentennial Park, and Gateway Church. What Southlake doesn't have is a 24/7 freestanding emergency room with a full in-house laboratory.

That's why so many Southlake residents rely on ER Of Fort Worth at 4561 Heritage Trace Parkway — just 13 miles from Southlake via Hwy 114 & US-377. We are open 24 hours a day, 7 days a week, 365 days a year.
