Be aware that even though the name says "Urgent Care" they will charge you emergency room prices because they have emergency room technicians. No equipment to handle emergencies, but technicians.
Went there with my son and was told I needed to take him to Dell Children's after they took his temp and weighed him. Still charged me for an emergency room visit, and then sent me to a real emergency room so I could pay again.
I find this very dishonest. Can get the same "emergency" service at the clinic in the HEB next door for a LOT less.
