High Quality Care in a

Convenient Environment

We founded Physicians Premier ER in Corpus Christi as a freestanding emergency room where patients could receive immediate care that was both high-quality and convenient. Time is crucial when it comes to critical health issues, but at common urgent care clinics, patients can become lost in the shuffle, forced to wait in long lines and receive lackluster care. Here, our team makes every minute count.

Upon entering our facility, you’ll quickly find that delays are a thing of the past. Patients are seen and assessed immediately upon walking in, and you’ll be sure to enjoy our calm, comfortable environment as we do our work. Our skilled physicians and nurses will make sure you receive the help you need as quickly as possible, and our advanced technology (including EKGs, CT scans, digital X-rays, ultrasounds, and more) will help to make the process that much smoother, saving you valuable time. You’ll find that you truly are in the best of both worlds – a skilled and upscale environment that avoids the common pitfalls and inconveniences of hospital-based ERs.

With a wide array of services at our disposal, our professionals are able to treat both adults and children for virtually any emergency issue you could come up with. From the flu to broken bones to burns, we have the experience and skills needed to understand and diagnose your symptoms properly. Plus, if our physicians determine that you or your family member requires the services of a hospital, we can immediately arrange a transfer and coordinate with surgeons to ensure you get the treatment you need. We want to provide you and your family with the excellent and attentive emergency care.
