When you or a loved one has a medical emergency, nothing eases your mind like knowing quick and reliable care is nearby. The Emergency Department at St. Mary's Medical Center is open 24 hours a day, 7 days a week, providing quality care when you need it most.
What's more, our nurses and physicians are committed to triaging and seeing the patient in the first 30 minutes. Accidents and injuries are painful enough without waiting for hours in an emergency room. All patients are assessed upon arrival, and the most serious cases are given priority. After being seen by a physician, the total length of your visit may vary depending on what tests are needed, what the diagnosis is and what treatment is required.
When you need emergency care, come to St. Mary's Medical Center--and get in, get better, and get going
“Is it an Emergency?”
Sometimes it can be confusing to know when you should head to the Emergency Room. Tin Do, MD, an emergency physician, and the other staff of St. Mary’s ER tell patients who call: “If you believe it to be an emergency and don’t think it can wait to see your doctor, you should come in. You know your body best and only you know when your body feels strange.”

Tin Do, MD - ER Medical Director
According to the American College of Emergency Physicians, there are specific health conditions that are considered life threatening and others that require seeking immediate medical attention.
