At Tucson ER & Hospital, we opened our doors to do one thing – put the care back into health care.
Tucson ER & Hospital is a part of Nutex Health (NASDAQ: NUTX), bringing communities accessible, concierge-level care they can trust.
We are physician-owned and pride ourselves in offering state-of-the-art testing and diagnostics while providing value-based quality care. Our mission to provide immediate and unparalleled care makes us an ideal choice for emergency, imaging, clinical, pediatric, occupational, and outpatient care.
We hope you never need our services but if you do, we are always here. That’s a promise you can count on.
“We hope you never need our services, but if you do, we are here when you need us. That’s a promise you can count on.”


We’re putting the care back into health care. Come feel the difference.
With on-site radiology and laboratory 24/7, we can provide our patients with rapid test results. We understand how nerve-wracking waiting for results can be, so we have minimized the wait time. This means that instead of our patients waiting to receive results, they can work with our physicians and focus on treatment plans that will help them get better.
We offer elevated medical capabilities such as pediatric emergency treatment rooms, advanced cardiac life support, and EMS ambulatory access. Our facility offers clean and spacious waiting rooms, an elegant atmosphere, and a friendly staff. We understand the importance of every detail, no matter how small, and know that it can greatly affect our patients’ experience.
