Care Team

At North Memorial Hospital, patients receive the highest quality of emergency care from our trained and multi-disciplinary team of professionals. This team – including emergency physicians, nurse practitioners, physician assistants, air care and ambulance providers, and paramedics, to name a few – are all ready to respond to the immediate health care crises of area residents.  

All of our emergency physicians are residency trained and are either board certified or eligible with the American Board of Emergency Medicine. They serve not only the Robbinsdale campus but also Maple Grove Hospital’s Emergency Department. This partnership ensures we are able to streamline the patient’s experience in our system of care.

Our Ambulance and Air Care team includes critical care flight nurses experienced in emergency medicine, intensive care and pediatrics; flight paramedics with years of experience in busy ground ambulance systems and an accredited Communications Center recognized for the highest level of standards in emergency dispatch.
