Meet your Certified Registered Nurse Anesthetists

Certified Registered Nurse Anesthetists (CRNA) are licensed professional nurses (RNs) who undergo extensive training and become nationally certified by exam in order to care for patients' anesthesia needs before, during and after surgery or the delivery of a baby.

Nurse anesthetists stay with their patients for the entire procedure, constantly monitoring every important body function and individually modifying the anesthetic to ensure maximum safety and comfort. CRNA's administer approximately 65 percent of the 26 million anesthetics given to patients in the United States each year.
