Dr. Austyn P. Belle Isle, DNAP, CRNA, APRN
Owner & Lead Aesthetics Injector
Building on a critical care background caring for trauma, surgical, and burn patients, I pursued advanced practice training to become a Certified Registered Nurse Anesthetist at the University of Alabama, Birmingham (UAB).
I returned to Columbia in 2012 as CRNA. I completed my terminal degree as a Doctor of Nurse Anesthesia Practice in 2018. I continue to deliver anesthesia in the mid-Missouri area and I love making hard days easier through my heart and hands.
I received my Aesthetics Injector Certification via Aura Aesthetics Academy in 2020. I am also a member of the American MedSpa Association, American Association of Nurse Anesthesiology, Missouri Association of Nurse Anesthetists, and the Sinclair School of Nursing alumni board.
​
I enjoy spending my free time with my family and friends, ideally outdoors --biking the trails, hiking, travel, reading, art, and live music.
