Paul Tull, CRNA

-JL McClellan CAVHS

Paul W. Tull graduated from nursing school in 1990 and worked as an RN and unit manager for 12 years before heading off to anesthesia school. During his pre-anesthesia days, the Emergency Department was his home for several years, along with a stint in CCU before getting interested in management. He earned a MA in Health Services Management while working as a shift supervisor on a Med-Surg floor. Soon, he settled into a unit manager job of an Out Patient Services Department.

When he realized management was not all it’s cracked up to be and not for him, he decided it was time to seek out a new career as a Nurse Anesthetist, one he had been encouraged to explore for many years by friends who were CRNAs. After completing the CRNA Program at Barry University in Miami Shores, FL in 2002, he worked in private practice as a staff CRNA for a physician owned group for 9 years.

When the opportunity to start his own private practice presented itself, Paul moved to a rural setting providing anesthesia services for the local hospital. After several years as a solo practitioner, a career move to Little Rock, AR was the right call to make. He has worked at the Little Rock McClellan VA Hospital since January of 2014, where he was named CRNA of the Year in 2017.

Paul is a lifelong resident of Arkansas, with the exception of attending his anesthesia program in FL, a state he dearly loves and misses. He is married (Stephany) with four kids and now, grandkids keeping him busy. He also enjoys writing songs and performing with his band, or as a solo act
