Rod McFadden, CRNA

Rod received his Bachelors Degree in Anesthesia from Southwest Missouri State University and completed his anesthesia training from Southwest Missouri School of Anesthesia in 1978. Following a brief stint providing anesthesia in Monroe, LA he worked for six years as a staff anesthetist and clinical instructor for PAS, Inc./Southwest Missouri School of Anesthesia. That was followed by six years employed by Ozark Anesthesia Associates at Cox Medical Center primarily providing cardio-thoracic anesthesia.

Rod became self-employed in 1990 and formed a corporation – M & M Anesthesia, together with his wife Dona, also a CRNA, to provide anesthesia services for N.E. Texas Medical Center until 1992. He next formed a locum tenens agency to provide relief services in anesthesia. The next 14 years were spent traveling from coast to coast, from Alaska to New York providing that service. The exposure to so many good people within the industry and the variety of anesthesia practice has been extremely beneficial to Rod in his anesthesia skills.

Although he enjoys his travels, Rod is exceedingly happy to have found a home within the family that is White River Anesthesia Associates.
