Ronald J. Keller, CRNA, MS (Retired)


Ron is the founder of Special Anesthesia Services. He is a lifelong resident of Derby, Kansas, as is his wife Carol. She is a pediatric physical therapist, retired from the Derby school district.

Ron is a graduate of Wesley School of Nursing, and Wichita Physicians School of Anesthesia. He received his undergraduate degree from Friends University and his Masters Degree from the University of Kansas. His nursing background was in Coronary Care, and he spent years as an Emergency Medical Technician with the Derby EMS.

Completing his anesthesia certification in 1981, Ron spent the next fifteen years working in the hospitals and ambulatory surgery centers of Wichita, KS. He was a clinical instructor, teaching anesthesia residents, and nurse anesthesia students, as well as serving as the operating room clinical coordinator for Southwestern College and Hutchinson Community College EMICT programs. During those years he spent many weekends providing relief services to fellow anesthetists in rural hospitals around Kansas.

In 1989, Ron also began providing in-office sedation services in Wichita dental and medical offices in his spare time. The demand for high-quality sedation care grew, and Special Anesthesia Services evolved into an anesthesia practice limited to dental offices exclusively.

In their spare time, the Kellers enjoy scuba diving and watching Wichita State athletics. Ron is an avid four wheel drive enthusiast and amateur mechanic, spending nearly as much time under his old jeep as inside it. Ron’s last case with SAS was on Halloween 2015. He’s now in search of the next adventure, and plans on roaming the world with Carol until, as all anesthetists do, he finally “runs out of gas”.
