Banner Health promotes three physicians to new regional medical officer positions


Charlie M. Agee, MD; Marjorie J. Bessel, MD; and Sheldon G. Stadnyk, MD; were named as regional medical officers for Banner Health’s three regional areas of operation – Arizona West, Arizona East and Western Region (Colorado and community-based hospitals in seven states). In addition to taking on added responsibility, the three will maintain their current roles as facility-based chief medical officers (CMO) at Banner Del E. Webb Medical Center, Banner Desert Medical Center and North Colorado Medical Center, respectively.

“With these new roles, Banner’s regions will enjoy the active participation of these physician leaders, and they will also serve as members to the system-wide clinical leadership team. They will have direct supervisory responsibilities over the other CMO’s in their respective regions, as well,” said John Hensing, MD, executive vice president and chief medical officer of Banner Health. “As we move toward fulfilling our vision of a clinical quality company, these positions will be instrumental.”

Dr. Agee, currently Chief Medical Officer at Banner Del E Webb Medical Center, served as the first CMO for Banner Estrella Medical Center after an 18-year career in private practice. There, he was instrumental in developing and overseeing the Professional review committee, medical staff bylaws and opened Banner’s first fully Electronic Medical Record facility. Previously, he served as the Chief of Staff at Banner Thunderbird Medical Center. Dr. Agee is a graduate of the University of Arizona College of Medicine in Tucson and attended medical school at the University of Washington in Seattle and completed his Obstetrics and Gynecology residency at Maricopa Medical Center in Phoenix.

Dr. Bessel, Chief Medical Officer at Banner Desert Medical Center, has been an East Valley physician since 1995, and was previously the CMO at Banner Gateway Medical Center. Dr. Bessel has held an interest in physician leadership since first starting in medicine, seeing it as a way to affect patient care for a broader number of patients than her one-on-one patient days could produce. She earned her medical degree from Rush Medical College of Rush University in Chicago and completed her Internal Medicine residency at Rush Presbyterian and St. Luke’s Medical Center, both in Chicago.

Dr. Stadnyk accepted the North Colorado Medical Center CMO position in March 2009 where he has helped the hospital by advancing their quality efforts as well as assisting with their physician recruitment and development. Prior to joining Banner Health, he served as vice president for medical affairs at Exempla Saint Joseph Hospital in Denver. He led Exempla Saint Joseph in three successful Accreditation Council for Graduate Medical Education (ACGME) reviews for general medical education programs for five years with “commendation” (no citations). A graduate of the University of California Los Angeles David Geffen School of Medicine Residency, he completed his Internal Medicine residency at UCLA Medical Center.
