Kelly began her career with OSF Healthcare in 1998, progressing from a registered nurse at the bedside to president. She has worked in several areas across the OSF Healthcare System including OSF Saint Francis Medical Center in Peoria, IL, as a registered nurse in general pediatrics and in neonatal intensive care and as a registered nurse and 6 sigma black belt for OSF Medical Group in Peoria, IL. In 2007, she accepted a master black belt position at OSF St. Francis Hospital & Medical Group and moved her family to Escanaba, MI.

“Prior to moving here, my family and I vacationed in the Upper Peninsula for many years and had fallen in love with the area. When the opportunity presented itself, we jumped at the chance to make the move. We consider it a tremendous blessing to live here.”

A native of Canton, Ill., she received her nursing diploma from Graham Hospital School of Nursing in Canton, IL and a Master of Science in Nursing from Walden University.

In 2015, Kelly moved into the vice president of operations role. Her experience working in clinical care and performance improvement helped her develop an in-depth understanding of many aspects of the healthcare delivery system. This knowledge contributed to her ability to plan and effectively execute on key systems and processes and made for a successful transition into the position. In January 2022, Kelly made another successful transition, assuming the role of interim president. 

“I am always ready to take on new challenges and have been so fortunate throughout my career with OSF to grow and take on new positions. I truly consider it a privilege to serve with the Sisters in providing healthcare in our community.”

Kelly lives in Gladstone with her husband, Brett, daughter, Olivia, and two dogs. When not working, she enjoys engaging in outdoor recreations with her family including hiking, backpacking, kayaking, biking and snowshoeing. Kelly is also active in her local church and enjoys volunteering at various fundraising events and local charities.
