Case Studies

Southern Illinois Healthcare

Together with SIH leadership, The Croes~Oliva Group created a physician practice that, years after rollout, continues to be flexible in operation and strategic in vision.



“The Croes~Oliva Group’s expertise was essential to fulfilling our vision for the new Southcoast Center for Primary & Specialty Care. Their knowledge and strategic insights commanded the attention and respect of every stakeholder. They helped to create a united, multi-specialty group of practices and services that will improve coordination of outpatient care. Their roadmap will serve as a blueprint for our future ambulatory care centers.”
