Dr. Tomich leads clinical excellence across a two-state region encompassing Maywood, Ill.-based Loyola Medicine and Mishawaka, Ind.-based Saint Joseph Health System, with accountability for patient safety, clinical quality, regulatory readiness, patient experience, risk management, infection prevention and employee health. A doctorally prepared nurse with more than 31 years of registered nursing experience, he holds certification in infection control and board designation as a fellow of the Association for Professionals in Infection Control and Epidemiology. Prior to joining Trinity Health, he spent 13 years at Rush University Medical Center in Chicago, most recently as system director of infection prevention and control, where he led large-scale regulatory readiness, quality improvement and infection prevention programs that achieved more than a 65% improvement in hospital-acquired device-related infections. Dr. Tomich led Ebola and Covid-19 response efforts at Rush, developing a high-consequence infectious disease program and unit, and co-led systemwide Covid-19 efforts that supported a vaccination program reaching more than 100,000 individuals. In 2024 and 2025, three Loyola Medicine hospitals earned or renewed Magnet designations under his regional clinical excellence leadership.
