Dr. Vissa is the senior physician leader for SSM Health DePaul Hospital, overseeing clinical performance, patient safety, quality outcomes, medical staff governance and regulatory readiness. He drives high-reliability care by translating performance insights from Vizient, CMS, Leapfrog and internal dashboards into focused improvement priorities across mortality, length of stay, hospital-acquired conditions, readmissions and patient flow. In 2025, the hospital achieved a 10% improvement in length of stay under his direction through stronger physician engagement, daily interdisciplinary rounds and streamlined throughput processes. The hospital also ranked No. 5 in safety in the Vizient quality and accountability study’s large complex medical center cohort, reflecting sustained harm-reduction and reliability gains. Dr. Vissa is recognized for clear, data-driven leadership that strengthens accountability and interdisciplinary teamwork across frontline clinicians and operational leaders. He previously served as interim president of the hospital from 2023 to 2024, as well as president of the medical staff and chief hospitalist, bringing rare continuity across clinical, operational and executive leadership.
