He also guided the hospital toward Accreditation Council for Graduate Medical Education approval of a family medicine residency, with an internal medicine residency and academic community hospital designation expected in 2027. He has also prioritized workforce stability, cutting agency spending by more than 50% in two years and reducing nursing turnover to 10-12%. He founded the Ingalls Leadership Circle, a 12-month mentoring program for mid-career leaders now in its third cohort.
