He recurred on hospital series, legal procedurals, and event miniseries, often cast as retired or active military leadership, reflecting his ease with structured hierarchies and institutional protocols. Throughout this period, he avoided long-running daytime serials, focusing instead on limited runs and prestige formats that aligned with his established brand of controlled, professional intensity.
