His character's tenure on "Chicago Fire" had ended, but Jeff Hephner wasn't quite finished playing Jeff Clarke. Instead, the former marine became a medical student on "Chicago Med" for 16 episodes. Once he finishes school, Jeff finally leaves both shows, and seemingly the franchise, to take up a residency in Hawaii.

After departing the One Chicago franchise in 2017, Hephner has continued to work steadily, mainly in television. He has a recurring role on Season 2 of "Mars" as Kurt Hurrelle and also co-starred in the short-lived series "Our Kind of People" and "Almost Family." His film roles also include "Peppermint" and "The Shuroo Process."

Most recently, Hephner has been featured in "Power Book II: Ghost" as major antagonist Detective Whitman, and he has a recurring role in "For All Mankind" as Sam Cleveland. For his part, the actor, in a Backstage interview from 2019, credited his success to never giving up, even after facing consistent rejection: "If you're going to do this [acting], you've just got to do it ... [But] if you keep doing it, things will just balance out, and I think that's keyed on persistence."
