He recently opened up about his time on the program in an interview with Looper, and reflected on the big change following actor Mark Harmon’s departure.

“On a personal note, I’m really thankful I got to work with Mark and call him a friend for that many years,” he said.

“I feel similarly about everybody I’ve worked with there. It’s been a wonderful, wonderful place for 20 years. As people come into our set and people go, it feels like you’re making new family members and you’re making new friends all the time,” he added.

On not having Mark on the show, he described it as a “massive change”.

Could Mark Harmon return to NCIS?

“This whole television show has been built on the backs and the effort and the work of people like Mark Harmon, like Cote de Pablo, like Michael Weatherly, like Pauley Perrette. There’s a lot of people that have made this thing the entity that it is, that have served their time, or however you want to put it. They’ve been family members, and Mark has certainly been the patriarch of this family for 19 solid years,” he said.

“You feel that loss right away on an energy level, but also on a personal level day to day.”
