GREENWICH, CT — A Greenwich doctor is bringing her medical expertise to television, joining the production team for “Y: Marshals,” a spinoff of the popular series “Yellowstone,”where she advises on medical scenes and even steps in front of the camera herself.

Dr. Karen Soika, who is trained in plastic and reconstructive surgery, and is a wound care specialist and currently a cosmetic surgeon, has been working on the show since early September.

“With the Yellowstone Ranch behind him, Kayce Dutton (Luke Grimes) joins an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence,” the official show logline reads, according to Variety.

The original “Yellowstone” show aired from 2018 to 2024. It won several awards; Kevin Costner notably won the Golden Globe for Best Performance by an Actor in a Television Series – Drama – in 2023.

Directed by Christopher Chulack, best known for his work as the producer on the hit show “ER” from 1995 to 2008, “Y: Marshals” is currently filming season one in Park City, Utah, and is slated to premiere as early as later this year, or perhaps in spring 2026 on CBS.

Soika, a longtime Greenwich resident, moved to Park City during the COVID-19 pandemic, but she often commutes back to her practice in Connecticut.

Known in the Park City area, she was called upon to deliver supplies to what she later found out was the set for “Y: Marshals” at a local filming studio.

After first chatting with someone on-set and explaining that she was a real-life doctor, Soika was encouraged to meet with the casting department. She was eventually hired to play the role of a nurse and other miscellaneous background parts as needed, and she is now the show’s medical scene expert.

“It just sort of snowballed,” Soika told Patch in a recent phone interview about her involvement in the show.

Soika is tasked with making sure medical scenes are portrayed as accurately as possible. For example, she provides guidance on how wounds should look, how patients would be situated in certain scenarios, and how to use medical equipment properly.

She also works with the props department and is constantly advising Chulack.

The new job has come naturally to Soika, who has essentially taught others her whole life. She was a teaching assistant in college and in medical school where she was the main TA for histology and anatomy. She has trained over 3,000 doctors worldwide, and continues to be passionate about teaching

Soika’s work schedule varies throughout the week, but it’s not uncommon for her to spend 12-14 hours on the set on any given day.
