Marina Kerekes (née Horiates) is an American theatre, film, and television actress based in New England. In addition to acting, Marina is a writer, a singer, a director, a bookworm, a yogi, a proud Greek-American, and a physician. After graduating medical school from Johns Hopkins School of Medicine, she decided to instead pursue the medicine of art, and she has returned to a career of storytelling in all forms.

Selected credits from some of her favorite stories include Claudia Draper in Tom Topor’s play Nuts (Actors Gym & Talent, dir. Reno Venturi), Emily in the film Goodnight, Gracie (GirlRyan Productions, dir. Fiamma Piacentini), Altagracia in Edwin Sanchez's Icarus (Yale Dramatic Association, dir.

She stars as Anna Carole alongside Michael Emery and Jackson Deen in the newly released Gary Fierro film Mightyclaw, and she will appear in the supporting role of Madame Xena in the upcoming Brandon Golden & Samuele Bergamini film New York Mouse (Project 10K Films). Another highlight of 2025 included her performance in the lead role of Oakie in Laura Thoma’s new play Letter to My Soul (dir. Carin Estey), which was commissioned by the Guilford GreenStage Arts Festival.

In addition to her acting career, Marina continues to work as a medical content editor on physician-authored educational and clinical practice resources, and she’s enjoyed consulting on feature-length screenplays to ensure medical accuracy without sacrificing story.
