What is Nina Siemaszko's net worth?

Nina Siemaszko is an American actress who has a net worth of $500 thousand. Nina Siemaszko is recognized for her nuanced performances across film and television, particularly during the 1990s and 2000s. Known for her expressive naturalism and intelligence on screen, she has played a variety of strong, grounded characters in both studio features and acclaimed TV dramas.

Born Antonina Jadwiga Siemaszko on July 14, 1970, in Chicago, Illinois, Nina grew up in the same creative family as her brother Casey Siemaszko, a respected character actor known for "Back to the Future" and "Young Guns." Their father, a Polish resistance fighter, and their English mother instilled in them a sense of determination and artistic curiosity that carried into both siblings' acting careers.

Nina trained at the Goodman School of Drama at DePaul University and made her feature film debut in the John Hughes production "One More Saturday Night" (1986). She went on to appear in "License to Drive" (1988), "The American President" (1995), and "White Squall" (1996), as well as several acclaimed television projects. She played key roles in "The West Wing," "Grey's Anatomy," "Castle," and "The Fosters," earning respect for her subtle, grounded portrayals.

Like her brother Casey, Nina has maintained a career marked more by craft than celebrity. Together, the Siemaszko siblings have quietly built a shared legacy in Hollywood as talented, enduring character actors whose work continues to resonate with audiences.
