We are excited to announce that Bözse Soltész is joining Flatstone Grove.

The award-winning Hungarian actress has appeared in numerous stage productions ranging from operettas and musicals to dramas. A mother of two herself, she believes that playfulness provides a healthy life: “Don’t take anything too seriously,” she says. “If you do, you lose joy in life.”

Her rich voice is the perfect fit to tell the stories of Flatstone Grove.
