20th Century Fox TV’s comedy team is expanding. Sarah Geismer, who has spent the last seven years at Fox 21 TV Studios, will join the comedy development ranks as a VP. She’ll report to Cheryl Dolins, SVP of comedy development.

After graduating from Brown University, Geismer got her start in the business as an associate producer of MTV’s “True Life,” and began life at Fox 21 as an assistant, promoted into the exec ranks by then-Fox 21 president David Madden.

While at Fox 21, Geismer dipped into a variety of genres, helping develop comedies like IFC’s soon-to-conclude “Maron” and FX’s “Sex&Drugs&Rock&Roll,” as well as USA dramas “Burn Notice” and “Graceland” and Fox’s upcoming TV movie “Rocky Horror Picture Show.”

She also shepherded projects like a still-gestating adaptation of Gary Shteyngart’s memoir “Little Failure” (executive produced by “The Americans” showrunners Joe Weisberg and Joel Fields) and a Sheila Callaghan-penned version of “Lena Finkle’s Magic Barrel,” based on Anya Ulinich’s well-reviewed graphic novel about the world of dating as a mom of two teen girls.

“She’s a smart, talented developer with great taste and creative judgement, and the perfect addition to our already formidable ranks,” 20th VP of development Michael Thorn said in a statement.
