Early Life and Background
Katherine Victoria Litwack was born on June 13, 1986, in Bryn Mawr, Pennsylvania, the youngest of five children. Her mother, Ellen Judith Litwack, is a poet and speech therapist, while her father, Gerald J. Litwack, was a molecular pharmacologist and college professor.

As a child, Dennings lived in Penn Cottage, a historic house built in 1694 in Wynnewood, Pennsylvania. She began her career at age 9 by appearing in commercials, and her family did not have much money for formal acting lessons. She worked as an extra to earn her Screen Actors Guild card and took on small jobs to gain experience in the industry.
Dennings was homeschooled for most of her education, with her only enrollment at a traditional school being a half-day at Friends’ Central School. She graduated from high school early at age 14 and moved with her family to Los Angeles to pursue acting full time. She later explained in a 2008 interview with Philadelphia magazine that she chose Dennings as her professional last name because she wanted to keep her personal life private.

Her persistence in auditioning and willingness to take on varied roles allowed her to move into larger projects. This period laid the foundation for her casting in more prominent films beginning in the mid-2000s.
