Early Life and Education

Jessica St. Clair is now 48 years old and was born on September 21, 1976, in Princeton, New Jersey, where she began her life before eventually moving into comedy and performance.

She was raised in Westfield, New Jersey, where she attended Westfield High School and graduated in the class of 1994, showing early signs of her creative talents. After high school she studied at Middlebury College in Vermont, a liberal arts institution that encouraged her intellectual and artistic development during her college years.

Her time at Middlebury College preceded her moving into comedy, especially with the Upright Citizens Brigade Theatre, where she developed the improvisational and sketch comedy skills that would become central to her career.

In 2015 she was diagnosed with breast cancer and underwent treatment including chemotherapy, a difficult period that tested her resilience and changed her perspective on life and work.

In a turn of events, her husband was diagnosed with colon cancer around the same time, creating a dual health crisis for the family that they faced together. Both have since gone through treatment and recovered, and they have spoken publicly about their experiences to raise awareness and support for cancer patients.

These health struggles have been incorporated into her creative work; for example, Playing House included a storyline where her character also receives a breast cancer diagnosis, bringing authenticity and emotional depth to the show.
