She participated in high school and community plays and productions, competed with her high school forensics speech team, was cast in Southern Illinois University McLeod Playhouse’s Summer Theatre production of Aida, and was one of 12 twelve members of the 2009 Illinois All-State Improv team.

Jillian relocated to Providence, Rhode Island with her husband and three cats during the summer of 2021.

"The relationships in Proof are emotionally raw, and excruciatingly real. Before she says a word you can read the fatigue and depression in Barron's posture, as she putters around the backyard of her family home." (2013)
"Jillian Barron, who plays Laurel, [Evan] Linder's female protagonist, is especially strong here. Barron, it seems, can do no wrong. She was one of the more fantastic things about Jo Lenhart's fantastic As You Like It at Theatre Memphis. She followed that with an award-worthy turn as a talky millennial in Rapture, Blister, Burn in the same space. Her Laurel doesn't always make good choices but she's always trying (sometimes failing) to choose better. She owns her worst mistakes - eventually - and she learns from them, kinda. She's flawed but decent, and constantly awkwardly evolving. It's a terrific role on the page and Barron wears the character like school colors." (Byhalia, MS 2016)
"Jillian Barron plays the hardboiled detective and brings a fierce anime edge to her scenes." (The Nether 2018)
"Jillian Barron is joyfully weird as the geographer. She's one of those eternally chipper people that seems to love her job - and maps - just a little too much." (The Typographer's Dream 2018)
Jon W. Sparks, The Commercial Appeal, Memphis Magazine
"Proof is beautifully performed, particularly with Jillian Barron as Catherine. Barron's instincts are dead-on with every bit of sarcasm, panic, fear, hope and resolve emerging with unforced authenticity. This is her first time with Theatre Memphis, and let's hope for more." (2013)
"But what really makes [Rapture, Blister, Burn] pointed is the presence of Avery (Jillian Barron), a 21-year-old free spirit who has her generation's blindness to the past but is assured about what her future holds...Barron hits a bullseye with her gift for portraying an authentic know-it-all college kid who understands everything except what she doesn't." (2015)
"Jillian Barron finds the core of the new mom and makes her three dimensional, simultaneously earning sympathy and disapproval." (Byhalia, MS 2015)
