Jillian began acting when she 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. Before attending Union University to study Theatre Performance, Jillian had the opportunity to study at The Second City and emcee the Illinois High School Improv Festival in Chicago, IL. As an improv artist, Jillian has worked at the Pennsylvania Renaissance Faire, training for 4 months with the troupe We Are Vanessa, and performing in weekly Harold and Armando long-form shows, short-form shows, and hosting an audience-interactive "wet show," called Peebles' Court. She and Laurel George founded Memphis's premiere long-form duo improv comedy group, B&G Improv, in 2019. They performed during Midtown Opera Festival 2019 and Voices of the South Fringe Festival 2019. Jillian appeared on stage at Kismet Improv in Providence, Rhode Island in several improv shows and as a member of the Kismet Marquee Cast, as well as participating in an Improvised Shakespeare showcase hosted by Julie+Juliet at the 2022 Ocean State Improv Festival. On stage, Jillian has performed in over 200 theatrical productions including several regional, national, and world premieres - Byhalia, MS (Playhouse on the Square, 2015), In Search of Tonto Goldstein (Women’s Theatre Festival of Memphis, Inc., 2016), Ricochet (Art with a Heartbeat, 2018), and The Parchman Hour: Songs and Stories of the 1961 Freedom Riders (Hattiloo Theatre, 2019). Her performances in Proof (Theatre Memphis), As You Like It (Theatre Memphis), and The Parchman Hour (Hattiloo Theatre) earned her nominations from the Southwest Tennessee awards organization, The Memphis Ostranders. From 2016-2017 she participated in and successfully completed Tennessee Shakespeare Company’s Teaching-Artist Fellowship, performing in shows such as Romeo and Juliet, Much Ado About Nothing, and Comedy of Errors. She returned to the company briefly at the end of 2017 as an Education Program Artist and Marketing Associate. During 2020's global pandemic shut down, Jillian joined Living Room Shakespeare Company's international cast for an online performance of The Curious Incident of the Dog in the Nighttime, directed by Kevin Anderton. Her work in the film/television industry includes several Indie shorts as well as feature roles in Southland Gaming and Racing commercials, Fresh Big Mouf’s music video I Got What You Need, and work with television series Nashville and Million Dollar Quartet.
"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."
