Rheagan began her television career as a child on Walker, Texas Ranger and went on to memorable roles on Malcolm in the Middle, That’s So Raven, 7th Heaven, ER, and many more.
 

Her acclaimed solo show, STAGE MAMMA: From Child Star to Leading Lady (winner of the "Best One-Woman Show" award at the 2026 United Solo Theatre Festival in New York City) premiered at the Zephyr Theatre in the 2025 Hollywood Fringe Festival to standing ovations, rave reviews, and two regional BroadwayWorld Award nominations for Best Solo Production and Best Solo Performance. It was also an Official Selection of the 2025 Binge Fringe Festival at the Santa Monica Playhouse, Fort Worth Fringe 2025, the 33rd Annual Los Angeles Women’s Theatre Festival, and Fallout Fringe Las Vegas 2026. Rheagan will bring STAGE MAMMA back to United Solo in New York City in the fall of 2026.

As a filmmaker, her 2024 short film Subjugate received multiple honors, including Best Women’s Empowerment Film at the 2025 London Women’s Film Festival and a Best Human Rights Short nomination at the LA Independent Women Film Awards.
 

Rheagan's most recent film project is WELL(NESS), a 40-minute female-led dramedy about women, wellness, and the "price" of inner peace. Currently circulating through film festivals across the country, WELL(NESS) has won seven awards in its first three festivals, including Rheagan's Vanguard Award for Best Actress in a Featurette at the 2026 Idyllwild International Festival of Cinema. ​

Rheagan is also a founding member of Ripple, a collective of activist filmmakers dedicated to amplifying marginalized voices through storytelling. Ripple engages communities via an interactive Twitch channel, where audiences actively participate in writing, editing, and shaping resistance-focused narratives, driving progressive conversation and social change. ​​

Whether on stage or screen, in comedy or drama, Rheagan’s work is rooted in resilience, authenticity, and a deep belief that storytelling is the most important and powerful tool for human connection, and that through human connection, we find hope.
