Her greatest passion lies in leading Teacher Trainings in Mat, Reformer, Tower, and Chair Pilates—something she has been devoted to for the past 7 years through various companies and now through Pilates Thierry LLC.
Ashley’s training programs are designed to cultivate some of the most established and successful instructors in the industry. Many of her graduates have gone on to become top instructors throughout California, while others have opened their own studios or launched their own businesses.
Beyond teaching, Ashley invests her spare time in mentoring her graduates—coaching them on how to navigate the Pilates industry, introducing them to studios, and building connections to ensure they have opportunities to interview and succeed. She is deeply committed to community building, organizing photoshoots, events, and retreats that foster both personal and professional growth.
Ashley currently teaches 15 Reformer Pilates classes per week at House of Core in Brentwood, a studio she has come to love so much that it is now partnering with Pilates Thierry LLC to host the next round of trainings in 2025.
Her trainings are in high demand, typically selling out within 48 hours of announcement and often building a waitlist of 10 or more.
