Meet Jill

Jill Fishburn is the proud owner of DEFINE Oakley, a locally loved boutique fitness studio that has been a cornerstone of Oakley Square for over a decade. After ten years in corporate brand management, Jill followed her passion for wellness, community, and connection—taking a leap into entrepreneurship to lead DEFINE into its next chapter. What began as a personal journey quickly became something more. DEFINE was her “happy place,” and when the opportunity arose to take ownership, she knew she wanted to preserve the magic that first inspired her as a member.

Jill’s love for DEFINE started with the Bounce method—still her favorite class today—and reflects her belief that fitness should be both effective and energizing. Whether she’s supporting the incredible team or welcoming new clients, Jill is committed to creating a space where individuals feel seen, supported, and challenged to grow.

A strong believer in holistic wellness, Jill is passionate about helping others find balance in both their physical and mental health. She strives to cultivate an inclusive, uplifting environment where everyone can show up as they are—because at DEFINE, you FIT in here!
