Our Instructors

Arc and Oak Pilates was founded by Cristina Porter with a simple, powerful goal: to bring premium, high-quality fitness straight to Marshall and our neighboring rural communities. After working closely with local residents in community spaces, Cristina recognized a real need for a welcoming, low-impact exercise studio that leaves people feeling strong, confident, and cared for.

She envisioned Arc and Oak as a true multi-generational sanctuary a place where local college students can challenge their stamina, beginners can learn without intimidation, and seniors can safely maintain their balance and mobility for life. For Cristina, this studio is about more than just workouts; it’s about building a supportive, down-to-earth community where every single neighbor feels uplifted.
