Tonia Jackson O'Neill

Tonia O’Neill is an author and longtime health and wellness professional with more than 25 years of experience. After the loss of her son, she wrote her first book, 21 Days: My Story of Finding Peace After an Unspeakable Loss, sharing her journey and the role movement played in navigating grief.

That experience shaped her belief that our bodies can become a steady place when life feels anything but steady. Tonia’s work now focuses on simple, sustainable fitness habits that support real life. She is also the author of The Consistency Blueprint, the first book in her four‑part fitness series.
