Mary Ruiz-Personal Trainer
Hello! My name is Mary, and I’m a personal trainer who is passionate about helping people build sustainable habits that not only help them reach their goals but also maintain them long-term. With a background in education, I hold a Master’s degree in Educational Leadership, and for several years I worked as a middle school teacher. Fitness has always been a big part of my life, but it wasn’t until 2020 that I truly dove into my fitness and weightlifting journey.
