Mari Petherbridge

Owner / Instructor

Mari Petherbridge is the owner of Modern Nutrition & Pilates, a boutique wellness studio in San Rafael offering private, duet, and small-group Pilates training, holistic nutrition, and wellness education.

After dancing pre-professional ballet for 15 years, Mari’s path shifted when a serious ankle injury ended her dance career and led her to Pilates. It was the first form of movement that helped her build strength without worsening pain, and that experience continues to shape the way she teaches today.

Mari specializes in individualized Pilates for injury recovery, pain management, posture, strength, and functional movement. Her approach is precise, supportive, and highly tailored to each client’s body, goals, and needs. As the studio has grown, Mari has built Modern Nutrition & Pilates as a professional collective of skilled instructors who share her commitment to personalized training.

Mari is also a Holistic Nutrition Consultant trained through Bauman College. Her nutrition work focuses on whole foods, lifestyle habits,  education, digestion health, blood sugar regulation, inflammation, hormone support, and sustainable changes that support long-term wellness. She also offers nutrition education and wellness talks for community groups, professional organizations, and in clinical settings.

At the heart of Mari’s work is the belief that pain is information, the body is always communicating, and both movement and nutrition can be powerful tools for healing. Through Modern Nutrition & Pilates, she helps clients move better, feel stronger, and craft a lifestyle that keeps them doing what they love longer.
