Fortified Performance is so much more than a business. It’s a network of fitness and wellness professionals that work together to help YOU achieve your optimal wellness. Marisa founded Core Principles Performance in 2008. Her initial vision was a small sports massage and personal training studio. Little did she know what would eventually unfold. 10 years later, Forti is now proud to launch Fortified Performance. This embodies all she stands for. Her 4 Core Principles: Strength, Endurance, Flexibility and Massage.

  • These 4 pillars define FORTIFIED PERFORMANCE. With 10+ years experience in the fitness industry, she offers a unique blend of modalities to meet the needs and personalized goals for every client.

    “As a Trainer, Coach and Therapist, I have been blessed to help transform the lives of my clients. Whether it be completing their first triathlon, helping an athlete recover from an injury or working to improve flexibility – it’s been an incredible ride so far.”

    Marisa is a 2X Ironman, has completed several marathons and long distance bike rides. In addition to triathlon Marisa enjoys playing golf and spending time with her family and 2 kids.
