MEET THE FOUNDER

Marissa Karp is a New York City–based registered dietitian, founder of MPM Nutrition, and a trusted voice in the wellness space. 

Her love of nutrition began early—while other kids were reading Harry Potter, Marissa was flipping through Eat This, Not That, captivated by the science behind food. That curiosity eventually led her to become a dietitian, and her own experience with disordered eating shaped her inclusive, down-to-earth approach. Marissa believes that good nutrition is the key we’re all given to unlock our healthiest lives—and that healing your relationship with food starts with compassion, not restriction.

At MPM Nutrition, Marissa and her team specialize in gut health, chronic conditions, and body image distress, taking a holistic, personalized approach that goes beyond what’s on the plate. She helps clients unlearn diet rules, reconnect with their bodies, and find a rhythm with food that feels good and sustainable. Trained in mindfulness-based eating, Marissa blends science with real life—because we believe in kale... but also cake.
