Marissa (Meshulam) Karp, founder + dietitian
Marissa Karp is a NYC based registered dietitian and the founder of MPM Nutrition. Karp has a Bachelors of Science in Nutrition and Dietetics from the University of Wisconsin and a Masters of Science from New York University. Marissa’s career started at the Bronx VA Hospital, where she saw firsthand how a lack of proper nutrition can lead to chronic disease. She then went on to work at Mount Sinai as an inpatient dietitian, where she worked with thousands of patients who were overwhelmed by nutrition. During her time inside hospitals, Marissa began to notice how confused everyone was about nutrition and just how deep all of our relationships with food and body go. This propelled her to start MPM Nutrition, where she has counseled thousands of clients to help them improve their relationship with food and their bodies for good. Find her on instagram.
Avia Goldstein, Associate Dietitian
Avia Goldstein is a NYC based registered dietitian nutritionist and an associate RD at MPM Nutrition. Avia holds a Bachelors of Science in nutrition sciences from Rutgers University and a Masters in Nutrition from Lehman College. Her interest in nutrition started early on when her Grandpa taught her about organic food and antioxidants long before they were trendy. What began as curiosity about food's impact evolved into a deeply personal mission after recognizing the 'mental prison' that food and diet culture can create. Understanding her own complex relationship with nutrition inspired Avia to become a registered dietitian who does far more than track metrics or provide standard nutritional guidance. In a world of conflicting nutrition advice, diet trends, and information overload, Avia helps her clients find clarity and calm. She is committed to helping people ditch 'all or nothing' thinking, simplifying nutrition, breaking down complex health concepts, and guiding clients towards a more peaceful relationship with food and their bodies. Her extensive experience—from inpatient work at Mount Sinai to corporate wellness at a hedgefund—informs a nuanced, compassionate approach. Her work integrates nutrition science, evidence-based practices with mindful eating, addressing not just dietary intake, but body image, emotional wellness, and the complex dance of food and feelings. She believes we all are in a relationship with food, and it's a relationship so worth nurturing! Through her work, she empowers individuals to transform their relationship with food, rediscovering freedom and joy. Find her on Instagram.
Sydney Navid, Associate Dietitian
Sydney is a NYC based registered dietitian-nutritionist and private chef who earned her Master’s degree in Nutrition and Exercise Physiology from Teachers College, Columbia University. She then completed her clinical dietetic internship at NewYork-Presbyterian Hospital. Her love for food and feeding others began in the kitchen, cooking Persian dishes with her mom and grandma. However, it was her own experiences with disordered eating and chronic digestive issues that led her to pursue a career in nutrition and help others reclaim the joy and pleasure associated with the act of eating. Sydney counsels through a client-centered, functional lens to uncover the underlying “why” and root cause of her clients’ concerns. She is dedicated to staying up-to-date with emerging research to provide high-quality, evidence-based care. Together, you will explore a range of topics, from mindful eating and joyful movement to sleep and mental wellbeing with a focus on identifying simple, sustainable habits that will lead to life-long changes. Sydney also knows how challenging it is to eat in a way that makes us feel good physically, mentally, and emotionally. With her extensive experience in developing nutrient-dense recipes, meal prepping for busy individuals, and teaching cooking classes, she supports her clients on their journeys toward becoming confident cooks and mindful eaters. Whether you’re someone who is curious about plant-forward eating or navigating a new health diagnosis, Sydney will work with you to curate nutritionally-tailored meals and make balanced, nourishing eating an enjoyable part of your life. Sydney looks forward to meeting you where you’re at and helping you attain a fulfilled, healthful life.

Risha Malhotra is a current graduate student at NYU in their Masters of Science in Clinical Nutrition & Dietetics program. Risha holds a Bachelors of Business Administration from the University of Wisconsin-Madison.

Through her personal experience, she’s learned that the right nutrition can be a powerful tool in managing chronic disease. She wants to help others find healing through nutrition, just as she did.
