Caitlyn Castiglione, RD

Caitlyn Castiglione, RD

Dietitian
41 John St, Babylon, NY
Caitlyn offers personalized, evidence-based nutrition advice, combined with a well-rounded clinical background. She completed three years of nursing training before deciding to focus exclusively on nutrition and earned both her Bachelor’s and Master’s degrees in nutrition from Long Island University. Her personal experience with recurrent SIBO prompted her to actively seek solutions through a combination of self-directed learning and evidence-based research. In the process, she developed a passion for nutrition and its vital role in preventing and managing chronic disease. Her firsthand experience gave her insight into how deeply gut health and nutrition can impact the entire body—an understanding that continues to shape the way she cares for her patients today. Counseling Style: Caitlyn approaches care with the belief that patients are the true experts on their own bodies. She takes a holistic approach that looks beyond just the food on their plate. Caitlyn works collaboratively to create a space where patients feel understood and empowered to make informed choices and develop strategies that fit their lives. She leverages her expertise to help patients make sense of their body’s signals and feel confident in caring for themselves. Hobbies/Interests: Outside of work, Caitlyn enjoys reading, staying active, and developing new recipes in the kitchen - often experimenting with ways to make nourishing foods both delicious and approachable.
