As a dietitian, I’m very thoughtful about where I refer clients, and I have complete confidence in Tribeca Nutrition. Their team provides personalized, evidence-based nutrition counseling in a supportive and judgment-free environment. They are especially skilled at helping clients build a healthier relationship with food through intuitive eating and compassionate care. It’s an excellent practice and one I’m always happy to recommend!

I've worked with Rebecca since 2018, and have consistently experienced her as a creative, thoughtful, and detailed oriented provider. We've shared a suite together, and I love listening to her laugh with her patients all day. Rebecca does clinically difficult work in a joyful, loving, authentic way.

Rebecca and her team at Tribeca Nutrition are incredible and always a top referral for me! As an eating disorder dietitian myself, it is so important to have providers that you can trust. Rebecca is an incredible weight inclusive and eating disorder specialized RD. I highly recommend her and her team for any clients looking for a dietitian that is anti-diet and non-judgmental!

I had the opportunity to collaborate with Rebecca on a particularly challenging case, and the experience was both productive and rewarding. Rebecca is a highly competent nutritionist who brings a thoughtful, evidence-based approach to her work. She takes the time to consider the full clinical picture and communicates clearly and effectively with colleagues. What stood out most was her empathy and genuine care for the patient. Rebecca approaches each case with compassion while maintaining a high level of professionalism and clinical rigor. Our collaboration resulted in meaningful progress, and it was clear that her insight and dedication played a significant role in that outcome. I would welcome the chance to work with Rebecca again and would confidently recommend her to both patients and fellow clinicians.
