For years, I struggled with my weight, body image, and constant GI issues. Doctors labeled it as IBS, but the advice was vague—“cut out certain foods” or “manage stress.” At the same time, I was stuck in the binge-restrict cycle, trying every diet out there, hoping something would finally work. But no matter what I did, I always ended up back in the same frustrating place.
Then I realized—I wasn’t alone. So many others were dealing with the same frustrations, feeling like their bodies were working against them. That pushed me to study nutrition and dig into the science of how our bodies actually work—how digestion, metabolism, hormones, and emotions all play a role in our health.
That’s why I started One Nutrition Group. Because nutrition isn’t just about what you eat—it’s about understanding your body, feeling in control of your choices, and finding real solutions that last. No guilt, no extremes, no more guessing. Just a sustainable, science-backed approach designed for you and your life.
Danielle takes a realistic, compassionate, and science-based approach to nutrition. She believes that understanding the why behind our food choices is key to making lasting changes. She works with clients using a whole-body approach, recognizing that how we think and feel can affect everything from digestion and metabolism to our relationship with food.
Her counseling is rooted in science, but more importantly, it’s built to work in real life. This isn’t about quick fixes or fad diets. Danielle helps clients create sustainable, personalized strategies that support their physical health and strengthen their relationship with food for the long term.
Danielle earned her Master’s degree in Clinical Nutrition and Dietetics from New York University. She completed her clinical training at NYU Langone Health Hospital, Perlmutter Cancer Center, and BALANCE Eating Disorder Treatment Center.
She has worked across a variety of outpatient settings, providing nutrition counseling to individuals, families, and groups. Danielle has supported clients of all ages, from children to adults, helping them improve their relationship with food, manage chronic symptoms, and build habits that support sustainable weight loss.
Outside of her clinical work, Danielle is passionate about advocacy and giving back. She has volunteered for the National Eating Disorders Association Helpline (NEDA) and created a fundraiser through Project HEAL to support access to eating disorder treatment.
I’ve had such an amazing experience with One Nutrition Group! Erica Kessler is so great. She takes the time to understand your lifestyle and helps you build healthy nutrition habits that actually fit into your existing routines. I love her approach of focusing on adding nourishing foods rather than taking things away…
Erica was the first nutritionist I’ve ever worked with, and right from the start, she made me feel heard and comfortable. She asked thoughtful questions, was so genuine, and never made me feel judged…
