Nutrition Philosophy

I strongly believe that ALL foods can fit into a healthy lifestyle and I advocate variety, balance, and moderation instead of unnecessary restrictions or crash diets. I don't believe that there is one perfect dietary approach for everyone; rather there are many paths to health and perfection is not an attainable goal for anyone. I meet my clients where they are and find out what personalized nutritional tweaks will be feasible and sustainable to optimize their health.

As a registered dietitian, I use an evidence-based approach to nutrition counseling and stay up to date on the latest research in peer-reviewed journals. I whole-heartedly believe in the scientific method and am not a proponent of unproven fads, detoxes, or cleanses. 

I advocate a minimally processed, plant-based diet, because research has shown that plants have numerous bioactive compounds that reduce disease risk and keep the body operating at 100%. This does not mean that one's diet needs to be exclusively plants -- animals and animal products can absolutely be included in a healthy diet as long as we make room for all of those delicious and nutritious fruits, vegetables, whole grains, beans, legumes, nuts, seeds, and vegetable oils out there!

I believe it's also important to look beyond nutrition when implementing healthy lifestyle changes. Adequate hydration, physical activity, sufficient and good quality sleep, meditation and mindfulness, and stress reduction are all important components to a healthy and balanced life. I work with clients to develop individually tailored plans to improve all of these areas of wellness within my scope of practice. 

I know that while I'm a nutrition expert, my clients are the experts on their own bodies and food preferences and so I believe that it's essential to have a trusting, easygoing, and collaborative relationship in order to work together to achieve and maintain nutrition goals.

Career Path

Hey there! I'm Erin and I love to eat and talk about food! 

I first became interested in the nutrition field while pursuing my undergraduate degree in Psychology at the University of Colorado in Boulder, CO. I found myself drawn to the challenges and complexity of treating eating disorders and immersed myself in books and classes on the topic. After college, I worked as a dietetic technician at a top eating disorder treatment center in Denver, CO and was enamored with the essential role registered dietitians play in helping people improve their relationships with food and supporting their disease treatment. Craving more knowledge and training in this area, I decided to pack up my life and moved across the country to New York City to attend graduate school at New York University. As I pursued my masters degree and completed my dietetic internship (a year-long experiential learning residency in a hospital where aspiring RDs complete clinical rotations in a variety of medical settings to cement their nutrition knowledge in Medical Nutrition Therapy before they can be eligible to pass their board exams), I maintained an active interest in eating disorders through board membership of the International Association for Eating Disorders Professionals, where I met many inspiring and badass eating disorder specialists and gained more expertise about treating eating disorders. Concurrently, I began taking more of an active interest in working with cancer patients, completing an intensive elective rotation in Ambulatory Oncology. I loved that both populations, eating disorders and oncology,  were so complex and required creative thinking, strong clinical skills, empathy, and excellent relationship building to help people overcome their barriers to optimizing their nutrition. After my internship, I was offered a position as an inpatient dietitian where I covered medical, surgery, and oncology units and became even more absorbed in helping sick people improve their nutrition. I then moved into an outpatient oncology setting, where I gained experience working with patients undergoing chemotherapy, radiation treatment, bone marrow transplants, and surgery to treat their cancers. After accumulating the required practice hours to sit for the Certified Specialist in Oncology Nutrition (CSO) board exam, I studied my butt off and became a CSO. I now work at the Laura and Isaac Perlmutter Cancer Center at NYU Langone Medical Center and maintain a small private practice. Every day, I get to meet new and interesting people with diverse backgrounds, talk about food (my favorite topic!),  bust nutrition myths (there's a lot of crazy stuff on the Internet, guys - don't believe everything you read!) come up with creative and individualized ideas to help prevent and manage side effects related to cancer and cancer treatment, and generally feel like I'm making a positive difference in people's lives. It's pretty darn cool to have such a rewarding and fulfilling career!
