Liza Gofman
BS in Dietetics
Volunteer
Elizabeth (Liza) Gofman is a second-year grad student at California Polytechnic University, San Luis Obispo. Liza has been with 23 Nutrition Therapy for almost three years, working behind the scenes, writing informative blogs, and collaborating with the team on various projects. A northern California native, Liza got her BS in Dietetics with a minor in Biological Sciences (focusing on Neurobiology) from Arizona State University before moving back to the West Coast to obtain her Master of Science in Nutrition, focusing on molecular nutrition. She is currently completing her Dietetic Internship and supervised clinical practice through various rotations while preparing for the RD exam. While in grad school, she also works on a research study addressing cancer risk prevention with California Wildland firefighters. Her research focuses on nutrition communication, health prevention, and education. Liza is passionate about effective nutrition communication, health prevention, root cause treatment, and hormonal medical nutrition therapy.
While always passionate about health, wellness, and nutrition, Liza became intrigued by functional dietetics and medical nutrition therapy from her own experiences with GI dysfunction. After countless conventional methods proved ineffective, Liza set out to learn more about functional nutrition to take control of her health. With an initial educational background in Neurobiology, seeing the gut-brain connection is what ultimately led her to shift her focus to integrative Dietetics in hopes of becoming an expert in the field. After seeing the available resources, she found her passion in nutrition communication to help educate others to take back their health using evidence and science-based strategies.
Hello! My name is Nisa Zamora, and I am an undergraduate student at UC Berkeley majoring in Media and Global Cultural Studies. As a volunteer intern at 23 Nutrition Therapy, I leverage my media background to create and disseminate evidence-based content that promotes functional medicine and nutrition through videos, social media, and newsletters. My studies at Berkeley have honed my research, communication, and analytical skills, which I apply to make complex nutritional information accessible and engaging for diverse audiences.
My passion for holistic health began early in childhood and was influenced by my Indian heritage and cultural experiences with traditional Indian practices. Caring for a parent with cancer and managing my own chronic illness led me to seek alternatives to conventional medicine. Embracing holistic practices like balanced nutrition, exercise, adequate rest, and meditation transformed my health and well-being, reinforcing my commitment to this functional approach.
As I am just starting my dietetic career, one of the highlights of working with 23 Nutrition Therapy has been the chance to learn from and work alongside a team of volunteers, interns, and practitioners. Together, we enhance 23 Nutrition Therapy’s mission to equip clients with the knowledge and resources they need to understand their bodies and adopt healthier lifestyles. I believe that focusing on the whole person, rather than just symptoms, allows practitioners to transform lives and build a healthier, more vibrant world for current and future generations.
After earning my bachelor’s, I plan to pursue a graduate degree in nutrition and become a Registered Dietitian Nutritionist. I aim to further my expertise with certification from The Integrative and Functional Nutrition Academy (IFNA), blending evidence-based and holistic practices to make a meaningful impact through personalized nutrition strategies.
