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.
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 use my background in media to support the creation of informative and evidence-based content that promotes functional medicine and nutrition. My focus is on making this information accessible and easily digestible through modern technology and media, utilizing tools such as videos, social media posts, and email newsletters.
Studying Media and Global Cultural Studies at UC Berkeley has equipped me with strong research, communication, and analytical skills that I apply to advance the mission of 23 Nutrition Therapy. My academic journey has also deepened my understanding of how to effectively communicate complex information to diverse audiences—a skill that is invaluable in helping clients understand and adopt healthier nutritional practices.
Being early in my dietetic journey, one of my favorite aspects of working with 23 Nutrition Therapy has been the opportunity to learn from and collaborate with a team of fellow volunteers, interns, and practitioners. Together, we amplify 23 Nutrition Therapy’s goal of providing clients with the tools and resources to understand how their bodies work and lead healthier lifestyles.
From a young age, I’ve been deeply drawn to holistic health and well-being, a passion that stems from my personal experiences and cultural background. Growing up with family members from India, I was introduced early on to traditional practices that emphasize balance, prevention, and the body’s natural ability to heal. These teachings became especially meaningful to me as I cared for a parent with cancer and managed my own chronic illness. Through these experiences, I became increasingly disillusioned with the Western medicine approach that often focuses on merely treating symptoms rather than addressing the root cause of illness.
Searching for alternatives, I embraced holistic health. By incorporating lifestyle habits such as regular exercise, meditation, balanced nutrition, and adequate rest, I’ve experienced firsthand the transformative power of these practices. They’ve not only improved my physical health but also brought a sense of vibrancy and well-being into my life that I hadn’t known before.
This journey has fueled my passion for holistic health, and I’m committed to helping others discover how small, intentional changes in their daily lives can lead to profound improvements in their overall well-being. After completing my bachelor’s degree, my goal is to pursue a graduate degree in nutrition and become a Registered Dietitian Nutritionist. Following that, I plan to get certified by The Integrative and Functional Nutrition Academy (IFNA) to deepen my expertise in integrative and functional nutrition. This path will allow me to combine evidence-based practices with a holistic approach to health, enabling me to make a meaningful impact in the lives of others through personalized nutrition and wellness strategies.
I believe that by looking beyond just the symptoms and focusing on the whole person, we can truly transform lives and create a healthier, more vibrant world for ourselves and future generations.
