Mary Zittel, PA-C
Mary brings a deep passion for lifestyle medicine and whole-food, plant-based nutrition to our practice, where she offers nutrition-focused consultations. A graduate of Yale School of Medicine’s PA program — where she graduated top of her class and helped develop the lifestyle medicine curriculum — Mary pairs clinical training with the transformative power of therapeutic nutrition.
Her Story
Mary grew up the oldest of two children in a small town outside of Buffalo, NY. Raised by parents who grew up on farms, she was fortunate to have an upbringing that included growing their own food, cooking from scratch, and working hard outside on the land. The health benefits she saw as a result of this lifestyle planted a seed that would be cultivated years later.
Her love of medicine was nurtured by running around her mother’s medical practice in their small town. Mary spent every spare moment at the family business, eventually following in her mother’s footsteps to become a medical provider. In addition to working in our practice, Mary is blessed to now care for patients alongside her mother in their private, primary care office in their hometown.
A pivotal moment came during her freshman year of high school, when she attended a guest lecture by Dr. T. Colin Campbell. From that day, she fell in love with an unprocessed, whole foods, plant-based way of living and never looked back.
Education & Training
Mary graduated from Canisius College with her bachelor’s in biology, then graduated top of her class from Yale School of Medicine with her Master of Physician Assistant Studies. While at Yale, she helped develop the lifestyle medicine course, which included her thesis on the power of an exclusively whole foods, plant-based diet.
Her passion for healing through lifestyle changes led Mary to work at True North Health Center in California, where she witnessed the power of water-only fasting, as well as what a salt-, oil-, and sugar-free plant-foods diet can do for the diseases that plague so many people.
Her Approach
Mary’s nutrition consultations focus on food as the starting point — helping patients understand how what they eat shapes metabolism, inflammation, digestive health, and energy. Her guidance draws on whole-food, plant-forward nutrition, including salt-, oil-, and sugar-free strategies where appropriate, along with education on fasting and metabolic health.
Her approach is personalized and practical. Rather than prescribing a single template, she works with where you actually are — your preferences, your constraints, and your goals — to build eating patterns you can genuinely sustain.

Mary resides outside of East Aurora with her parents and two dogs, Lottie and Maggie, who enjoy roaming the acreage and helping “mom” in her vegetable garden. In her spare time, she spends her days gardening, tending her orchard, sewing, knitting, reading, traveling, and being physically active. She especially enjoys her morning walk outside, where she can be at one with nature.
