Constance Coquillette, LCSW—Integrative Health Coach

“There is nothing more rewarding than seeing patients feel better.”

In my practice, we are all living a plant-based lifestyle and are models for the patients in our own great health outcomes. There is nothing more rewarding than seeing patients implement changes and feel better as their health improves.” She has used motivational interviewing techniques to help patients take steps toward a plant-based diet and away from the standard American diet.

As someone who guides individuals through their transition, I found the T. Colin Campbell Plant-Based Nutrition Course was not only a fantastic way to affirm my knowledge of those benefits through concrete data, science and research, but also to highlight and clarify the dangers associated with the consumption of animal-based foods.”

After losing her 53-year-old mother to breast cancer, she discovered that food could be the key to helping people.

Andrea Seppinni is a classically trained chef who shares her passion for a WFPB lifestyle on and during her cooking classes. “I always understood the importance of knowing where one’s food comes from and how it’s prepared, especially since losing my mom to breast cancer when she was 53.
