I am a Family Nurse Practitioner, recently retired. My experience includes working in a Headache Specialty Practice, Family Practice and Occupational Health. I have a Plant Based Nutrition certificate from eCornell and the T. Colin Campbell Center for Nutrition Studies.

I have followed a whole food, plant based diet for the past several years and think this is an important cornerstone of a healthy lifestyle. Working with headache patients, I focused on lifestyle factors. This includes getting adequate sleep, engaging in regular exercise, maintaining adequate hydration, managing stress and eating a healthy diet.

The CHIP program includes all of the factors noted above in managing a healthy lifestyle. This is an excellent program to help individuals learn how to take control of their health. I am pleased to be participating in this exciting new program in our area.

Health Coach

Read more about Darcie Johnson

Starting in February, 2015, I removed all symptoms from both diagnosed osteoarthritis and a 24-year difficult struggle with fibromyalgia by removing sugar, flour, most processed foods and eating lots more whole, fresh vegetables and fruit. Pretty naturally in this process, I lost 25 lbs. I am 64, and I have to say it…I look and feel awesome!  I know, first hand, the power of eating whole, plant-based food.  By choice, I now eat 99% whole-plant based diet but still not yet willing to give up  ½ & ½ in my decaf coffee! I feel no need to be perfect but my quality of life has soared by changing my diet. I have a wonderful man in my life, am an active member at the Rochester Zen Center, have 2 dachshunds and live in a cute little bungalow in City of Rochester. Life is good.

Read more about Sue Taylor

In 2011, the Forks Over Knives documentary convinced me that plant-based was the way to go. My journey started with Dr. Ted Barnett’s course:  A Plant-Based Diet: Eating for Happiness and Health, in conjunction with the support and camaraderie of the  Rochester Area Vegan Society co-coordinated by Ted and his wife Carol.  I was inspired to become a plant-based Health Coach and consequently took The Institute of Integrative Nutrition’s Health Coach Program, whose focus is on the whole person, not just diet.  This is in keeping with the CHIP program focus. To further my knowledge I took Dr. T. Colin Campbell’s Certificate Course in Plant-Based Nutrition through eCornell. I have also completed the Forks Over Knives/Rouxbe Plant-Based Cooking Course. I am a member of the Association of Drugless Practitioners (AADP). I am passionate about all aspects of this lifestyle and look forward to furthering the health benefits of all of CHIP’s participants.
