I am no longer in private practice.   This website is currently in transition but will continue to act as a platform for blogging, videos and a history of my various activities. You are welcome to get in touch with me at but I will not be able to offer any nutritional counsel. You can also check  My YouTube Channel for some humorous and educational nutrition nuggets!
PERSONAL STATEMENT: My nutrition counseling philosophy is one I consider truly holistic: looking at the whole person and figuring out  what works for you as an individual. I’m not here to tell you what you should do, but rather will educate, inform and hopefully inspire you to eat the foods that are right for your body starting with the steps for which you are most ready, willing and able to take. I will support and encourage you to make changes that are realistic and beneficial for your health. I take a comprehensive look at all aspects of your life to help understand how we can collectively come up with recommendations that will get you started on your goals to improved health.
