Leo Rosen-Fischer, Masters in Nutrition & Certified Nutritionist 

Hi there! I am Leo, a nutritionist and health coach located in Portland, but I travel throughout Oregon and Washington State to do home visits and presentations. I have my Master's in Nutrition/Dietetics and I am also a registered and certified nutritionist in Washington/Oregon State. On the side I do rock climbing and old-growth tree climbing instructing in cooperation with the state park system. Check out my climbing business But back to nutrition! I love nerding out about the science and research behind nutrition, it is an extremely powerful health tool overlooked by too many of us and our health care system. I keep updated on the latest information and research to bring you the best advice and results! I look forward to working with you :)

What is Nutrition/Dietetics?

Nutrition and dietetics is the branch of knowledge concerned with the diet and food, and its effects on health or growth. Especially with the practical application of the science and art behind understanding the role of nutrition in human health and disease. It is my mission to help people to achieve their health goals and reverse or prevent disease states with nutrition.

Did You Know?

That 90% of chronic diseases, like diabetes and heart disease are preventable with nutritional lifestyle choices and that dietary/nutritional risk factors are the number one contributing cause of death in the U.S. (1)(2)
