Marisa Michael has been a registered dietitian for 22 years. She holds a master's degree in sports nutrition, the International Olympic Committee's Diploma in Sports Nutrition, and is also a Board-Certified Specialist in Sports Dietetics. She owns a private practice in Portland, Oregon where she does one-on-one consultations, workshops, and freelance writing. She also serves on the USA Climbing Medical Committee.

Marisa grew up enjoying the outdoors and jokes that she can only do "REI sports." Exercise is her hobby, and she regularly enjoys paddleboarding, skiing, climbing, and triathlon. Her practice is based on evidence and science, married with honoring her clients' experiences, food preferences, and intuitive eating. She helps clients find ways to fuel their health and activities in gentle ways that make sense to them. There are no juice cleanses or pantry cleanouts - only actionable, useful information that fits into a person's goals and lifestyle.
