Michelle listened to my needs, what my triggers were for disordered eating and created a plan that worked for me. Never once did I feel restricted, judged, or frustrated. She created a plan that is sustainable for the rest of my life. No gimmicks, eating trends or hype.


Overall, I would highly recommend Michelle to anyone who is serious about improving their health and fitness. Her personalized approach, attention to detail, and commitment to helping her clients succeed make her stand out as one of the best nutritionists around.

“Working with Michelle was a great experience. She’s super knowledgeable and patient! I’d recommend her to anyone looking to optimize their nutrition.”

Richard R, Boston, MA

"Michelle is great! I have worked with her for a few months to set a foundation for healthy eating without sacrificing normal living. Michelle also worked with me to create a plan for my half marathon to fuel the week prior, during the run, and after. I felt so good during this experience, and I really attribute that to her guidance."

Jessica S, Boston, MA

"I started working with Michelle with the intention of changing my eating habits and making sustainable lifestyle changes. I had tried a number of different diets (Whole30, elimination diet, Noom App, macros counting) but nothing seemed to fit my needs in the long run. Michelle really took the time to understand my goals and needs to then craft a plan that fit a healthier lifestyle. I was able to work towards my fitness and health goals all with seamless integration into my life. I highly recommend Fuel2Live Nutrition!"

"Michelle is a very skilled clinician. Since I started working with her, I feel more empowered to take control of my personal health and learn how to use nutrition to care for my body’s physical demands. I appreciate how person-centered she is. Her coaching style is a nice balance of compassionate, nonjudgmental, and pragmatic. I feel like I walk away from our sessions with clear achievable goals and a plan for what to work on as a next step. "
