Hey, I’m Lexy!

I’m a Registered Dietitian Nutritionist in Boston, MA with a non-diet, intuitive eating approach. I help people heal and transform their relationship with food and their bodies to live their best lives and feel empowered.

It’s my absolute passion to help you feel better with food and your body so you can focus on more important things in life like chasing your dream job, falling in love, and saying YES to the life you want.

But real talk, I’ve been there. I get it. It sucks.

I oscillated between restrictive diets, juice cleanses, detoxes, self-imposed arbitrary nonsense food rules, bingeing, and feeling out of control with food. I had anxiety around what, how, and when I “should” eat. I know the frustration, anxiety, stress, overwhelm, confusion, fear, and annoyance that comes with the process of always being “on” or “off” with food. 

I’m also a sober alcoholic (since March 17, 2014, woo hoo! you can read my whole recovery story here) and this adds to my very deep (like… to my bones deep) personal understanding of what it’s like to self-soothe, control, let go, escape, and use food and other substances to feel better. I understand on a very deep level that I feel many healthcare providers don’t. 

I help my clients unlearn arbitrary food rules, identify roadblocks to self-trust, and eliminate harmful dieting habits so they can fully trust and respect their body and experience joy and peace around food.

I’ve developed a program and process that provides REAL, lasting transformations in how people approach food, their bodies and therefore their lives using a combination of my own experience, professional education, 10 years as a Registered Dietitian Nutritionist, and time spent in both food and alcoholism recovery. 

I’m thankful you’ve taken the time to learn a bit about me and what I do. I hope to chat with you soon on an intro call or connect on social media! 

**a note about privilege… I want to acknowledge that as a thin, white, cis, able bodied woman, I live in a body that benefits from a lot of privilege. I do not personally understand someone’s lived experience of being in a larger body. I want to acknowledge the challenges that comes from being a larger bodied person in our society. I want to hear about what that experience has been like for you, if you live in a larger body. I’m fully equipped to guide you in this process regardless what your body looks like. I hope that in our work together you are able to find at least a bit more peace with your body, and learn to respect it just a bit more. I hope we can untangle weight from worth, value, and health so you can live a happier, more fulfilling life regardless of your body size. 

When I’m not serving my amazing clients, you can almost always find me outside. I LOVE the beach, hiking and connecting with nature. If i’m not outside, i’m likely reading the latest self-help book, trying new restaurants or spending the weekend cuddled up on the couch with my cat, Marshmallow.
