Fun Things About Me

☕ Most mornings, you’ll find me curled up with a coffee, already daydreaming about lunch before I’ve even had breakfast.
🎧 I love long walks paired with a good mystery podcast.
🍪 I believe in nourishing both body and soul—cookies are just as welcome as protein bowls in my kitchen.
🌎 I’m based in Massachusetts and work with clients virtually across the U.S.

GLP-1 medications can support weight loss, but nutrition still matters.

I help clients avoid under-fueling, protect muscle, manage side effects, and use medication in a way that supports steady, sustainable progress — not extremes.

GLP-1 Nutrition
Sustainable Weight Management

Sustainable weight change isn’t about constant hunger or rigid rules.

I help clients focus on fueling well, protecting muscle, and making small changes that add up over time. Progress comes from consistency and nourishment — not extremes or quick fixes.

Physical Therapy
Fueling & Recovery

Weight loss and injury recovery often overlap, and nutrition can feel confusing when movement is limited.

I help clients fuel for healing, preserve muscle, and navigate weight concerns without compromising recovery.

About Me

I’ve always loved food — cooking it, sharing it, and enjoying it. But like many of the people I work with, I also know firsthand how confusing and frustrating weight loss can feel.
Before becoming a dietitian, I tried the fad diets, juice cleanses, and 1,200-calorie days in college. None of them worked long-term, and the rebound often felt worse than where I started. Eventually, studying nutrition helped me see my body as something to support, not fix. I began to focus on nourishing my body in a way that felt sustainable — and yes, I still check the dessert menu first. That shift changed how I live and how I work.

How I Got Here

Early in my career, I worked as a Physical Therapy Aide, helping patients rebuild strength after injury. I saw firsthand how much nutrition impacts healing, energy, and progress — and how often people felt overwhelmed or under-fueled in the process. That experience stayed with me and eventually led me to become a Registered Dietitian.

Being both a clinician and someone who’s walked the ups and downs of weight loss helps me blend evidence-based guidance with real-world practicality. I want nutrition to fit your life — not make it harder.

My Approach

I help people lose weight sustainably, preserve muscle, and support recovery — without extremes, shame, or false promises. My work is grounded in clinical nutrition science, not trends or guesswork. That means we focus on what actually works for your body, your goals, and your life.

Here’s what that looks like in practice:

  • Realistic, nutrient-dense eating that fuels your body

  • Small, sustainable changes, not drastic overhauls

  • Protein-focused strategies that support strength and energy

  • Nutrition that fits real life, even on low-appetite or limited-movement days

  • Calm, judgment-free guidance you can rely on

Food shouldn’t make life more complicated — it should make it fuller.

If you want steady energy and confidence with food, I’d love to help.
