I emphasize Food As Medicine and utilize functional medicine to identify food triggers or intolerances, metabolic or hormonal imbalances, and nutrient deficiencies, while also addressing behavioral aspects of diet and lifestyle to help improve health and wellbeing.
Our lives revolve around and depend on food, which is why nurturing your relationship to food is crucial to your health and something I strive to help strengthen. My approach to nutrition therapy is collaborative and personalized to optimize function within the whole body. Evidence-based nutrition science, health coaching, and trauma-informed care guide my practice to meet the needs of each individual I work with. I recognize the various challenges that can impact proper nutrition and aim to reduce internal and external limitations through nutrition education, empowerment, and behavior change.

My approach combines clinical nutrition, medical nutrition therapy, and functional medicine principles with behavior-focused coaching.
Do you feel like you’re doing everything right, but your weight, energy, digestion, or blood sugar still aren’t where they should be? Many people I work with are frustrated. They’ve tried diets, seen specialists, and tried to be healthy, yet their body doesn’t respond the way it once did. Often the issue isn’t willpower. Your metabolism may simply need the right support. Together we make small, simple changes to the food & lifestyle choices you make daily—guided by science, & tailored to your body. My clients report sustainable weight loss, steadier energy, improved digestion, blood sugar balance, strong bones, & renewed confidence.

As a Registered Dietitian with a Master's in Nutrition & Functional Medicine, I look beyond food choices to assess digestion, nutrient status, and the microbiome.
My clients typically come to me with some combination of bloating, cramping, urgency, constipation, or diarrhea that hasn't resolved despite consistent effort, and confusion or fear around food after years of conflicting advice. Often, they've seen gastroenterologists and multiple providers without getting a clear answer.

As a Registered Dietitian and Functional Nutrition Practitioner with over 20 years of experience, I take a whole-person, root-cause approach to health.
Do you feel like something is off in your body, but you can’t get clear answers? Are you experiencing digestive symptoms such as bloating, gas, constipation, or diarrhea alongside fatigue, brain fog, weight changes, or thyroid concerns like Hashimoto’s? Have you been told your labs are “normal,” yet you still don’t feel like yourself?
For many women, mid-life can bring overlapping symptoms that don’t fit neatly into one diagnosis. Digestive issues, hormone shifts, thyroid dysfunction, autoimmune conditions, and chronic stress are often deeply interconnected — and addressing just one piece rarely leads to lasting relief.
