I am a Massachusetts Chinese Medicine doc and Licensed Dietitian. I studied Functional Medicine before it became a buzzword 15+ years ago, although no longer use expen$ive testing but focus on Chinese Medicine diagnosis and treatment. I have a special interest in the areas of digestive issues such as bloating, gas, diarrhea, IBD, IBS, and reflux but see SIBO as a symptom rather than a cause. I do not give out SIBO diets, but work on fixing the underlying issue. If you have GYN issues such as heavy bleeding, menopausal symptoms, or pain during periods I can almost certainly help you with Chinese Medicine.

A PCOS diagnosis can be scary and confusing. You've been handed a medication without any education on the connection between nutrition & PCOS. You're told to "just lose weight" to improve your symptoms, yet you've tried every diet in the book. You're lost on what is actually happening in your body. And, you are craving guidance!

My ideal client can be of any age or background. They may be seeking weight loss, better performance, improved labs, muscle gain, or a healthier relationship with food. What matters most is that they’re open to problem-solving—willing to examine habits with curiosity, apply evidence practically, and use accountability to measure progress. They understand that change requires consistency, reflection, and course correction; if they’re not fully ready, they’re willing to explore what’s in the way.

My ideal client is someone who’s ready for real change but feels stuck. Maybe they’ve tried diets, medications, or programs before, but nothing has worked long-term. They may be struggling with weight, newly diagnosed with type 2 diabetes or prediabetes, or managing chronic issues like high cholesterol or high blood pressure. Many are overwhelmed by conflicting nutrition advice and just want to know what to eat — and how to stick with it. What they really need is a plan that makes sense for their life — not a generic handout or fad diet. They want support from someone who listens, simplifies the process, and keeps them accountable.

Postpartum Nutrition Nutritionists and Dietitians
What is postpartum nutrition?
Postpartum nutrition refers to the dietary practices and consumption of specific foods during the postpartum period, when the mother is recovering from childbirth and breastfeeding. Proper nutrition during this time is essential and can help replenish nutrients lost during childbirth, aid in healing, and ensure an adequate milk supply for the baby. Nutrition professionals specializing in postpartum nutrition can provide personalized consultation, helping new mothers identify the best foods for recovery and breastfeeding. They can also offer practical advice on adjusting eating habits to fit into the new routine of caring for a newborn.

Why is nutrition important during the postpartum period?
A healthy and balanced diet during the postpartum period is essential for both recovery from childbirth and supporting breastfeeding. Consuming a variety of nutrient-rich foods, such as whole grains, lean proteins, fruits, vegetables, and healthy fats, is crucial during this time. Additionally, breastfeeding women burn an extra 300-500 calories per day on average, so it’s important for them to consume enough calories to meet this increased demand. Key nutrients such as iodine, choline, and iron are particularly important during the postpartum period, as they play vital roles in maternal health and infant development. To ensure all nutrient requirements are met, doctors may recommend dietary supplements to help women get enough essential nutrients during the postpartum period.

What foods should I avoid postpartum?
Nutrition experts generally advise women to avoid alcohol, caffeine, and high-sugar foods during the postpartum period. It's also recommended that postpartum mothers avoid foods that may contain high levels of harmful chemicals, such as certain fish like mackerel, swordfish, and tuna, which can contain high mercury levels that may negatively affect a newborn's development if passed through breastmilk. Additionally, foods with strong smells and flavors, such as garlic, are often discouraged as they may cause the baby to reject breastfeeding due to taste preferences.

What diet is best for breastfeeding mothers?
For breastfeeding mothers, a well-rounded and nutritious diet is essential to support both the mother's health and the baby's growth and development. In general, it is recommended that breastfeeding mother's focus on consuming a balanced diet that contains whole grains, vegetables, fruits, healthy fats, and lean protein sources. In particular, ensuring that one is getting enough protein can be critical to ensuring sufficient breast milk supply. Sources of such protein include dairy products, lean meats, eggs, nuts and seeds, and beans. Additionally, certain fish that are low in mercury, like salmon, bluefish, and bass, are particularly beneficial, as they provide omega-3 fatty acids, including docosahexaenoic acid (DHA), which supports healthy infant brain development.
