I offer virtual visits through our medical platform Practice Better.
My philosophy centers on one simple, powerful truth: the gut is the foundation of health. You’re not alone if you feel trapped by symptoms yet routine labs were normal. Or you’ve been given medication, acid blockers, antidepressants or vague advice like “try eating better” without anyone asking why you have symptoms in the first place. I’ve been there too and I know a better way. My approach focuses on finding the root cause of your health concerns through deeper testing to answer key questions: What’s driving the inflammation? Is the gut lining compromised? Is the microbiome balanced? Is the body absorbing nutrients properly?

Are you a high-functioning woman 35+ whose digestion has gotten annoyingly unpredictable? Bloating shows up out of nowhere. IBS patterns shift. Hormonal changes make your “usual fixes” stop working. You’ve tried elimination diets and supplements that promised clarity and delivered... nothing. You want a structured, evidence-based plan to stabilize digestion, support hormone-related symptoms, and eat without constant second-guessing. I’ve lived with Crohn’s disease for more than three decades. That perspective informs a clinical approach focused on discernment and durable results, not generic advice or trend-driven protocols.

Medical Nutrition Therapy (MNT) Nutritionists and Dietitians
What is medical nutrition therapy?
Medical Nutrition Therapy (MNT) involves the use of personalized dietary changes to prevent or manage chronic conditions. Typically conducted in an outpatient setting by a Registered Dietitian (RD), MNT aims to address specific health issues through tailored nutrition plans. Clients are often referred for MNT by healthcare professionals who identify conditions that could benefit from dietary and lifestyle modifications, such as diabetes, hypertension, or cardiovascular disease. The goal of MNT is to improve overall health outcomes by making adjustments to the client's diet based on their individual needs and medical conditions.

What conditions is medical nutrition therapy for?
Medical Nutrition Therapy (MNT) is often used for individuals with diseases caused or worsened by poor diet, such as type 2 diabetes, hypertension, kidney disease, and cardiovascular diseases. However, other conditions can also benefit from nutrition therapy. MNT is typically not intended to replace other treatments, such as medication, but rather to complement them. By improving a person's overall diet and health, MNT aims to prevent the exacerbation of symptoms and complement other treatments.

Is medical nutrition therapy covered by insurance?
Medical nutrition therapy is frequently covered by insurance. However, insurance coverage can vary based on factors like your specific plan details, whether you choose an in-network or out-of-network provider, and whether you have a referral for nutrition services based on a medical diagnosis. While a referral is not required to see a dietitian or nutritionist, and many individuals independently seek nutritional support without prior medical advice, a referral from a primary care physician or another medical professional may be necessary to obtain coverage for medical nutrition services. In such cases, a referral is typically made for those who have been formally diagnosed with a medical condition requiring nutrition counseling, such as diabetes or hypertension. Coverage also depends on the type of nutrition service. Typically, insurance plans only cover services provided by a licensed Registered Dietitian (RD) and do not cover those offered by nutritionists or nutrition coaches without the RD credential. If nutrition services are not covered by your insurance, some dietitians and nutritionists may offer sliding scale rates or lower-cost services for clients who cannot afford their full fee.

What does medical nutrition therapy involve?
The approach a dietitian will take in a medical nutrition therapy session will depend on a number of factors, including what conditions the client has and what the goals of the client are. An initial session often involves an assessment of the client's overall health and current dietary intake; a dietitian may also speak with a client's medical doctor prior to or following a first session to obtain information on the medical condition(s) the client is seeking nutrition therapy counseling for. The dietitian will then work with the client to create goals of medical nutrition therapy sessions, such as weight loss, eating a more plant-based diet, or reducing sodium intake. Then, in ongoing sessions, the dietitian will work with the client to meet their stated goals. These ongoing sessions often include menu planning and coaching, which involve the dietitian working with the client to develop strategies for a healthier and more balanced diet. Dietitians may suggest recipes, put together grocery shopping lists, and/or recommend tracking one's intake in order to help clients make desired changes.
