Tired of bloating, fatigue, or unexplained weight changes that don’t make sense no matter what you eat? I help people frustrated by food sensitivities, IBS, and stubborn metabolism issues uncover the root causes driving their symptoms. My functional-nutrition approach helps you calm inflammation, balance digestion and hormones, and rebuild trust in your body so energy, clarity, and a healthy weight become natural outcomes — not obsessions.

I take a functional and root-cause approach to bring your health back into balance. This holistic approach includes looking at all aspects of you and your lifestyle, including health history, current state of health, diet, sleep patterns, response to stress, work, family , and recreational aspects of your lifestyle. In addition my approach is to get to the underlying cause of the symptoms or conditions rather than just treat the symptoms.

I specialize in Irritable Bowel Syndrome and complex gut issues that haven't responded to standard approaches. I work with people who are still struggling after trying low-FODMAP or elimination diets and who want to understand why their body isn't responding to move beyond restrictive diets and feel better. 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. This is how we find the root cause and build a plan for healing.

Ideal clients are individuals who spend a significant amount of time worrying about their body, weight, and food choices, often feeling trapped in a cycle of restriction, guilt, and frustration. They may believe they'll never achieve their health goals. These clients are ready to explore the diet cycle, challenge misinformation, and develop mindfulness around their thoughts on food, weight, and health. This process helps quiet the constant “food noise” in their minds and fosters greater self-compassion, freedom, and peace with food.

Emotional eating is a condition that is widely misunderstood. All too often, it is assumed that emotional eaters have no willpower over food or lack the motivation for change. Feelings of guilt, shame, and even loneliness can create a perpetual cycle of dieting and deprivation followed by uncontrolled eating. If this feels familiar to you, I want you to know that you are not alone. I can help you understand this cycle to develop a better relationship with food. I provide education to clear up conflicting nutrition facts, challenge diet myths, and work with you to discover a pattern of eating that supports your health.

Nutrition Counseling Nutritionists and Dietitians
What is nutrition counseling?
Nutrition counseling refers to the services provided by a Registered Dietitian (RD) that focus on diet and nutrition. Individuals often seek nutrition counseling to make diet-related lifestyle changes, especially after being diagnosed with chronic conditions such as hypertension, diabetes, or cardiovascular disease. However, nutrition counseling is not limited to these cases, and it can often benefit anyone looking to improve their overall health. Nutrition counselors also often address other aspects of a healthy lifestyle within sessions, such as advising on physical activity, chronic disease management, and mental health. They provide guidance and motivation, often adopting a holistic approach to support clients in achieving their health and wellbeing goals.

Who should see a nutrition counselor?
Many people can benefit from seeing a nutrition counselor; however, individuals with (or at risk of developing) chronic medical conditions or who have specific dietary challenges (for example, IBS, Crohn's disease, etc.) may find a nutrition counselor particularly helpful. Nutrition counselors are specifically trained to use diet modifications to manage health, so consulting a dietitian if you have a chronic condition can be greatly beneficial. Nutrition professionals can help clients understand how their diet impacts their symptoms and suggest strategies to improve overall health. Additionally, dietitians can coordinate with other medical professionals, such as primary care physicians or specialty physicians, to help support the client's overall health.

What happens during a nutrition counseling session?
Nutrition counseling is fundamentally focused on a client's individual health goals. The initial session with a nutrition professional typically involves an evaluation, during which the dietitian seeks to understand the client's reasons for seeking nutrition counseling. This session typically includes discussing the client's health history, current eating habits, lifestyle, and specific nutrition counseling goals. In follow-up sessions, the client and dietitian will typically review progress toward these goals, and the dietitian may examine the client's food intake and suggest areas for improvement. They may also educate the client on diet-related topics, such as ensuring adequate consumption of fruits and vegetables or reducing sodium intake. Additionally, nutrition counselors can help clients stay accountable for other lifestyle changes that support overall health, such as regular exercise, smoking cessation, or moderating alcohol consumption.

What should I look for in a nutrition counselor?
Clients seek nutritional support from dietitians and nutritionists for various reasons, ranging from managing medical conditions to addressing lifestyle concerns like weight loss or specific dietary requirements. When looking for a nutrition counselor, it is essential to find someone with expertise in the area of nutrition relevant to your needs. Consider factors such as insurance coverage, specific medical or dietary concerns, and the availability of professionals in your area to determine the best fit. Generally, nutritionists are not covered by insurance, whereas Registered Dietitians (RDs) often are, making it important to look for a professional with RD credentials. If you have a chronic medical condition like cancer or kidney disease, you may be interested in seeking out an RD with specialized expertise, such as a Board Certified Specialist in Oncology Nutrition (CSO) or a Board Certified Specialist in Renal Nutrition (CSR), as these credentials indicate advanced education and a commitment to ongoing learning within a specific area.
