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.

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?

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.
