I specialize in helping women with IBS, bloating, reflux, and constipation using personalized nutrition, gut-healing strategies, and optional testing.
I help women who are frustrated, exhausted, and constantly wondering what foods will set her off. She’s been dismissed or overwhelmed by rigid plans that don’t address the root of her symptoms. She just wants to feel normal again - less bloating, more energy, consistent digestion, and peace around food. She wants a plan that works in real life and a provider who listens. She’s ready to stop guessing, feel confident in her body, and finally enjoy food and life again.

My ideal clients are adults who want to improve their health by addressing the root cause of their symptoms, not just managing them temporarily. They often come to me feeling frustrated because they still struggle with fatigue, bloating, digestive issues, hormone imbalances, weight changes, inflammation, stress, or chronic conditions even when their labs look “normal.” Many also seek support for weight management, fertility, gut health, metabolic balance, or GLP-1 medication support. My team helps them move forward through personalized nutrition counseling, practical strategies, education, and sustainable lifestyle changes.

Individuals using GLP-1 medications (Ozempic, Wegovy Mounjaro) or transitioning off them who feel overwhelmed by hunger changes, food noise, or fear of weight regain. Many have tried dieting or received limited guidance beyond medication. They are often referred by physicians or seeking a structured, evidence-based approach. I help them understand what is happening physiologically and follow a clear process to stabilize, reduce anxiety around food, and move forward with confidence.

If you've been struggling to lose weight and improve your health despite trying traditional dieting methods, you're not alone. You’ve probably tried restricting calories or exercising more, only to find yourself stuck and unable to achieve lasting results. Chances are, you're dealing with underlying imbalances—like hormonal fluctuations, metabolic issues, or stress-related factors—that are contributing to weight gain and poor health. It’s frustrating when diets and workouts don’t seem to work, leaving you feeling confused and discouraged, as if your body is working against you.

Irritable Bowel Syndrome (IBS) Nutritionists and Dietitians
What is Irritable Bowel Syndrome (IBS)?
Irritable bowel syndrome (IBS) is a general term that refers to a collection of symptoms associated with poor gut mobility and function, including abdominal pain, bloating, gas, and diarrhea. IBS is very common, with some estimates suggesting that as many as 10-15% of adults within the United States have IBS. Although the two conditions sound similar and share many symptoms, such as abdominal pain and diarrhea, IBS differs from irritable bowel diseases (IBDs), such as ulcerative colitis and Crohn's disease. In contrast to IBS which is caused by issues in the functioning of the colon, IBDs are inflammatory conditions caused by overactive immune cells within the intestine. IBDs are much less common than IBS and typically more medically severe, occasionally requiring intensive medical treatment and/or surgery. IBS, in contrast, can usually be managed effectively with lifestyle changes and less intense medical intervention.

What are the subcategories of IBS?
Medical professionals generally identify four main types of IBS: IBS-C (constipation-predominant subtype), IBS-D (diarrhea-predominant subtype), IBS-M (mixed bowel subtype), and IBS-U (undefined subtype). Identifying the predominant type of IBS an individual has can be important for determining the type of treatment that is best for them, such as the lifestyle and dietary changes that may be most appropriate, as well as any medications that may be necessary. However, individuals may also experience multiple subtypes over time, as well as experience cycles of flare-ups and symptom relief.

What causes IBS?
The causes of IBS are not well understood, but symptoms are generally attributed to issues with gut muscle contraction and changes in the gut microbiome, both of which can lead to the characteristic symptoms of IBS. These issues can be caused by a variety of lifestyle factors, such as diet and stress. While lifestyle modifications may not completely cure IBS symptoms, identifying symptom-triggering foods, consuming a balanced diet, and reducing stress have all been shown to greatly reduce symptoms. IBS can also be caused by bacterial or parasitic infections within the intestine, in which case the syndrome is referred to as "post-infectious IBS." In contrast to non-infectious IBS, post-infectious IBS is less chronic in nature and symptoms will often resolve once the infection has subsided.

What foods should I avoid if I have IBS?
Specific foods that may trigger symptoms of IBS can vary person-to-person. However, common foods that may exacerbate symptoms include high-fat foods (such as fatty meats), wheat, dairy products, highly acidic foods (such as citrus), beans, cabbage, milk, and carbonated drinks. Over time, individuals with IBS are often able to identify which foods cause their symptoms to worsen and learn to avoid such foods to manage their symptoms.
