You may feel stuck in cycles of dieting, food rules, or disordered eating that leave you anxious, overwhelmed, or disconnected from your body. You’re tired of obsessing about what, when, or how much to eat, yet still feel bad no matter what you choose. Perhaps body image concerns, shame, or self-criticism make it hard to enjoy eating or to care for yourself. You want relief from confusion and stress around food and a way to nourish yourself without guilt. My clients are often searching for more freedom, ease, and trust with food—and a kinder, more sustainable relationship with themselves.

Hi, I'm Brenna! I work with adolescents, teens and adults who are struggling with disordered eating, recovery from chronic dieting, binge-restrict cycles, body image concerns and wanting to be able to pursue health without obsession. It's common to be interested in or passionate about food, health, wellness exercise - but when those interests become inflexible, or don't allow for you to spend time and feel present doing other things that are important to you, it can be a sign to reach out.

We eat at least 3-4 times a day or 21-28 times a week. Eating is an activity we have been engaging in since we were born. We used to know when we were hungry and when we were full. When this energy giving and life sustaining act becomes a source of confusion, guilt and fear, when eating becomes disordered and turns into a dangerous coping mechanism, it is time to evaluate what we are doing and explore how we can normalize our behavior so our minds and body can function in a healthy way to support our goals.

I specialize in Irritable Bowel Syndrome and complex gut issues that haven't responded to standard approaches.
My clients typically come to me with some combination of bloating, cramping, urgency, constipation, or diarrhea that hasn't resolved despite consistent effort, and confusion or fear around food after years of conflicting advice. Often, they've seen gastroenterologists and multiple providers without getting a clear answer.

Gastrointestinal (GI) Nutritionists and Dietitians
What is gut health?
Gut health refers to the overall functioning and well-being of the gastrointestinal (GI) system. Key to gut health is the gut microbiome, which is the collection of healthy bacteria living in the gut. These bacteria are essential for the digestion and breakdown of food, and their health significantly impacts digestion. Poor gut health can result in symptoms such as bloating, gas, diarrhea, constipation, and general abdominal discomfort, which may indicate imbalances or issues with the gut microbiome.

Can diet help with GI issues?
Diet plays a major role in gut health, and changes in diet can often reduce or eliminate some of the symptoms associated with gastrointestinal (GI) issues. Often, GI distress is due to food intolerances or sensitivities, such as gluten sensitivity or lactose intolerance. In these cases, eliminating the problematic foods from the diet can resolve the issue. GI problems can also stem from a combination of environmental or genetic factors, such as in the case of irritable bowel syndrome (IBS). Disruptions in the gut microbiome, such as those caused by taking antibiotics, can also lead to GI issues. In both scenarios, maintaining a balanced diet as much as possible with foods that support a healthy microbiome—such as fruits, vegetables, whole grains, and probiotic foods—can often significantly reduce symptoms and improve gut health.

What are the best foods for gut health?
Maintaining a balanced microbiome is essential for gut health, and this is best achieved through a varied diet rich in fruits, vegetables, and probiotic foods. Fruits and vegetables provide essential nutrients and fiber, which nourish the beneficial bacteria in the gut. Probiotic foods, which are those that contain live bacteria, are also great for gut health. Consuming probiotic foods and drinks, such as yogurt, kefir, kombucha, and tempeh, can help support the microbiome by contributing to the diversity of bacteria within the gut.

When should I see a dietitian for GI issues?
Many people can benefit from seeing a dietitian for GI issues. In general, most dietitians are knowledgeable about what foods support gut health and may help clients choose foods that support a healthy GI system, such as fruits and vegetables high in fiber or foods high in probiotics. Dietitians may be especially beneficial to clients with known gastrointestinal concerns, such as irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD). For clients diagnosed with these or similar conditions, dietitians can help clients identify food triggers and develop a meal plan for the client that minimizes symptoms. Dietitians may also work with clients who are having gastrointestinal distress (such as bloating, gas, constipation, diarrhea, etc.) but are not aware of the cause of their symptoms. In such cases, dietitians may be able to help the client identify the cause of the GI distress and coordinate with other medical professionals to help the client better manage their symptoms.
