I work with patients navigating the complex world of cardiometabolic conditions, PCOS, and chronic health challenges who feel overwhelmed by conflicting advice and failed quick fixes. They're seeking more than temporary solutions—they want sustainable, science-based approaches that honor their unique circumstances and busy lives. These are people ready to dig deeper, understanding that true health transformation requires addressing root causes rather than just managing symptoms. They value expertise but also need genuine understanding of how difficult it can be to change lifelong patterns while juggling work, family, and

Do you feel confused and overwhelmed by what to eat? Have you been feeling "off" for so long you can't remember what normal feels like? Are you struggling with gas, bloating, diarrhea, heartburn, and/or constipation? I provide supportive nutrition counseling for gut problems. I help adults and children who struggle with digestive issues, such as Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), Small Intestinal Overgrowth (SIBO), Candida overgrowth, Gastroesophageal Reflux Disease (GERD), Celiac Disease, and food allergies. We will get to the root of the problem so you can eat with freedom and comfort.

Whether you’re recovering from an eating disorder or working toward a more peaceful relationship with food, I emphasize a flexible, weight-neutral approach to nutrition. This means moving away from labeling foods as “good" or "bad” and letting go of seeing your body as something to fight against. I invite you to reconnect with your body as a vehicle for living and experiencing the world, rather than something to control. My goal is to support choices that feel informed and aligned with your needs, not driven by rules. If you’re looking for a supportive, judgment-free space where you can show up as you are, we might be a good fit.
