At The Rite Bite Nutrition Counseling, our team of award winning Registered Dietitian Nutritionists takes a different approach. We don’t do fad diets or one-size-fits-all plans. Instead, we offer evidence-based, personalized care that works with your lifestyle and goals.

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 ideal client is someone who has tried to lose weight many times but feels overwhelmed, discouraged, or confused about what to eat—especially if they are using GLP-1 medications and want to make sure they’re doing it “right.” They may be struggling with low appetite, nausea, inconsistent eating patterns, muscle loss concerns, or frustration with slow or unpredictable progress. Many feel like their bodies have changed faster than their habits, and they’re not sure how to fuel themselves in a healthy, balanced way. They want guidance —not strict rules, judgment, or complicated plans.
