Struggling with diabetes, weight, or digestive issues? I help clients uncover the root causes of symptoms—like inflammation, hormone imbalance, or gut dysfunction—and create personalized, sustainable plans that fit real life. With 16+ years as an RDN and CDCES, I guide you with evidence‑based, functional nutrition so you can lower A1C, improve digestion, boost energy, and feel confident in your health again.

Here’s a polished version under 360 characters: I provide culturally competent, one‑on‑one coaching with personalized nutrition and exercise plans to help clients lower A1C, manage weight, improve digestion, and reduce medication use. I specialize in diabetes, renal, and weight management, and also offer corporate and faith‑based wellness workshops.

Eating well is the foundation of a healthier, more fulfilling life. You don’t have to figure it out alone your challenges and goals truly matter. I’m here to support you with a personalized plan that fits your unique needs. When you’re ready, I’d love to walk with you on your journey to lasting wellness.
