What Is Medical Nutrition Therapy?
Medical Nutrition Therapy (MNT) is an evidence-based approach that uses individualized nutrition assessment and counseling to manage and prevent chronic conditions such as diabetes, cardiovascular disease, kidney disease, and obesity. At District Endocrine, Rosalie Tierney, RDN, LD, CDCES — a Registered Dietitian Nutritionist and Certified Diabetes Care and Education Specialist with over seven years of clinical experience — provides personalized nutrition and diabetes education services at all three of our Northern Virginia locations.
Rosalie's approach is compassionate, collaborative, and focused on creating practical nutrition strategies that fit into everyday life. Whether you are newly diagnosed with diabetes, managing a chronic condition, or looking to build sustainable healthy habits, Rosalie works alongside our endocrinology team to support your long-term health goals.
Diabetes Prevention & Management
Rosalie provides individualized diabetes nutrition counseling for patients across the full spectrum of diabetes care. Working closely with our endocrinologists, she helps patients understand how food, activity, and medication interact — and builds practical meal strategies tailored to each patient's lifestyle, preferences, and medical goals.
Additional Clinical Areas
In addition to diabetes care, Rosalie provides nutrition counseling across a range of conditions commonly seen in endocrinology practice:
- ✔Cardiovascular Health — Hypertension, hyperlipidemia, and heart-healthy nutrition counseling to reduce cardiovascular risk
- ✔Women's Health — PMOS (PCOS), pregnancy nutrition, and menopause-related nutrition concerns
- ✔Renal Health — Chronic kidney disease nutrition therapy and kidney stone prevention
- ✔Weight Management — Sustainable lifestyle changes, behavior modification, and medical nutrition therapy for long-term weight management
What to Expect at Your Appointment
Your first visit with Rosalie includes a comprehensive nutrition assessment covering your medical history, current eating habits, lifestyle, and personal health goals. Together, you will develop an individualized nutrition care plan with practical, achievable steps. Follow-up visits track progress, address barriers, and adjust strategies as your health evolves.
