Who I help
Nutrition care for your health—not another diet.
Nutrition can play an important role in managing chronic conditions, supporting treatment, and improving long-term health. Your care should be based on your health, your goals, and the realities of your life—not a one-size-fits-all diet.
Nutrition care grounded in physiology, medical nutrition therapy, and current clinical guidelines.
I work with individuals navigating:
Cardiovascular disease and heart health management
Type 1 and Type 2 diabetes
Cancer treatment and recovery
Pregnancy and postpartum
Weight Management and GLP-1 Support
My approach:
Evidence-based and clinically informed
Tailored to diagnosis, labs, and treatment plans
Focused on real-world application, not restrictive diets
Aligned with interdisciplinary medical care
Care is designed to support— not replace— your medical team.
