As a Board-Certified Nutrition Specialist (CNS) I use a functional medicine approach to help you develop sustainable diet and lifestyle changes so you can feel your best.
I work with adults looking for sustainable weight management, metabolic health support, and ADHD-friendly nutrition care. Whether your goals include improving labs, managing type 2 diabetes or prediabetes, addressing fatty liver, or creating structure around food and self-care, we focus on progress that feels doable and supportive, not overwhelming.

My approach blends functional and practical care to restore digestive balance and confidence.
I help women who are frustrated, exhausted, and constantly wondering what foods will set her off. She’s been dismissed or overwhelmed by rigid plans that don’t address the root of her symptoms. She just wants to feel normal again - less bloating, more energy, consistent digestion, and peace around food. She wants a plan that works in real life and a provider who listens. She’s ready to stop guessing, feel confident in her body, and finally enjoy food and life again.
