I specialize in Irritable Bowel Syndrome and complex gut issues that haven't responded to standard approaches.
My clients typically come to me with some combination of bloating, cramping, urgency, constipation, or diarrhea that hasn't resolved despite consistent effort, and confusion or fear around food after years of conflicting advice. Often, they've seen gastroenterologists and multiple providers without getting a clear answer.

Whether you are looking for guidance on Autoimmunity, Sports Performance, Fertility, GI Dysfunctions, Anxiety/Depression or just want more energy and better sleep, I'm here to partner with you.
As a functional nutrition and health coach, I know that you are unique and one solution (or pill!) does not fit all. After childhood allergies/asthma, frequent infections and fatigue, I was diagnosed with reproductive cancer and an autoimmune disease. I've been through it all, so I understand how frustrated you feel when your body stops working. Together, we'll build a strong foundation for you from the ground up with food, lifestyle and mindset enhancements. My programs improve sleep, energy, mental focus, and build better lifelong habits so you can accomplish more every day.

I also specialize in relieving the symptoms associated with GI conditions such as IBS and IBD.
My ideal client is someone who is looking to improve their overall health and well-being with sustainable and realistic changes to their eating patterns. Most of my clients are surprised to discover that the dieting behaviors they have participated in (e.g. restricting calories/macros or avoiding food groups) are actually more harmful to their health than health promoting. I teach my clients how to eat in a way that works best for their individual needs and preferences, remove the guilt associated with eating certain foods, and help them feel confident in their food choices.
