I take a multifaceted approach, and help women uncover & address the root causes of their symptoms through functional lab testing, nutrition, and practical lifestyle strategies.
You’ve been chasing symptoms for years, but nothing ever seems to stick. Your energy is tanked. And you are SO over the brain fog, bloating, headaches, and periods that leave you wiped out—whether they’re painful, heavy, or completely unpredictable. You want answers, and a way to actually feel like yourself again without another bandaid solution or fad diet. I help women like you slow down, tune into their bodies, and learn how to deeply nourish themselves so their energy, digestion, and hormones can come back into balance. Vibrant health is your birthright, and your body is capable of so much more than you’ve been told.

My ideal client is a woman with PCOS who feels overwhelmed, unheard, or frustrated by conflicting advice.

I utilize an integrative approach which combines the use of both functional and conventional approaches to create a unique, personalized care plan.
Are you experiencing digestive issues, hormone imbalances, or disordered eating? Do you feel stuck and unsure of what step to take to reach your health goals? With so much noise surrounding diet and health, it can feel stressful and overwhelming to discern what to eat. I get it.

I practice integrative, functional nutrition focused on identifying root causes.
Are you a high-functioning woman 35+ whose digestion has gotten annoyingly unpredictable? Bloating shows up out of nowhere. IBS patterns shift. Hormonal changes make your “usual fixes” stop working. You’ve tried elimination diets and supplements that promised clarity and delivered... nothing. You want a structured, evidence-based plan to stabilize digestion, support hormone-related symptoms, and eat without constant second-guessing. I’ve lived with Crohn’s disease for more than three decades. That perspective informs a clinical approach focused on discernment and durable results, not generic advice or trend-driven protocols.
