Building nutrition and lifestyle habits is foundational, but I also use functional lab testing and targeted supplements to really dial in your plan.
Are you in your 40s, like me, and your hormones are taking you for a ride? Perhaps you continue to eat well and exercise but are experiencing weight gain, anxiety, night sweats, emotional eating, or other uncomfortable symptoms. You don't feel like yourself. Maybe your symptoms have been brushed aside by your doctor as "being a woman" or "getting older" without offering any effective solutions. I can help. I support women during times of hormonal change to get to the root of the issue and discover long-term health. Nutrition is a powerful tool for hormone balance through the fertile years, pregnancy, postpartum, and perimenopause.

My approach combines clinical nutrition, medical nutrition therapy, and functional medicine principles with behavior-focused coaching.
Do you feel like you’re doing everything right, but your weight, energy, digestion, or blood sugar still aren’t where they should be? Many people I work with are frustrated. They’ve tried diets, seen specialists, and tried to be healthy, yet their body doesn’t respond the way it once did. Often the issue isn’t willpower. Your metabolism may simply need the right support. Together we make small, simple changes to the food & lifestyle choices you make daily—guided by science, & tailored to your body. My clients report sustainable weight loss, steadier energy, improved digestion, blood sugar balance, strong bones, & renewed confidence.

As a Registered Dietitian and Functional Nutrition Practitioner with over 20 years of experience, I take a whole-person, root-cause approach to health.
Do you feel like something is off in your body, but you can’t get clear answers? Are you experiencing digestive symptoms such as bloating, gas, constipation, or diarrhea alongside fatigue, brain fog, weight changes, or thyroid concerns like Hashimoto’s? Have you been told your labs are “normal,” yet you still don’t feel like yourself? For many women, mid-life can bring overlapping symptoms that don’t fit neatly into one diagnosis. Digestive issues, hormone shifts, thyroid dysfunction, autoimmune conditions, and chronic stress are often deeply interconnected — and addressing just one piece rarely leads to lasting relief.

A nutrition plan doesn't mean you have to give up everything. (This seems to be the biggest fear when clients come in for an appointment.) Changing the way you eat can improve all kinds of health conditions, i.e.: asthma, an autoimmune condition, high cholesterol, fibromyalgia, fatty liver, non-alcoholic fatty liver, fertility issues, ADHD, low blood sugar, plantar fasciitis, pre-diabetes, diabetes, osteoarthritis, rheumatoid arthritis or other health issues. Don't wait for a health crisis in order to make a change in your nutrition. Receipts are provided for flex-spending reimburement. Medicare/other insurance not accepted.
