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 help clients overcome common obstacles to weight loss, fix their relationship with food, and break up with dieting for good. Are you "doing the right things" to lose weight, but it's just not working? It's not you OR your lack of willpower. Traditional diet advice may work in the *very* short term, but ultimately works against your physiology leading to a sluggish metabolism and (unfortunately) weight gain. Luckily, it is possible to reverse this, then work with your body to reduce inflammation and balance your hormones, to make weight loss both achievable AND sustainable.
