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.

Medical diagnoses are freightenting. Often, I have found my clients receive little education on ways to manage clinical conditions, such as chronic kidney disease and diabetes. With limited guidance, their condition progresses and can result in profound impacts on physical and mental health, and quality of life.

No, you don't need drugs to improve your blood sugar, lose weight, or deal with PCOS. Yes, medications might seem convenient; however, this road goes nowhere. With time, your drug quantity will increase because these drugs can’t treat the causes of your problems. Based on the latest research, effective treatment of diabetes and PCOS can be achieved by working with gut microbiome. I use gut microbiome in my practice not only to lower insulin resistance and lower blood glucose but also for weight loss, getting regular periods, and improving the ability to conceive for girls with PCOS.
