I am a Registered Dietitian with experience treating hormone imbalances, inflammation and gut/digestive issues that manifest in conditions such as PCOS, pre diabetes, insulin resistance, weight gain, bloating and IBS. Clients often come to me seeking not only the treatment for their symptoms, but to identify the root causes as to why they have those symptoms in the first place. I help my patients regain a sense of confidence in their body and eating patterns. I work with patients with goals to lose weight, improve their fertility/hormone balance, restore digestive health & regain a sense of energy as well as brain function & memory.

Are you chronically exhausted? Feeling anxious or on-edge? Struggling with heavy or painful periods? Dealing with digestive issues? Just not feeling like yourself? Life can be pretty stressful and when you aren't feeling your best, the last thing you want to do is worry about how or what to eat. Food truly is medicine and is meant to nourish our bodies and not something that we have to "earn" or overcomplicate. Life is meant to be lived to the fullest, so why let your symptoms hold you back any longer?

After encountering several health issues that lead to weight gain, constant bloating, depression, and infertility, I worked with multiple healthcare professionals to help myself get back on track. After years of ups and downs, I finally decided to take my health in my own hands and entered into a MS program to learn more about nutrition and functional medicine. It allowed me not only solve my health issues that no one could, but also to get pregnant after multiple years of unsuccessful attempts. Your daily nutrition is either a poison or a medicine, and I am excited to help you find an optimal balance between health and food!

How can a California Nutritionist help me?
Dietitians and Nutritionists in California provide advice on good eating habits. They help you with your diet and how it affects your health. They assess nutrition needs and food patterns, plan a diet that's appropriate for your physical and dietary needs, and provide nutrition counseling, such as advice on dietary changes and menu plans. They advise on special diets for medical conditions such as diabetes, high blood pressure, food allergies, and obesity.

The word dietitian has a variant spelling 'dietician' (e.g. find a California dietician). Both spellings are correct.

About California Registered Dietitians
Registered Dietitians or Registered Dietitian Nutritionists in California complete a bachelor's degree at a school accredited by the Commission on Accreditation for Dietetics Education of the Academy of Nutrition and Dietetics, as well as a period of supervised practice and an exam administered by the Commission on Dietetic Registration. While certification is not required in all states for nutritional counseling or nutrition therapy, only individuals certified by their respective states may use the Certified Dietitian or Certified Nutritionist titles.

How to use my insurance?
Some Nutritionists and California dietary professionals accept health insurance. Check to see if your insurance is covered. Feel free to discuss this when you contact the Nutritionist or Dietitian.
