Why Holistic Nutrition?

Holistic nutrition is more than just food and restrictive diets - it's about restoring your health on a cellular level, using whole foods, herbs, supplements and wellness therapies, based on your individual biochemistry, to improve your health. You are what you eat, absorb, assimilate and eliminate. This dynamic relationship of the body's system is unique to each person and why it is important to understand exactly what's going on in your body regarding your health.  Holistic nutrition gives you the natural tools to build better health by understanding why you got here, and empowering you with the knowledge to achieve your health goals naturally.


"Taking probiotics in the mornings got my bowels moving and helped my digestion.  Also learned not to take my supplements at the same time as my medications."

Colorful Food

As your holistic nutritionist, I provide comprehensive services to guide and educate you on the tools you need to overcome your digestive imbalances, such as IBS, Crohn's, gastritis, celiac, ulcers and other gastro inflammation.   Research shows that 70% of your immune system is in the gut - so taking care of it is KEY to good overall health.  Since 2010, I’ve worked with clients in order to achieve optimal health by focusing on improving gut health with simple nutrition and lifestyle solutions.    Get in touch to learn more and take a big step in your health and wellbeing.


As someone who also struggled with sleep once upon a time, I understand the weight and frustration of needing help but not knowing where to turn to first. That’s why my mission is simple: give my clients the wellness education, tools and resources that they need to identify the cause of their sleep problems, understand the processes to fix them, and put a plan together that’s personalized and effective.


I know that life can seem like a repetitive cycle of waking up, eating, working and sleeping. And that the daily grind can fill our minds and bodies with negative energy and stress.   The outcome? Not feeling good, health imbalances and potentially dis-ease. That’s why my mission is simple: give my clients the wellness education, tools and resources that they need to feel happy, healthy, and capable of managing life’s pressures. Get in touch to get started!

Hormone Health

Hormones are just as complicated as relationships.  You're not in this alone.  Whether its acne, PMS, infertility,  decreased libido, pregnancy or menopause, I’ve been helping my clients find their optimal wellness by balancing hormones and understanding their habits and lifestyle choices. My extensive experience means that I'm fully equipped to guide, support and assist you in helping you to accomplish your health goals.  As a Registered Holistic Nutritionist, I aim to create a nutrition and wellness plan that prioritizes your well-being and celebrates all aspects of your true self. It’s time to start nurturing your body and soul again!

Mental Health

Mental health is the gateway to good health, and equally as important as gut health. In fact, the two are connected through the Vagus nerve.  So what you eat affects how you think, and how you think, affects what you choose to eat.  Being a holistic nutritionist over the past 10 years has taught me that every moment filled with doubt, anxiety or pressure can be used as a catalyst for a fresh start. Your road to optimal health begins here.


Research shows that the average human carries between 7 - 28lbs of accumulated waste and toxins in the gut.  Just like your car needs an oil change every few months, your gut also needs a cleansing to help YOU perform better.  I provide a custom detox plans, based on your unique health, and work closely  with you in order to achieve your goals.
