Who I AM

Your guide to a better, healthier YOU!

Are you frustrated with “normal” labs that say everything looks fine, yet you still don’t feel your best? It’s time for a different approach. I use advanced functional labs and personalized metabolic programs to uncover the root causes behind fatigue, rising cholesterol, stubborn weight challenges, and creeping blood sugar or A1C. Sessions are in-person or virtual, so you can get support wherever you are. My goals are to help you shift your metabolism, restore your energy, and feel like yourself again.

What I OFFER

Get to the root cause.

Functional nutrition goes beyond traditional approaches to health. By using the principles of functional medicine, I take a deeper dive into your metabolism blocks, like hormones, gut health, detoxification, and lifestyle, to uncover why you don’t feel your best. When we address the root cause, real transformation happens! 

Lab-analysis

Functional Lab Testing

Go beyond routine labs to reveal what's really happening in your body, from metabolism and nutrient status, to gut health, hormones, genetics, toxins, and food sensitivities. These insights help to create an effective personalized plan.

Testimonials

A few kind words

Kathleen A., RN, BSN Registered Nurse

Ana's education in functional nutrition and supplements was the key to resolving my struggle with long-term inflammation. Ana is incredibly knowledgeable about clean eating, which allowed my body to heal. Her knowledge in natural supplements helped my liver, kidney, and vascular system to function better.

Holly H. Creative Director

I had a rib injury several months ago that was keeping me down with a significant amount of pain. I avoid prescription pain pills at all costs if possible. Ana turned me on to one of her nutritional supplement products that turned out to be an absolute game changer. Forever grateful -- thank you Ana!

I’ve been working with Anna for years, and her nutritional guidance has been one of the most valuable investments in my health—especially now at 51, as I navigate the challenges of perimenopause. From the beginning, Anna took a holistic and personalized approach. She carefully considered my age, hormone shifts, lifestyle, and health concerns, including my rising cholesterol levels and fear of losing muscle mass.

Thanks to her support and expertise, I’ve not only stabilized my cholesterol but have also maintained lean muscle and slowed the upward trend in my BMI—all without feeling deprived or overwhelmed. Anna’s approach is realistic, science-based, and deeply encouraging. I’m absolutely thrilled with my results and couldn’t have done this without her thoughtful and empowering guidance.

You will not find a more passionate and informed nutritionist. I’m down 20 lbs of body weight, while adding 15 lbs of muscle. All while never feeling hungry or deprived. I could never have done this alone. Thanks, Ana.

I started Accutane and was concerned about the potential liver issues and high triglycerides. My triglyceride #'s were high due the meds. Her recommendations really helped with the process so that I could continue with Accutane and help my body.

Ana is awesome! She really helped me learn about nutrition and how it affects my body. Between her meal plans and supplements, I'm healthier and feel better! She's always very responsive and there to answer my questions. She even offered to come to my house to help me prepare a healthy meal (I really don't know how to cook.) She wants you to succeed and is personally invested in seeing that happen.

At 52 years old I started having health issues and just attributed it to stress and aging. I consulted with Ana and she recommended a cortisol test and vitamins/minerals test for deficiencies. I did that and had pages of information. Then we were able to have a personalized plan which helped me have more energy and feel better.

Ana has helped me improve my health, specifically, improve my metabolic health. My doctor told me I had high cholesterol and needed to go on medication. Ana educated me on cholesterol type and we did a test to look at the size and density of my cholesterol. Then she gave me a plan to lower my risk naturally. Thanks to her I don’t need medication anymore.

According to the Institute for Functional Medicine, “Functional medicine determines how and why illness occurs and restores health by addressing the root causes of disease for each individual.” Functional nutrition applies these same principles through food, lifestyle, and targeted interventions. It looks at how nutrition, stress, sleep, environment, and mindset all influence health and healing.
