If you're dealing with low energy, brain fog, blood sugar swings, stubborn weight, or lab results your doctor wants you to keep an eye on, you deserve support that fits your real life.

I'm Sharon, a Certified Nutrition Specialist offering virtual nutrition counseling for cardiometabolic health, hormone health, and ADHD- and neurodivergent-friendly eating strategies. I'm licensed in Oregon, Maryland, Illinois, and Washington and work with clients in many other states. We'll look at the whole picture, including food, sleep, stress, labs, and your lifestyle, and find changes that feel doable. I'll offer ideas and ask good questions, and together we'll find the solutions that you can realistically make your own.

Medical Nutrition Therapy is often covered as preventive care, and many clients pay $0 out of pocket. Check your benefits or book a consultation to get started.

What to Expect

What to Expect from Virtual Nutrition Counseling in Portland, OR & Los Angeles, CA

I'm a Certified Nutrition Specialist (CNS) offering virtual nutrition counseling for cardiometabolic health, hormone health, and overall wellness. I'm based in Portland, OR and Los Angeles, CA, and I see clients in most states across the U.S. My job is to support you, and here's what that looks like.

Before your first visit

After you book your appointment, I'll send a detailed questionnaire about your health history, eating habits, sleep, stress, and goals. This is your space to tell your story in your own words and share what matters most to you. Taking the time to reflect can also surface patterns and connections you may not have noticed, and it helps us make the most of our time together.

Initial consultation (60 minutes)

This is a conversation, and you're the focus. I'll ask what's going on, what a typical day of eating looks like, and what you'd like to feel and do differently. Then we'll choose a few realistic first steps together, like prepping breakfast ahead of time, planning for mindless snacking, or getting labs done.

BOOK AN APPOINTMENT

Follow-up sessions (60 minutes)

Follow-up sessions are for celebrating what’s working, getting curious about what’s tricky, reviewing labs and supplements, and adjusting your plan as life changes. I'll ask whether your habits fit your goals, and when they don't, we'll explore what could work instead. I'll offer ideas, and you'll decide what feels doable. These visits provide accountability, helping you stay on track and feel supported as you make changes.  

Virtual visits are available in all states except AL, D.C., DE, FL, IA, KS, MO, MS, NC, ND, NE, OH, SD, and TN. Insurance coverage varies by plan and state, so check your benefits before booking.

Laboratory Services

Want to understand why your blood sugar is high, your cholesterol numbers keep creeping up, or your liver markers are out of range? Wondering why you feel tired or stuck despite being told your labs are “normal”?

Laboratory testing provides valuable insight into how your body is actually functioning. Blood work can reveal imbalances affecting glucose regulation, cardiovascular health, liver function, digestion, inflammation, nutrient status, and detoxification pathways long before a diagnosis is made.

Blood chemistry can reveal so much. It tells a story about patterns, stressors, and underlying drivers of symptoms. This information becomes a clear roadmap for creating a personalized nutrition, lifestyle, and supplement recommendations.

Using this approach ensures recommendations are targeted, intentional, and based on measurable findings rather than guesswork. The result is a more comprehensive and strategic path to improving health, energy, and long-term outcomes.

What Clients Are Saying

  • I have been working with Sharon for a few months, in the beginning she provided me with a very good plan (simple enough to follow, but great enough to make a real impact). I have truly noticed a major difference in my body, which positively impacts my mental health too! I appreciate Sharon's approach and personality, she is a great listener and really delivers.

    - Koen

  • I have been seeing Sharon since March this year and it has been one of the best decisions I have ever made. I used to constantly get sick and struggled with my health. With Sharon's help and guidance, we discovered I had a dairy allergy among other things. My quality of life has improved sooooo much!! If it was not for Sharon I would still be struggling. She listens and she genuinely cares.

    - Maria J. -Google

  • Working with Sharon gave me empathetic guidance for a complete lifestyle overhaul. I've been trying to DIY my diet and exercise routines, and the difference in effectiveness between having Sharon's expert knowledge and just "researching" on Reddit or from popular doctors online is huge. Diet is a habitual and emotional part of life that is often deeper than just food intake. Sharon's approach of meeting people where they are, keeping things measured and scientific with nutrient tracking and routine labs, and focusing on building a sustainable baseline works for me. Never in my life did I think I'd "crave" fiber and lifting weights, but Sharon made it happen. Also, much less period pain, eczema flare-ups resolved, better sleep schedule, less fatigue... insane. Thank you, Sharon!!

    - Sarah

  • It has been an amazing experience working with Sharon. Since working with her I have seen positive changes in my overall health and wellbeing. She has helped me establish a new nutritional routine. I have always had difficulty eating breakfast and getting enough protein and fiber in my diet and she taught me why these are so important! Sharon has helped me adjust my eating patterns which has made a huge difference in my digestive health. It has been incredible having someone so knowledgeable and kind as part of my care team.

    - E. L.

  • Sharon is incredibly knowledgeable, professional, and sensitive to my health issues and needs. After years of being dismissed by doctors and other health coaches, Sharon was able to give me answers to my gut health issues. She created individualized and attainable strategies for my health goals as well as encouraging alternative testing and approaches for my SIBO and hormonal imbalances. She has given me invaluable nutrition information that has helped me understand my body and how to best support it. I highly recommend working with Sharon. She is the ultimate nutritionist to support you through any nutrition needs!

    - Anonymous

  • It has been wonderful working with Sharon Ona. She has relived a significant amount of my stress in regards to my health concerns. I appreciate Sharon's wholistic approach to my individual care. I can't express how happy I am that I have found someone that listens and gives psychoeducational advice. I have the support I needed after trying to educate myself for years.

    - B. P.

  • I found Sharon to knowledgeable, thorough and professional. Working with her changed how I view everything I eat and eliminated the pain I was having after every meal. I highly recommend her.

    Aetna

    United Healthcare

    PacificSource

    CareOregon

    Most clients with eligible plans pay $0 out of pocket. Coverage depends on your specific insurance plan and benefits. Benefit verification is provided as a courtesy to you prior to your initial consultation.

  • Sometimes, but not always. Some insurance plans require a physician referral for nutrition counseling, while others do not.

    If you are located in California, a physician referral is required to see a nutrition professional for Medical Nutrition Therapy (MNT). Once your paperwork is completed, a referral request will be sent directly to your physician on your behalf. This is why completing your paperwork as soon as possible is important as it helps avoid delays in getting started.

    If a referral is required, I’ll let you know exactly what to expect and help make the process as smooth and straightforward as possible.

    You may download my referral form and provide this to your physician.

  • I am happy to cancel or reschedule your appointment at no charge with 48 business hours notice. If you provide less than 48 hours notice, your card will be charged a $100 late change fee. If you are 15 minutes late (or more) to your appointment without notice, this will be considered a no-show and your card will be charged the full visit fee ($195 for initial consultations, $130 for follow-ups).
