I use clinically proven strategies to get women happy, healthy, and fit quickly and naturally.

For 20 years, I’ve helped women transform their bodies, health, energy, and mood by addressing the root causes of weight gain and stubborn symptoms that conventional diets, workouts, and medicine often overlook, and often make worse.

On average, my clients report symptom improvements within the first week and typically lose 20 pounds in 75 days.

Think you can handle results like that?

Good. Because that’s exactly what happens when you follow my programs or work with me.

WHAT MAKES ME DIFFERENT

With me, you get a Doctor of Functional Medicine, Nutritionist, and Trainer rolled into a results oriented one stop shop.

Most women struggle because they’re mixing different doctors, nutritionists, diets, trainers, supplements, and workout programs, but don’t look or feel better long term.

Why?

Because none of it is designed to work together and this approach doesn’t address the root cause of stubborn fat and symptoms. This makes weight gain & symptoms worse.

I got stuck in that trap too and knew there had to be a better way. There is. Here’s what I do instead:

I combine fat loss, physical health, mental health, and healing into all of my nutrition and workout programs to address what’s causing stubborn fat and symptoms so you’re able to get results quickly and naturally.

This way you lose weight and feel great, and stay that way.

Combining my workouts with my meal plans is the full solution most people never get. With me, you do.

HOW I GOT STARTED

Once upon a time I was 40 pounds overweight and struggled with lots of physical & mental health issues that no one could explain or fix.

I tried the usual advice. It didn’t work. And in some ways, it made things worse.

I knew there had to be a better way, so I started digging. That search is what turned me into a trainer, a nutritionist, and a Doctor of Functional Medicine.

I used food and simple exercise to transform my body, my mind, and my life. Now I help other women do the same.

Me Then…

  • Struggled with weight, confidence, & cravings
  • Always starting over & Yo-Yo Dieting
  • Frustrated, depressed, and anxious
  • Losing weight, regaining it, repeating the cycle
  • 40 pounds heavier than I am today
  • On 7 different medications

Me Now…

  • Thriving, confident, complete control over food
  • Healthy, energized, eating for my metabolic type
  • Feeling good feels effortless
  • Lost the weight – kept it off
  • If I get off track I easily get back on
  • Zero medications – Just food and exercises that actually work 

WHO I WORK WITH

If you’ve been doing all the “right” things but your body isn’t responding, it’s not willpower. It’s biology, and it’s fixable.

I work with women who are ready to:

  • Lose stubborn weight and keep it off long term
  • Heal their gut, balance hormones, and calm inflammation
  • Boost energy, sleep better, and feel like themselves again
  • Stop guessing and start knowing what their body actually needs
  • Look great and feel even better

If you’re nodding along, you’re exactly who I help.

Frequently Asked Questions
What kind of training did you receive?

I am a Doctor of Functional Medicine (DFM), Functional Diagnostic Nutrition Practitioner (FDN-P), Holistic Nutritionist (HN), and Personal Trainer. I received my doctorate in Functional Medicine from Rockwell School of Holistic Medicine. My pre doctorate education and training is in Functional Nutrition & Holistic Health and Metabolic Health.  I have received complete training in the biological sciences such as anatomy, physiology, pathophysiology, epidemiology, gastroenterology, endocrinology, parasitology, and functional blood chemistry. In addition, I have received extensive training in clinical nutrition, botanical & herbal interventions, somatic healing practices, trauma, and behavior modification and lifestyle counseling.

Do you prescribe Medication?

Nope! I don’t prescribe or adjust prescription medications or controlled substances—that’s a job for your prescribing medical doctor. My role is to help you feel better (and stay better) using safe, natural, and non-invasive approaches. Think nutritional therapy, targeted supplements, functional herbs, stress-relieving techniques, and lifestyle shifts that address the root causes of what’s going on in your body. My goal is to get you back to optimal health and function—without the side effects and frustrations that so often come with a “just take this pill” approach.

Do you take Insurance?

I don’t bill insurance. Functional Medicine is still considered “outside the box” by most insurance companies, so the majority of my services are elective and not covered.

That said, my online programs and one-on-one services are eligible for FSA (Flexible Spending Account) & HSA funds – which can be a great way to use pre-tax dollars for your health.
