Empowering your health journey with data-driven knowledge about your natural cycles and hormones.
Having battled with energy, weight, mood, and sleep problems for much of my life, I understand the painstaking challenges of navigating the confusing and expensive world of traditional medicine. Now, through an understanding of circadian and quantum biology, I’ve taken control of my own health and I want to empower you to do the same.
I specialize in teaching individuals how to retrain the hormonal energy management system of their bodies - using the master signaling hormones leptin, melatonin, and cortisol - and incorporate proper nutrition to live a happy and healthy life. I’m a Quantum Health Coach, Certified Nutrition Coach, and ERYT, and I’m here to help you take control of your health!
Transform Your Health
My Core Values
Unfiltered, science-backed truth over comfort.
Knowledge as Power:
Being informed as an act of agency to reclaim your health and wellness
prioritization of mental and physical health over the habitual convenience of conforming to others’ opinions
with nature, with ancestral habits, and with ourselves
Health has been a consistent struggle for me throughout my life.
I’ve experienced adrenal fatigue, anxiety, bloating, depression, eczema, fertility issues, food addictions, gas, IBS, inflammation, ovarian cysts, PCOS, PMS, weight gain, and more. Not to mention, my sleep cycle was an inconsistent nightmare. I’ve been on and off prescription depression, anxiety, and sleep medications since I was fourteen years old, and I used to be over 100 pounds heavier than I am now. In a one year period, I spent over $100,000 on doctors’ visits, testing, blood work, and supplements . . . and saw no real improvements. I lost trust in standard allopathic medicine, as well as most functional medicine. In the last 10 years, I experimented with veganism, vegetarian diets, ketogenic diets, carnivore diets - you name it, I’ve probably tried it. At times it felt like strict diet control was helping: I lost 100 pounds (and then regained it, lost it again, regained it, and finally have lost it for good) but still felt like I was constantly fighting my body. I was exhausted - physically, mentally, and emotionally. And not to mention, constantly hungry.
No matter how hard I worked, how much I obsessed over diet and exercise, and how strictly I followed the orders of doctors and numerous health coaches, I couldn’t gain control over my physical health.
At the end of 2020, I hit a wall…
I was sick of being in a constant struggle for my health, and tired of spending thousands upon thousands of dollars with no solutions.
I suffered two miscarriages and knew my body was still out of control, but didn’t know where to turn.
Thankfully, at this time I was introduced to Dr. Jack Kruse, a respected neurosurgeon and longevity expert who has dedicated his practice to helping patients avoid healthcare burdens. I needed his help and was willing to do and learn anything in order to transform my health.
Overall, my mitochondrial health was suffering. I learned that my circadian rhythm was completely off, driven by a combination of a hormone imbalance and the amount of time I spent indoors in front of screens.
Leptin, along with cortisol and melatonin, is a master signaling hormone. I was leptin resistant, which, in turn, affected all downstream hormones including my immune system, thyroid, and sex hormones. Leptin resistance is a precursor to insulin resistance, so when I went to doctors in the past, they told me my insulin hormone levels were fine, overlooking leptin as a concern.
It is vital for leptin to dock to the hypothalamus while you sleep so that your energy output and appetite the next day are appropriate. My leptin resistance inhibited this from happening, resulting in problems with satiety, energy, and digestion.
Leptin was my lightbulb; this imbalance finally tied together what felt like my “broken metabolism.” This one hormone had the ability to dysregulate my entire system, and finally this knowledge was the first step on the pathway out of my struggles.
Knowledge is power, and understanding my own leptin resistance was the first key to getting my health on track.
I started paying attention to my circadian rhythm and regulating my master signaling hormones (leptin, cortisol, and melatonin); my health issues began to vanish.
I adjusted my diet and lifestyle in ways that connected me to my ancestral health, which felt authentic to my body and how it best functions naturally. I Incorporated mindfulness and self-care into my daily routine, prioritizing it as I do my diet and exercise. Gone are the crash diets and exercise obsessions.
When I started to see the optimal health that was available for me, I wanted to learn as much as possible, diving into quantum and circadian biology. The science-backed data empowered me to set up my lifestyle and nutrition to best support my body.
Now I feel the best I’ve ever felt in my life! Following my circadian rhythm has completely changed my health:
- I sleep soundly and wake up energized.
- I have a reliable appetite throughout the day.
- I conceived naturally at age 42.
- At age 43, I gave birth to a happy and healthy son named James.
- I’m taking no regular medications.
- I’ve been off of antidepressants for over eight years.
I am a Certified Nutrition Coach (CNC) from the National Academy of Sports Medicine and have the Applied Quantum Biology Certifications (Levels 1 and 2) from Quantum Biology Collective. My quest for knowledge is ongoing, so I’m regularly taking courses in quantum and circadian biology from the top specialists in these fields.
With my ever-growing knowledge and expertise, I have created and fine-tuned a comprehensive and holistic approach to my health. I want to share this wisdom with you so you can transform your own wellbeing, too!
Let’s work together to achieve your optimal health and vitality!
I want to help you balance your hormones, sleep better, feel better, and maintain your healthiest weight using the principles of circadian and quantum biology. Through seemingly small lifestyle changes, your health can transform in a life-altering way.
I want you to get back to feeling your best, without all the expensive tests and supplements you’ll find in the functional medicine world. You no longer need the all-consuming diet focus; you just need to be willing to try something new. The vast majority of my students see impactful vitality improvements in under three months as a result of subtle yet profound diet and lifestyle changes that re-balance the hormones - would you like to be one of them?
One of the core focuses of my programs is improving your mitochondrial health. Poor mitochondrial health is often the root cause of many diseases, and tackling this problem can lead to improvements in all areas of your health. I’ll teach you how to optimize your body’s energy management system so it can properly utilize the food you eat and you can start each day feeling revitalized.
This is the best course for my health I have ever taken! I was already doing so many things by just following Sarah online, and thought, “do I really need to do the course?” OMG I’m so glad I did! The information Sarah gives in the course and the knowledge behind all of it is priceless! I wasn’t doing sunrise the way I should have been, and now my routine has changed in a way that I feel so much better! Thank you so much Sarah - you are the best!

After years of keto & carnivore - and feeling like "the outlier" when it came to success and weight loss, this program was truly a God-send for me! The program is simple - yet so profound, and I learned so many fascinating things that were easy to apply in my daily life for big shifts and changes!

Wins: I Have way more energy. I'm not hungry right after I eat. I'm down to 3 meals a day rather than 5. When I get hungry I'm not noticing that extreme blood sugar dip. I'm on a healthier sleep schedule.
