Nutrition Coaching

Life with more energy, better health, and more JOY awaits!


You just want to feel your best. But life seems to have other plans.

I get it. And I’ve even been there myself. As a mom, runner, and everyday athlete, I’ve needed help navigating life’s various stages: postpartum, raising kids, lack of energy, changes in my body, and everything in between. 

If you’re struggling to get back into your fitness routine after having kids, or you’re feeling like something is “off” with your body but your doctor isn’t listening… This is the place for you. I don’t want you to resign yourself to a life of fatigue, gut problems, and movement challenges. Instead, I want to help you reach your physical goals — whether that’s getting back into your beloved physical activities or reaching your level of optimal health.

You deserve to unsubscribe from the frustrating cycle of different doctors, zero answers, and resorting to what you’ve always been told about your body. You deserve to feel your best.

Using my experience as a Registered Dietitian, knowledge of nutrition, fitness, and hormones, I’ll help you create a roadmap that helps you reach your goals and enjoy life (and movement) again!


A comprehensive, 6-month plan designed for you and your fitness goals.



Before we can grow, we need a good foundation and good soil. This means restoring energy and body safety with sufficient nourishment. We start with eating enough, hydrating properly, and managing needs for sleep and rest.



This is where we can start to utilized targeted testing, looking at digestion and detoxification support, and consider how our environment affects the healing process from a physical, relational, and information consumption standpoint.



Now that the body has sufficient fuel and the gut has been supported, we have capacity to look at the brain and nervous system. This is the hard work of challenging subconscious beliefs, rewiring the brain, and building a strong nervous system support toolbox to handle the stress load of every day life and training needs.



Once the body is primed, we finally look to hormone health, thyroid and metabolism needs, as well as iron recycling imbalances to ensure lasting energy to start chasing the big, scary fitness goals you really want to go after. We review activity needs and craft a custom fitness plan based on your health goals and progress to date. 

What to expect when we work together

I know that working with a Registered Dietitian and nutrition coach might feel overwhelming. But I make it super easy to work together, focusing on your current health and where you want to be in 6 months.


We’ll have an hour-long video call, where we’ll review your completed intake forms, walk through your six-month plan, and review testing needs and lab work. We’ll also discuss future communication plans and set expectations for both you and me.


During your 6-month coaching plan, we’ll communicate consistently through weekly check-in emails. I’ll ask you questions, share resources, and provide personalized guidance regarding your fitness, training, nutrition, and hormones.


We’ll conduct follow-ups and check-ins via 30-minute phone calls, where we will discuss how you’re feeling, talk about changes, and celebrate progress! These calls give me a chance to get a better sense of your current state beyond our weekly check-in emails.


After your 6-month coaching plan, if you want to continue your health journey with me, we can discuss options for month-to-month coaching and individual follow-up sessions. Please note that all clients must complete 6 months of coaching before requesting or scheduling monthly coaching or follow-up sessions.

“I have been struggling nutritionally through Candida and trying to fuel my body for workouts and daily life. I knew I needed help! I was excited to do the HTMA so I could have a plan in place. I’ve been on a struggle bus for far too long. I’m excited to try something different and get my body back.” – Jessica

“I was flagged by my endocrinologist as being “iron deficient” due to low ferritin levels in my routine blood work. An appointment with a hematologist and four iron infusions later, supposedly I was good to go. Except I wasn’t.

Stephanie recommended that I do HMTA testing to see what was actually going on in my body. I had an iron dysregulation problem. Since that discovery, I’m not exaggerating when I say my skin was settled and back to normal within a month. My energy is back up again too, and my hair is not falling out in chunks anymore. 

I wanted to share this so that others know that there’s hope! I strongly believe that every athlete needs a coach AND a dietitian. They are not the same thing, and they are both crucial for overall health and optimal performance. Stephanie is a diamond because she’s a dietitian who is an athlete.” – Megan

“I know how to maintain my well-being now: what to eat, what to avoid, how to protect my sleep, how to manage stress, and how to be kind to my body.

Stephanie accomplished what rheumatologists, physical therapists, and acupuncturists couldn’t. She gave me a holistic nutritional and fitness makeover. She’s knowledgeable and, most importantly, she really cares.” – Monica

“I was able to completely clear up the histamine reactions I was seeing and learn what macros matched where I needed to be to have a balanced diet that supported my activity. I would absolutely recommend Stephanie because she really listens and helps you learn how to make tweaks without turning your life upside down. Everything was very approachable and easy to see what was working and what needed to be tweaked. I feel like I have skills for life to take forward.” – Jenna

Frequently Asked Questions about Female Athlete Nutrition Coaching

Will my insurance cover these coaching & running services?

It depends! While I do not take insurance, I am always happy to create a superbill for you to submit to your insurance for reimbursement.

Are you local and in-person, or is everything virtual?

Although I proudly live in Colorado, all of my coaching services are done virtually and I welcome clients from all across the US. All sessions are done via a HIPAA secure telehealth portal, which allows for client privacy, ease of scheduling, and access to clients across the country.

Is hormone testing included with your services? Which tests do you order?

Depending on the service, functional lab testing is included. Some testing can be ordered a la carte. I currently offer HTMA, GI MAP, DUTCH, specialty labs, and micronutrient testing.

What’s the difference between Endurance Coaching and Functional Nutrition Coaching?

Most of my coaching process is the same between the two. For women who are avid runners and potentially want to race again, I develop more specific training and nutrition recommendations because running has different impacts on the body vs. general fitness. For women who have more complex symptoms and need for functional lab testing, or who simply want to get back into a fitness routine, I develop recommendations based on those unique goals.
