Student and Community Affairs Team

Amanda Runnels - Meet the Team

Amanda Runnels, NTP

Student and Community Affairs Manager


Hey there, I’m Amanda! I was born and raised in North Texas on a strict diet of local staples like Frito pies, fried fish, and buffet-style Mexican food. Fast forward a couple of decades and boy did I need a lifestyle change! Having developed several autoimmune conditions by my early thirties, it was time to get to the root of what was going on. This is what ultimately led me to the NTA, and I haven’t looked back since! I’ve learned that healing is 360 degrees — body, mind, spirit – and this is how I approach the work I am doing with my clients today. I’m an NTP, RWP, AIP Certified Coach, blogger, and a “mostly AIP/ Paleo” recipe developer. My husband would tell you I spend way too much time fiddling with my camera (or daydreaming about the beach), and my son would tell you how terribly I dance and sing spontaneously when 80’s or 90’s jams come on. I love the NTA community and am beyond grateful for this chance to give back to the institution that helped me reclaim my health!

My Favorite Fat: Avocado, all day every day! But cooking with bacon fat is a close second.

It was during this time that she discovered her true place was in holistic health.

Her playbook to success is meeting clients where they are to gently improve upon what they are already doing, introducing new concepts to gain early victories, and providing accountability to maintain patience and consistency over time. Jamie loves helping other


Mallory Acosta - Meet the Team

Mallory Acosta, FNTP

Vice President of Academics


Mallory is an FNTP with a heart for educating people about the incredible impact food can have on our wellbeing. With a B.A. in English and secondary teaching certificate, she spent years in the classroom witnessing the power education has to transform lives and unlock possibilities.

When a decade of health challenges threatened her dream of starting a family, she realized that despite living in an information age, the subject we know the least about is our own bodies. Determined to change her destiny, Mallory pursued an education with the NTA to learn how to nourish and support her health foundationally.

The simple, but powerful changes she and her husband made to their eating habits empowered them to welcome two incredible boys into the world. She has since made it her mission to equip other families with the knowledge and resources they need to thrive through food.

She and her family enjoy exploring the outdoors in the central mountains of Washington and dream of one day having a self-sustaining homestead. Always eager to learn more about the natural world, Mallory is also a Master Herbalist and is studying to become a Registered Aromatherapist. In her role as Vice President of Academics at the NTA, she is fulfilling her passion by supporting thousands of wellness champions as they share hope and health with their communities.

Thomas Gilliford - Meet your instructors

Thomas Gilliford, FNTP, BA

FCA Program Director and NTP Lead Instructor


Hey, Thomas here! I’m from Kansas City (Kansas) originally, where I earned my degree in economics at Rockhurst University. Currently, I am sick of the subpar BBQ in Denver, where I’ve made my home with my lovely family. I’m a father of three: one human, one cat, and one pup, the favorite being the one that is least messy that day.

I’m an FNTP, Structural Integration Practitioner and sworn mortal enemy of pain! Having spent too many years experiencing my own issues I embarked on a quest to master various healing techniques from the ancient masters. I couldn’t find them. But I have been a practicing bodyworker since 2011 and FNTP since 2014, combining the practices to help people live their lives the way they want to.

My true passion, however, is teaching, which I have done in some capacity for the Nutritional Therapy Association since 2016. In addition to being the Subject Matter Expert for Sleep, Stress and Nutrient Dense Diet at NTA, I run a case study group for graduates to keep both them and myself sharp! Some things I enjoy doing – besides educating students and helping clients – are trying new restaurants, foregoing new restaurants for old favorites, and complaining about the quality of tea at most coffee shops. I like food, and I want you to like it too.

Jessica Pantermuehl - Meet the Team

Jessica Pantermuehl, FNTP

Career Development Course Lead Instructor


I’m Jessica, a Texas native, Los Angeles transplant, and the Lead Instructor for the Career Development Course here at the NTA.

When I’m not devouring the latest books in business, marketing, or functional nutrition, brewing up ferments like a mad scientist in my kitchen, or basking in the sweaty glory of my infrared sauna, you can find me helping practitioners launch and grow their businesses here at the NTA and as the founder of the Holistic Entrepreneur Association.

Amanda Jones - Meet your instructors

Amanda Jones, MS, BA, FNTP, LMT, A-CFHC

NTP Lead Instructor


I graduated from the NTA in 2013, and over the past decade, I’ve found many different ways to put my NTP training to use – whether it is making a hearty batch of soup for loved ones, teaching kids in public schools about oowee-gooweee SCOBYs, working as an adjunct practitioner in a medical clinic, leading groups, private practice, copywriting and marketing for others, or helping my farming friends come up with a new recipe for market. In my practice, I’ve specialized in digestive function and cardio-metabolic imbalances, but as every NTP will tell you, “it all comes back to the foundations!” My work as an instructor requires me to be a life-long learner, which I am grateful for.

In addition to my FNTP certificate, I also hold an MS in Human Nutrition and Functional Medicine, a BA in Communications, and am a certified ADAPT Functional Health Coach and certified GAPS Practitioner. As so many before me, I found my way to this field while seeking answers to my own health concerns, but then discovered an enthusiasm for nutritional science that went far beyond my expectations. I love how many aspects of our lives and values intersect around food and nutrition – it makes for an endlessly fascinating field of study and opportunity to serve.

Allison Mädl - Meet your instructors

Allison Mädl, FNTP, BA

NTP Assistant Instructor


Hello! My name is Allison Mädl (rhymes with “ladle”). I am a Functional Nutritional Therapy Practitioner with a private practice in Coeur d’Alene, Idaho. I help women with chronic feminine health issues balance their diet and lifestyle so they can find freedom from discomfort and enjoy stable moods, restful sleep, normal weight, and healthy children. My ultimate vision is that families are empowered by the knowledge of traditional nutrition to maximize their health potential and grow strong children who continue the wellness revolution! I consult with private clients both in the United States and abroad using the NTP paradigm, RESTART program, and Hair Tissue Mineral Analysis.

My academic background is in secondary education. From 2007 – 2016 I taught English, Spanish, and English Language Development (ELD) in diverse public high school settings in Southern California and Washington state. My ELD students were primarily from indigenous parts of Mexico and Central America, as well as others representing refugee populations from various parts of the world. Working and conversing with these students piqued my interest in traditional foods and led to an ongoing research investigation of native food practices. Putting my teaching experience to use in the nutrition field, I have been an instructor for the Nutritional Therapy Association since 2015.

I also was lucky enough to be the Student Affairs Specialist for the NTA from 2018-2023, where I assisted NTP students with multifarious needs from academic progress to understanding their options in the program to coordinating the graduation process and mailing of certificates.

In 2016, my husband and I relocated to beautiful North Idaho after an extensive search for clean air and water and easy access to high quality, nutrient-dense foods. We enjoy raising our son here and supporting the local food economy.
