McCall McPherson is the visionary of Modern Thyroid Clinic and the owner of Thyroid Nation, a large thyroid advocacy platform. She is a physician assistant, recent TEDx speaker and a thyroid expert by way of being a thyroid patient. She has been a guest on numerous podcast and summits discussing various topics on thyroid and hormone issues and now hosts Thyroid Nation Radio. Her passion for perfecting thyroid treatment stemmed from years of her suffering due to the mismanagement of her own hypothyroidism. Now she lives, breathes and thrives in understanding the nuances of proper thyroid care. Her philosophy is simple: There is no reason to still have thyroid symptoms. She spends her time helping to make it so by giving her patients get their lives back and teaching and advocating for the other millions suffering who aren’t her patients. You can get a more in-depth understanding of who I am and how I practice on my website at www.mccallmcpherson.com. I ended up in this fascinating niche of medicine for a few reasons. The most profound was my own case of hypothyroidism, that I simply could not get managed and left me almost non-functional for more than 6 months. Repeatedly I went to my doctor begging for help, asking that he look deeper than my TSH which was “normal,” even though I was 27 years old and literally going to bed at 3:30 in the afternoon, not to mention I had almost every last symptom of hypothyroidism. It wasn’t until I learned that thyroid disorders are much more complex to diagnose and treat than a simple TSH and Levothyroxine, that I got my life back. Years later for obvious reasons, my passion runs deep for solving people's thyroid problem; it's my jam and my life’s calling. Professionally speaking, I'm a licensed and nationally certified Physician Assistant with prescriptive authority. I graduated Magna Cum Laude with a Bachelor's Degree from Texas State University in Psychology in San Marcos, Texas. I then packed up my bags and moved to New York City to earn a Master’s Degree as well as an additional Bachelor’s degree in Physician Assistant Studies at Mercy and began my certification from the prestigious Institute for Functional Medicine in 2015. I love and live in Austin, with my two daughters, Weston and Rose. In my free time I enjoy exercise, live music, spending time outdoors, and traveling.
Yari graduated from Texas A&M University in 2004 with a Bachelor of Science degree in Psychology. She received her Masters in Physician Assistant Studies from Texas Tech University Health Sciences Center in 2005. She worked in the fields of neurosurgery and pain management before transitioning to functional medicine, and specifically thyroid treatment, after she attended a life-changing education conference on hormones 2 years ago. During the conference, she experienced a total paradigm shift in how she viewed the current medical model of care, especially the treatment and management of thyroid and hormone dysfunction. Yari went from accepting the status quo recommendations and guidelines, to challenging what she had been taught, and exploring treatment options that addressed the root cause of a condition. Once she began implementing these changes in her practice, she saw firsthand the profound impact such treatment can have on a patient’s quality of life. Yari is excited to work with each of her patients to achieve their health and wellness goals. Yari lives in Austin with her husband and two daughters. She enjoys reading, running, and hiking the Greenbelt with her girls.

She began her career at the MD Anderson Cancer Center in Houston as a Physician Assistant in reconstructive plastic surgery where she had the honor of participating in life renewing surgery and patient care. It was at this time that Laurie began to appreciate what could be achieved when one looks beyond the boundaries of traditional medicine. In a move overseas, living as an expat in Australia, Laurie gained a renewed appreciation for active lifestyles, personal health, and clean nutrition through easy access to local, organic foods, a strong wellness and fitness culture, and a population more open to non-traditional means of combating illness and hardship. Seeking a path by which she could apply this experience and mindset, she accepted a clinical role in gastroenterology in 2016. While working in GI, Laurie found a great satisfaction in finding the root cause of ailments, often after patients had experienced years of symptoms. She deepened her knowledge as a functional and progressive practitioner in the areas of gut health, micronutrient testing, food sensitivity testing, via treatment protocols nutritional enhancements, and diet coaching. Inspired by the results achieved from physiotherapy, Laurie also received her Certificate in Dry Needling in 2021.) Laurie continues to expand her knowledge and understanding of the impacts a western society and hurried culture can have on the health and well-being of her family, friends, and patients. She believes strongly in self advocacy in medicine, the limited mindset of some areas of traditional medicine, and the need for individualized, patient-individualized care. She has witnessed the dismissal of her close friends by their doctors with their thyroid struggles. Laurie enjoys traveling with her children and husband, reading, and recreational crossfit.

Melody graduated in 2008 with a Bachelor of Science in Nursing from the University of Texas at Austin. She went on to get a Master of Science in Nursing, also from the University of Texas, and become a certified Family Nurse Practitioner in 2014. After getting her bachelor’s degree, Melody worked for 5 years at Dell Seton Medical Center and has spent the last 5 years working in primary care with a focus on thyroid disorders and hormone imbalances. Melody’s personal thyroid journey began as an 18-year-old freshman in college when she started having overwhelming fatigue, brain fog, and sleep disruption. After being told she was “just a tired college student”, she dug deeper into her own health and was finally diagnosed with hypothyroidism and Hashimoto’s. Since then, she has spent the last 17 years developing her passion for helping others that are suffering like she was and sharing with them what she’s learned about thyroid and hormone support, not only as a clinician, but also as a patient herself. Melody’s philosophy is simple - no two patients are alike. While thyroid and adrenal hormones impact every single cell in the body and cause a myriad of symptoms if unbalanced, often patients have their own individual set of symptoms unique to them. When a person is unwell, their whole life can unravel and that affects more than just a set of labs or their symptoms, it is often the underlying core of their entire wellbeing. Melody is committed to treating her patients as individuals, not just a set of one-size-fits-all lab results and works with each one to achieve optimal hormone levels that leads to a life of overall wellness and balance. Melody lives in Austin with her husband and 2 young daughters and enjoys being outside, running, reading, listening to music and spending time with her family and friends.
