McCall McPherson

McCall McPherson, PA-C, is the founder of Modern Thyroid Clinic and the force behind Thyroid Nation, a widely respected thyroid advocacy platform. As both a licensed physician assistant and a thyroid patient herself, McCall offers a unique and deeply personal understanding of what it means to struggle with thyroid dysfunction—and more importantly, how to overcome it.

Her own battle with undiagnosed hypothyroidism left her nearly non-functional in her twenties. Despite textbook “normal” labs, she was exhausted, symptomatic, and desperate for answers. That experience led her to discover that thyroid care is far more nuanced than just checking TSH and prescribing Levothyroxine. Once she cracked the code to her own healing, she made it her mission to help others do the same.

McCall has since become a TEDx speaker, the host of the Modern Thyroid & Wellness Podcast, & a frequent guest on podcasts and summits dedicated to hormone and thyroid health. Her passion is grounded in science, empathy. She lives by the idea that no one should have to suffer with thyroid symptoms that can be treated.

A graduate of Texas State University, McCall earned a bachelor’s degree in Psychology, graduating magna cum laude, & earned her master’s along with a second bachelor’s degree in Physician Assistant Studies at Mercy College in New York City. She began certification through the Institute for Functional Medicine in 2015 and has been integrating both traditional and functional medicine ever since.
