CEO - Founder
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 Thyroid Nation Radio, and a frequent guest on podcasts and summits dedicated to hormone and thyroid health. Her passion is grounded in science, empathy, and a philosophy she lives by: No one should have to suffer with thyroid symptoms that can be treated.
She’s a graduate of Texas State University, where she earned a bachelor’s degree in Psychology, magna cum laude. She then earned her master’s and second bachelor’s degrees 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.
McCall lives in Austin, Texas, with her two daughters, Weston and Rose. When she’s not seeing patients or advocating for better thyroid care, you’ll find her enjoying the outdoors, listening to live music, working out, or planning her next travel adventure.
