McCall McPherson: Pioneering Weight Loss Solutions for Thyroid Patients

McCall McPherson, PA-C, is the founder and CEO of Modern Thyroid Clinic and co-founder of Modern Weight Loss, where she leads innovative programs designed to help individuals with thyroid and metabolic conditions achieve sustainable weight loss. Her approach combines GLP-1 medications like semaglutide and tirzepatide with personalized medical supervision, lifestyle support, and laboratory monitoring to address the root causes of weight loss resistance in patients with hypothyroidism and Hashimoto’s thyroiditis.

Modern Thyroid Clinic’s Modern Weight Loss program, launched in fall 2022 with semaglutide, has expanded to include tirzepatide and is now available to patients nationwide in licensed states, excluding Alabama, Arkansas, and Connecticut. The program offers tiered pricing options, including a one-month trial at $497 and discounted 3-month bundles for semaglutide ($990) and tirzepatide ($1,290), which include initial consultations, weekly check-ins, medication, lab analysis, nutrition guidance, and access to a supportive community via weekly Q&A Zoom calls.

McPherson’s expertise is frequently featured in trusted health platforms, including her appearance as a guest on the Thyroid Pharmacist podcast, where she discussed how GLP-1 medications, when microdosed and paired with lifestyle interventions, can help thyroid patients lose weight while improving metabolic function and reducing inflammation. She emphasizes that weight loss resistance in thyroid patients is often not due to calorie imbalance alone but is influenced by underlying hormonal dysfunction, nutrient deficiencies, and poor T4-to-T3 conversion — factors her programs aim to address through precision medicine.

As a physician associate and entrepreneur in thyroid, hormone, and metabolic health, McCall McPherson continues to advance access to science-backed, practitioner-led weight loss solutions that prioritize safety, individualization, and long-term metabolic healing over short-term fixes.
