Sarah Prender

McCall McPherson, PA-C
Executive Assistant
Sarah brings over 20 years of experience as an executive and personal assistant, where she mastered the art of organization, communication, and proactive problem-solving.
Throughout her career – from startups in Palo Alto, CA to a luxury real estate team in Austin, TX – she honed her ability to support executives under pressure, build trust quickly, and navigate complex, fast-paced environments with care and precision.
Her personal journey with hypothyroidism brought her to Modern Thyroid Clinic as a patient, where she finally felt heard, understood, and empowered. That experience inspired her to join the team in an Executive Assistant role, where she combines her professional expertise with her personal insight to provide seamless support, anticipate needs, and help leadership focus on strategic priorities.
Sarah is deeply committed to ensuring smooth operations, clear communication, and proactive problem-solving across the organization. She thrives on creating efficiency, keeping projects on track, and supporting the team so they can operate at their best.
Outside of work, Sarah enjoys playing sports, running, working out, and spending time with her husband and kids in their hometown of Leander, Texas.
