Samantha Thiry,
FNP-C,Clinic Leader & Board-Certified Family Nurse Practitioner
Samantha Thiry is a board-certified Family Nurse Practitioner and founder of Happy Body ATX, PLLC. A pediatric cancer survivor, she learned early that life is an incredible gift—and that compassionate, evidence-based care changes everything. Over the past 10+ years as a medical provider, Samantha has focused on prevention and health optimization, helping patients understand which tools, supplements, and supervised therapies can support real, sustainable progress.

Samantha bridges thoughtful, root-cause assessment with up-to-date research on supplement support and safely monitored hormone-balancing protocols. She believes patients deserve clear options and straight answers—especially when traditional models don’t fully address the “why” behind symptoms.
Above all, Samantha practices a private, patient-centered approach. She welcomes the hard conversations, protects confidentiality, and partners with each person to create a plan that fits real life. In leading True Weight Loss Clinic, she carries forward Dr. Thiry’s legacy of kindness, integrity, and results that last.
