About us

A practice built on trust, continued with care.

Three decades of medically supervised weight loss in Central Texas — and a leadership transition that keeps every standard our founder built.

Over 30 years of practice
Our story

From founder's vision, to continued excellence.

For over three decades, True Weight Loss Clinic has been Central Texas's trusted partner for medically supervised weight loss and wellness — a practice founded on the belief that real care means real relationships.

Dr. Craig Thiry built this clinic around standards that don't bend: personal attention, real clinical oversight, and a commitment to every patient as an individual. Today, Samantha Thiry provides day-to-day leadership and is continuing those same standards — bringing the same dedication, the same team, and the same care our patients have always known.

Patient continuity

Common questions.

Is the same team still here?

Yes. Our clinical team and providers are the same trusted faces you've known. Samantha Thiry continues the day-to-day leadership of the practice with the standards Dr. Craig Thiry established.

Will my treatment plan change?

No — your care continues as before, with the same providers, programs, and approach. If anything changes about your specific plan, your provider will discuss it directly with you at your next visit.

Do you accept insurance?

Most of our services are self-pay, which keeps our pricing transparent and our care flexible. Some lab work may be eligible for HSA/FSA reimbursement — ask our team at your visit.

How do I become a new patient?
