Sydenham Clinic

River Oaks, Houston

More sanctuary than clinic, this space is where the Sydenham philosophy took form - thoughtfully, precisely, and always in service of longevity.

The First Expression of Sydenham Medicine  

Houston is where Sydenham began. Set in a calm, contemplative space minutes from the Texas Medical Center, it is where Sydenham’s standards were first created, tested, and refined.

Where the Method Was Built

The birthplace of the Sydenham Method. Our seven-pillar framework was shaped through deep clinical reasoning, long-form consultations, and unhurried care-guided by one principle: know the patient fully and intervene early.

A Sanctuary for Precision Care

More sanctuary than clinic, the Houston location remains the intellectual and clinical foundation of Sydenham-focused on precision, continuity, and longevity.
