The Authority in Personal Injury Clinical Care in the RGV
Led by Dr. Paul Sta. Juana, DC and Liza Sta. Juana, PT (35+ years combined experience). We provide law firms across Hidalgo and Cameron counties with uncompromising clinical integrity, defense-grade documentation, and zero out-of-pocket client friction under 100% Attorney LOP Liens.
Direct Clinical Oversight by Senior Directors
We reject the high-volume assembly-line model. When your clients are treated at South Texas Accident & Injury, their examinations, spinal decompression, and functional physical therapy are directly performed by senior clinicians.

Dr. Paul Sta. Juana, DC
Personal Injury Clinical Director & Certified Cox® Practitioner
Specializing in severe crash trauma, disc herniations, and radiculopathy. Dr. Paul is the only certified Cox® Technic Flexion-Distraction clinician in Deep South Texas, delivering federally researched decompression that gently opens collapsed disc spaces and relieves trapped nerve roots.
Every medical chart features precise inclinometric range-of-motion metrics, dermatomal mapping, and objective disc injury reports structured specifically to withstand defense adjuster scrutiny.

Liza Sta. Juana, PT
Physical Therapy Director & Rehabilitation Specialist
With over three decades of clinical practice across the Rio Grande Valley, Liza Sta. Juana leads our active rehabilitation suite. She specializes in post-surgical recovery, spinal ligament stabilization, and breaking down restrictive myofascial scar tissue following high-impact whiplash.
Having a licensed physical therapist co-managing your client under one roof eliminates the “passive chiropractic care only” defense argument, verifying true functional restoration of Activities of Daily Living (ADLs).
Why Adjusters Settle Our Demands Faster
We designed our clinical protocols from the ground up to protect your client's physical health and your firm's settlement value.
Passive Care & Cut-and-Paste Notes
- Unlicensed Technicians: Clients are passed to aides and rarely evaluated by the doctor after Day 1.
- Passive “Table-Warming”: 3 months of hot packs and electric stim with zero active structural rehabilitation.
- Vague, Subjective SOAP Notes: Adjusters slash medical specials because records lack objective impairment measurements.
- Settlement Roadblocks: Weeks or months to receive final narrative reports and billing balance verifications.
Direct Doctor Care & Defensible Proof
- 100% Senior Clinician Care: Every session conducted hands-on by Dr. Paul Sta. Juana, DC and Liza Sta. Juana, PT.
- Active Structural Reconstruction: Certified Cox® flexion-distraction decompression combined with active PT core stabilization.
- Objective AMA Impairment Data: Inclinometric ROM, dermatomal sensory audits, and spinal ligament laxity documentation.
- Strict 48–72 Hr SLA: Narrative reports, complete SOAP records, and final itemized ledgers delivered without delay.
